Add Concurrent Load Testing, AWX Integration, and Enhanced CPU Management

Summary

This PR introduces significant enhancements to the vLLM CPU performance evaluation framework:

  • 3-Phase Concurrent Load Testing: Implements a comprehensive concurrent load testing methodology with warmup, calibration, and production phases to accurately measure vLLM performance under realistic multi-client workloads
  • AWX Integration: Adds full Ansible AWX (Automation Platform) support with custom execution environments, auto-imported job templates, and KIND-based deployment for automated test orchestration
  • Intelligent CPU Allocation: Implements NUMA-aware CPU core allocation with automatic tensor-parallel calculation across multiple NUMA nodes, including improved type safety and backward compatibility
  • Core Sweep Automation: Introduces bash-orchestrated core sweep testing with automated result collection and timing extraction
  • Security Hardening: Prevents HF_TOKEN exposure in logs and AWX configurations
  • Enhanced Documentation: Comprehensive inline documentation for playbooks, testing phases, and AWX deployment workflows

Key Changes

Concurrent Load Testing (llm-benchmark-concurrent-load.yml)

  • 3-phase testing methodology: warmup → calibration → production
  • Support for concurrency levels 2, 4, 8, 16, 32 for fine-grained CPU testing
  • Variable token workloads with explicit prefix caching configuration
  • Intelligent timeout calculation based on concurrency and rate limits
  • Results organized by test_run_id to prevent contamination

AWX Integration (automation/test-execution/awx/)

  • KIND-based deployment for AWX 24.x+ (Makefile)
  • Custom execution environment with pre-installed Ansible collections (execution-environment.yml)
  • Automated playbook import as AWX job templates (configure-awx.yml)
  • Auto-detection of current git branch for project configuration
  • GuideLLM debugging tools for troubleshooting container issues
  • Comprehensive setup documentation (README.md, RUN-EC2-TEST.md)

CPU & NUMA Management (filter_plugins/cpu_utils.py)

231-246: ⚠️ Potential issue | 🟠 Major

Stream GuideLLM container logs directly to disk instead of buffering in Ansible memory.

The current approach registers full podman logs output into the guidellm_full_logs variable before writing to disk. For long-running or concurrent benchmark sweeps, this holds the entire log content in Ansible's memory, creating unnecessary memory pressure. Instead, pipe the output directly to the temporary file using shell redirection in a single task.

Fail on any podman wait command error, not only timeout.

The current failed_when: guidellm_exit_code_container.rc == 124 only treats timeout (exit code 124) as a failure. If timeout/podman fails for other reasons—such as a missing podman binary (exit code 127), command not found (126), or other errors—the task will incorrectly report success and execution continues, masking real environment problems.

In @.github/workflows/build-execution-environment.yml:
- Around line 8-12: Update the workflow's trigger paths list so changes under
the build context re-run the EE build: in the YAML block that contains the
"paths:" array for the workflow trigger, add "context/**" to the list (alongside
the existing entries) so that any edits to files under the context directory
(e.g., Containerfile or context/_build scripts) will trigger the workflow.
- Around line 121-138: Replace the hardcoded :latest tag used in the summary and
verification steps with the same tag variable used when publishing so the
workflow verifies the image produced by this run; specifically, change the
"image: ${{ env.REGISTRY }}/${{ env.IMAGE_NAME }}:latest" echo line and the
podman pull/inspect invocations to use the run's tag variable (e.g., ${{
inputs.tag }} or an env var you set like ${{ env.IMAGE_TAG }} that is populated
from inputs.tag earlier) so both the GH step summary and the Verify image step
reference the exact pushed tag.

In `@automation/test-execution/ansible/llm-benchmark-concurrent-load.yml`:
- Around line 55-67: The "Validate required parameters" assert is too strict: it
requires requested_cores and blocks the documented sweep entrypoint using
core_sweep_counts; update the validation to accept either a single
requested_cores or a sweep list core_sweep_counts (e.g., ensure that at least
one of requested_cores is defined and >0 or core_sweep_counts is defined and is
a non-empty list of positive ints), or alternatively set requested_cores from
core_sweep_counts when the latter is provided; adjust the assertion conditions
to reflect this (references: requested_cores, core_sweep_counts, and the
"Validate required parameters" task).

In
`@automation/test-execution/ansible/roles/common/tasks/detect-numa-topology.yml`:
- Around line 91-101: The backward-compat logic assumes contiguous NUMA IDs;
update the calculation to pick actual node IDs from numa_nodes_inventory rather
than hardcoding positional IDs: set housekeeping_node_id to the id of
numa_nodes_inventory | first, guidellm_node_id to the id of numa_nodes_inventory
| nth(1) when available (else same as first), and vllm_node_id to the id of
numa_nodes_inventory | last; then use those IDs in the existing selectattr
lookups (housekeeping_node_info, guidellm_node_info, vllm_node_info) so
selectattr('id','equalto',...) matches real node ids and avoids undefined
node_info when dereferencing .all_cpus/.physical_cpus/.physical_cpus_list.

In
`@automation/test-execution/ansible/roles/vllm_server/tasks/start-embedding.yml`:
- Around line 98-99: The HF_TOKEN is being constructed in a non-masked set_fact
task (the set_fact that concatenates or assigns HF_TOKEN), so even though later
container start tasks use no_log: true the secret can still appear in logs;
update the set_fact that creates HF_TOKEN to include no_log: true (or refactor
to pull HF_TOKEN directly via a no_log-safe lookup such as env
lookup/ansible-vault) so the token is never emitted in plaintext in any task
output (refer to the set_fact task that assigns HF_TOKEN and the container start
tasks that already use no_log).

In `@automation/test-execution/ansible/roles/vllm_server/tasks/start-llm.yml`:
- Line 249: The HF_TOKEN value is still exposed because it’s created via a
set_fact task (the set_fact that assigns HF_TOKEN) without no_log; update that
set_fact (the task that sets HF_TOKEN) to include no_log: true (and remove any
debug/register that prints or logs the variable thereafter) so the secret is
never emitted in task output; ensure any downstream tasks that reference
HF_TOKEN also avoid logging it (no debug or verbose registration) to prevent
leakage.

In `@automation/test-execution/awx/configure-awx.yml`:
- Around line 570-579: The debug task named "Configuration complete" currently
prints controller_password in plain text; update the ansible.builtin.debug msg
to avoid exposing credentials by either removing the controller_password entry
or replacing it with a masked value (e.g., fixed asterisks or a partially
redacted form showing only last 4 chars) and keep controller_host and
controller_username unchanged; edit the message list in that task so no variable
expands to the raw controller_password.

In `@automation/test-execution/awx/README.md`:
- Around line 605-607: Remove the recommendation to run "sudo setenforce 0" from
the README and replace it with a security-safe remedy: explain that SELinux
should not be disabled host-wide and instead instruct users to apply the correct
SELinux file/context labels or policy changes (e.g., using semanage/restorecon)
for the container files, or to run the container with appropriate Podman flags
(such as --security-opt label=disable or --security-opt label=type:container_t)
for a per-container workaround; update the bullet under "Fixes" that currently
lists "Permission error? `sudo setenforce 0`" to one concise line pointing to
these label/policy steps and/or Podman flags and, if useful, link to official
SELinux/Podman docs.

In `@automation/test-execution/awx/RUN-EC2-TEST.md`:
- Around line 4-6: Replace the hardcoded developer-specific values in the
RUN-EC2-TEST.md (lines showing "DUT", "Load Generator", "SSH key path", and
"Project Branch") with reusable placeholders: replace the EC2 hostnames with
<DUT_HOSTNAME> and <LOADGEN_HOSTNAME>, replace the SSH key path with
<YOUR_SSH_KEY> (or <SSH_KEY_PATH>), and replace the branch name with
<PROJECT_BRANCH>; apply the same placeholder pattern to the other occurrences
noted (around lines 17, 92-96, 118) so the document is configurable for any
user.

In `@context/_build/scripts/install-from-bindep`:
- Around line 89-95: The uninstall step fails because $EXTRAS contains "-r
/output/.../requirements.txt" and pip uninstall does not accept -r; update the
branch that handles extras (the elif handling $EXTRAS) to avoid calling "$PIPCMD
uninstall -y $EXTRAS" when $EXTRAS includes an -r reference: either remove that
uninstall invocation entirely or detect when $EXTRAS contains "-r" and
skip/unroll it (e.g., parse referenced requirements files into package names
before calling $PIPCMD uninstall), keeping the subsequent "$PIPCMD install
$CONSTRAINTS $PIP_OPTS --cache-dir=/output/wheels $EXTRAS" unchanged.

In `@context/_build/scripts/introspect.py`:
- Around line 111-114: The pip_file_data helper currently follows nested
"-r"/"--requirement" includes without guarding against cycles or path escapes;
modify pip_file_data to accept and/or maintain a visited set and a root/base
directory, skip processing if new_path has already been visited to prevent
infinite recursion, and validate that new_path is inside the allowed root
(reject absolute paths or paths that escape via ..) before calling
pip_file_data(new_path); reference the pip_file_data function, the existing "if
line.startswith('-r') or line.startswith('--requirement')" branch, the path
variable, and pip_lines when implementing these checks and skips.
- Around line 76-89: get_dependency currently only rejects absolute paths but
allows path traversal like ../../outside.txt; update get_dependency to resolve
the candidate path against the collection root (use self.reference_path as the
base), normalize/abspath it (e.g., with os.path.normpath/os.path.abspath or
os.path.join + os.path.commonpath) and then verify the resolved path is inside
the collection root before returning; if the resolved path escapes the root,
raise a RuntimeError with a clear message referencing the offending path and
self.reference_path so process_collection cannot open files outside the
collection.

In `@automation/test-execution/ansible/roles/benchmark_guidellm/tasks/main.yml`:
- Around line 135-153: The task "Start GuideLLM benchmark container" currently
exposes secrets by passing env: "{{ guidellm_env }}" while no_log: false; change
the task to enable logging suppression (set no_log: true) so sensitive values
like HF_TOKEN in guidellm_env are not printed to playbook output/AWX events —
update the task that registers guidellm_container (the podman_container task
using image "{{ guidellm_cfg.container_image }}" and env "{{ guidellm_env }}")
to use no_log: true.
- Around line 33-38: The guidellm_cfg.rate value can be a scalar (from
guidellm_rate) which breaks later filters; update the set_fact that builds
guidellm_cfg so the rate is normalized to a list: take guidellm_rate_parsed |
default(guidellm_rate) | default(guidellm_cfg.rate | default([10])) and if that
value is not a sequence convert it to a single-item list (use the Jinja2 test
"is sequence" or "is iterable" and the list() filter or wrap in [value]) before
assigning to guidellm_cfg.rate so downstream join/length calls always receive a
list. Ensure you modify the set_fact block that defines guidellm_cfg (the rate
field) accordingly.
- Around line 231-246: Replace the two-task pattern that captures podman output
into the guidellm_full_logs register and then copies it to /tmp with a single
shell task that streams logs directly to disk; specifically, when
use_guidellm_container is true and container_exit_code.stdout is defined, run a
shell command that invokes podman logs for the container named ('guidellm-' ~
workload_type ~ '-' ~ core_cfg.name) and redirects its stdout/stderr to
/tmp/guidellm-{{ workload_type }}-{{ core_cfg.name }}.log, keep
args.executable=/bin/bash, set changed_when/failed_when appropriately
(false/false if you want non-failing capture), and remove the guidellm_full_logs
register and subsequent ansible.builtin.copy task.
- Around line 200-206: The task "Wait for GuideLLM benchmark to complete
(containerized)" currently only fails on rc == 124; update its failure condition
to fail on any non-zero exit code by changing failed_when to check
guidellm_exit_code_container.rc != 0 so that errors like command not found
(126/127) or other podman/timeout failures are treated as failures; keep
register guidellm_exit_code_container, changed_when: false and the existing
when: use_guidellm_container | bool unchanged.

Nitpick comments:
In `@automation/test-execution/awx/debug-guidellm-container.yml`:
- Around line 69-73: The task named "Create debug results directory" sets the
directory mode to "0777" which is world-writable; change the
ansible.builtin.file task that manages "{{ debug_results_path }}" to use a more
restrictive mode such as "0755" (or "0700" if only the running user should
write) so the debug directory isn't globally writable while still allowing the
process to write to it.
- Around line 75-81: The task "Test vLLM connectivity" uses a hardcoded HTTP URL
which triggered a static-analysis flag; update the ansible.builtin.uri url
construction to use a configurable scheme (e.g., a variable like vllm_scheme
with a sensible default) instead of literal "http", so the playbook can switch
to "https" when needed; ensure the registered variable vllm_health and
ignore_errors behavior remain unchanged and document or set vllm_scheme in
inventory/vars where appropriate.
- Around line 241-244: The cleanup task "Cleanup debug directory" currently
removes "{{ debug_results_path }}" unconditionally; change it to run only when a
boolean flag variable (e.g. cleanup_debug) is true so results can be preserved
for inspection—update the task "Cleanup debug directory" to include a when:
clause like cleanup_debug | default(true) | bool (or inverse logic per your
preferred default) and document that callers can run with -e cleanup_debug=false
to skip the removal.

In `@automation/test-execution/awx/execution-environment.yml`:
- Around line 4-6: The base image is pinned to the floating tag
"quay.io/ansible/awx-ee:latest" under images -> base_image -> name which makes
builds non-reproducible; update images.base_image.name to a specific, tested
version string (e.g., "quay.io/ansible/awx-ee:24.6.1") and ensure any other
references or deployment manifests use the same pinned tag, then run a test
build to verify compatibility.

In `@automation/test-execution/awx/Makefile`:
- Around line 300-318: The Makefile target kind-deploy-operator uses a hardcoded
sleep (sleep 10) before running kubectl wait; replace that fixed sleep with a
short polling loop that checks for the AWX CRD (or another readiness indicator)
with a small interval and an overall timeout, e.g. repeatedly run kubectl
--context=kind-$(KIND_CLUSTER_NAME) get crd <crd-name> >/dev/null && break,
sleeping 2s between attempts and failing after a configurable timeout, then
proceed to the existing kubectl wait deployment/awx-operator-controller-manager
-n awx-operator-system; update the target so the loop replaces the line with
sleep 10 and ensure it uses the same context/variables as the surrounding
commands.

In `@collections/requirements.yml`:
- Around line 1-10: Consolidate the duplicated collection constraints by
removing the duplicate manifests and making one canonical source (keep the
collections block with entries for containers.podman and ansible.posix in a
single file), update references to use that canonical file, and add a CI check
or generation step to ensure automation/test-execution/awx/requirements.yml and
context/_build/requirements.yml are derived from it; specifically, centralize
the collections: block (including name: containers.podman version:
">=1.9.0,<2.0.0" and name: ansible.posix version: ">=1.4.0,<1.6.0") into the
chosen canonical file and add CI validation/generation to prevent drift.

In `@context/_build/scripts/install-from-bindep`:
- Line 28: The shell tests and expansions use unquoted variables (e.g., the
conditional if [ -z $PKGMGR ]; then) which can break on values with spaces;
update all occurrences to quote variable expansions (e.g., use "$PKGMGR")
including the other unquoted instances noted at lines 48 and 55 so all tests and
parameter expansions in the script consistently use quoted forms.

In `@context/Containerfile`:
- Line 39: Add a short explanatory comment above the RUN line that sets
ANSIBLE_GALAXY_DISABLE_GPG_VERIFY=1 (the ansible-galaxy collection install
invocation) describing why GPG verification is disabled (e.g., using
unsigned/private/internal collections or known CI constraints) and the
associated security tradeoff, or alternatively remove the environment variable
to enable verification if all collections are signed; update the Containerfile
near the ANSIBLE_GALAXY_DISABLE_GPG_VERIFY/ansible-galaxy collection install
command accordingly.

Missing no_log on task that modifies vllm_env_vars containing HF_TOKEN.

This task combines new values into vllm_env_vars, which already contains HF_TOKEN. Without no_log, Ansible may log the merged dictionary including the token. The equivalent task in start-llm.yml (lines 167-175) includes no_log: true.

250-258: ⚠️ Potential issue | 🔴 Critical

Log fetch task will never execute - guidellm_full_logs is undefined.

The fetch task condition checks guidellm_full_logs is defined and guidellm_full_logs.stdout is defined, but this variable was removed (per the AI summary). The "Stream GuideLLM container logs directly to file" task (line 239-248) writes to /tmp/... but doesn't register guidellm_full_logs. This breaks log artifact collection.

The downstream playbook (llm-benchmark-auto.yml line 304-310) and copy-guidellm-logs.sh script expect guidellm.log to exist in results_path.

168-187: Timeout variable naming may cause precedence confusion with AWX.

AWX configuration (configure-awx.yml) passes guidellm_wait_timeout_seconds as an extra variable. Line 210 correctly uses guidellm_wait_timeout_seconds | default(guidellm_wait_timeout), so the AWX-provided value takes precedence. However, having two similarly-named timeout variables (guidellm_wait_timeout computed here vs guidellm_wait_timeout_seconds from AWX) could cause maintenance confusion.

Consider documenting this precedence or unifying the naming in a future refactor.

In @.github/workflows/build-execution-environment.yml:
- Around line 64-67: The workflow currently allows workflow_dispatch runs from
any ref to set TAGS and PRIMARY_TAG using inputs.tag (default "latest"), which
lets manual runs on non-main branches overwrite the canonical latest image;
update the conditional around github.event_name == "workflow_dispatch" so that
when handling a manual dispatch you only set PRIMARY_TAG to inputs.tag if
github.ref == "refs/heads/main" (or otherwise enforce an explicit non-latest
tag), and for non-main refs either derive a non-canonical tag (e.g., include the
branch or run id) or fail the run; adjust the logic that assigns TAGS and
PRIMARY_TAG (the lines using env.REGISTRY, env.IMAGE_NAME, and inputs.tag) to
implement this restriction.

In `@automation/test-execution/awx/configure-awx.yml`:
- Around line 146-155: The play is overwriting shared settings on the "Default"
organization by explicitly setting galaxy_credentials: [] and
default_environment: null in the awx.awx.organization task; either stop managing
those fields for the "Default" org or create/manage a dedicated organization
instead. Update the awx.awx.organization task that targets name: "Default" to
remove the galaxy_credentials and default_environment keys (leave them unset) so
org-wide defaults are preserved, or change the name to a new dedicated org and
manage those fields there.
- Around line 413-431: The DUT SSH Key credential creation is conditional (when:
ssh_key_file.stat.exists) but templates still hard-code "DUT SSH Key", breaking
the path when the key is absent; update any template/task that sets credentials
to attach "DUT SSH Key" only when ssh_key_file.stat.exists (or when the
credential actually exists) and otherwise omit the credentials entry and enable
ask_credential_on_launch; apply this change for the DUT credential usage shown
around the Create DUT SSH Credential task and the similar block referenced at
lines ~495-506 so templates rely on ask_credential_on_launch when the key file
is missing.
- Around line 53-55: The playbook currently pins project_scm_url and
project_scm_branch to a contributor fork and feature branch; update the defaults
so project_scm_url uses the canonical repository URL (instead of the contributor
fork) and project_scm_branch defaults to "main" (or alternatively derive both
from the local git remote/current branch via lookups/env vars) so fresh installs
don't sync the wrong repo or a non-existent branch—change the variables
project_scm_url and project_scm_branch accordingly (or implement lookup('env',
'GIT_REMOTE_URL')/lookup('env','GIT_BRANCH') fallback logic).
- Around line 45-48: The current defaults for controller_host and validate_certs
make insecure plain‑HTTP and disabled TLS the default; update the playbook so
controller_host defaults to a secure URL (https) or has no insecure default and
add an explicit opt‑in environment flag (e.g., CONTROLLER_INSECURE) to allow
non‑TLS for local testing; change logic around validate_certs to set false only
when that opt‑in flag is true, and reference the existing variables
controller_host and validate_certs (and the new CONTROLLER_INSECURE env var) so
callers must explicitly opt into insecure transport rather than relying on the
current unsafe defaults.
- Around line 561-569: The llm-benchmark.yml template should not prefill
required variables with sentinel strings; remove the `"REQUIRED - ..."` default
values for test_model, workload_type, and core_config_name (leave them empty or
set to null) so they are genuinely unset, and add explicit validation (e.g., an
Ansible assert in the play that checks test_model, workload_type, and
core_config_name are defined and non-empty) to fail fast if the user doesn’t
supply real values; update references to test_model, workload_type, and
core_config_name in llm-benchmark.yml accordingly.

In `@automation/test-execution/awx/Makefile`:
- Around line 258-287: The check-kind-requirements Makefile target should also
verify Ansible prerequisites so failures surface before expensive cluster work:
add a check in check-kind-requirements to ensure the ansible-playbook command is
present (fail with an informative message if missing) and add a check that the
awx.awx Ansible collection is available (e.g., run ansible-galaxy collection
list and verify awx.awx is listed, or attempt ansible-galaxy collection install
awx.awx with --no-deps as a fallback) so that kind-configure (which runs
ansible-playbook configure-awx.yml) and the kind-quickstart flow will abort
early if Ansible or the awx.awx collection are not installed.

In `@context/_build/scripts/install-from-bindep`:
- Line 28: The emptiness check for the PKGMGR variable uses an unquoted
expansion in the conditional (the if [ -z $PKGMGR ] test), which can fail for
empty/whitespace/glob values; fix it by modifying the conditional that checks
PKGMGR to use a quoted variable expansion (i.e., quote the PKGMGR expansion in
the -z test) so the shell test behaves correctly for all values.

In `@context/_build/scripts/introspect.py`:
- Around line 116-121: The function read_req_file prints a warning when the
requirements file is missing but then proceeds to open(path) causing a
FileNotFoundError; update read_req_file to stop after the existence check by
either returning a sensible default (e.g., empty string) or raising a clear
exception — replace the print-only branch with an early return or raise
FileNotFoundError with a descriptive message so the subsequent with open(path,
'r') as f: return f.read() is only executed when os.path.exists(path) is True.
- Around line 90-108: The path-traversal check uses
os.path.dirname(self.reference_path) which moves one directory up and weakens
the validation; replace that so collection_root is set to self.reference_path
(not its dirname), then compute abs_collection_root =
os.path.abspath(collection_root) and validate abs_candidate_path against that
abs_collection_root as currently done (keeping candidate_path,
abs_candidate_path and is_inside logic). Ensure you remove the dirname call and
keep the rest of the checks (path_prefix, startswith or equality) so ../ escapes
are correctly rejected.

Nitpick comments:
In @.github/workflows/build-execution-environment.yml:
- Around line 25-30: The workflow lacks a concurrency policy for the
build-and-push job which can cause race conditions when pushing mutable tags;
add a concurrency block under the job named build-and-push using the YAML key
concurrency with a group that includes the current ref (e.g. use the expression
referencing github.ref or combine github.workflow and github.ref) and set
cancel-in-progress to true so older runs on the same ref are cancelled.

In `@automation/test-execution/ansible/roles/benchmark_guidellm/tasks/main.yml`:
- Around line 168-187: The computed timeout variable guidellm_wait_timeout can
be confused with the AWX-provided guidellm_wait_timeout_seconds; rename the
computed set_fact key to guidellm_wait_timeout_seconds (replace
guidellm_wait_timeout in the ansible.builtin.set_fact block) so the AWX
extra-var can directly override it, and update any local references that
currently use guidellm_wait_timeout (including places that call
guidellm_wait_timeout_seconds | default(guidellm_wait_timeout)) to remove the
default fallback or point to the new unified name; ensure the calculation logic
and the min cap (14400) remain unchanged.

In `@context/_build/scripts/install-from-bindep`:
- Around line 75-77: The current loop "for extra in $*; do" builds EXTRAS via
string concatenation which is brittle; change it to iterate over "$@" and
collect "-r" "/output/$extra/requirements.txt" pairs into a shell array (e.g.,
EXTRAS_ARRAY) instead of a plain string, then use that array expansion
("${EXTRAS_ARRAY[@]}") where EXTRAS is consumed; update the other similar sites
that build extras (the other EXTRAS usages around the referenced block) to
follow the same "$@" + array pattern to avoid word-splitting and globbing
issues.

175-187: ⚠️ Potential issue | 🟠 Major

Timeout override contract is being overwritten.

Line 175 always recalculates guidellm_wait_timeout_seconds, so explicit overrides (and legacy guidellm_wait_timeout callers) are ignored. That breaks documented/custom safety-timeout control and can cause premature timeout failures on long workloads.

59-73: ⚠️ Potential issue | 🟠 Major

core_sweep_counts is accepted but still not executable in this workflow.

Line 63-64 allows sweep-only input, but each phase imports llm-benchmark-auto.yml without materializing requested_cores per run; that imported playbook still asserts requested_cores must exist, so sweep-only invocations fail at runtime. Either iterate core_sweep_counts into per-phase runs with requested_cores, or fail fast here and redirect users to llm-core-sweep-auto.yml.

67-75: ⚠️ Potential issue | 🟠 Major

workflow_dispatch still permits publishing :latest from non-main refs.

At Line 69, only main + latest is handled specially; the else branch (Line 73-75) still publishes inputs.tag verbatim, so a non-main manual run with default latest can overwrite the canonical tag.

Suggested fix
           if [ "${{ github.event_name }}" = "workflow_dispatch" ]; then
-            # Only allow 'latest' tag on main branch

Inline comments:
In `@automation/test-execution/ansible/llm-benchmark.yml`:
- Line 122: The benchmark artifacts path was changed to use
hostvars['localhost']['local_results_base'] (see the path expression using
test_model and core_configuration.name) but log_collection_dest and the summary
path still point to the hardcoded results/llm, causing artifacts to be split;
update the log collection destination variable (log_collection_dest) and the
summary path to derive from the same hostvars['localhost']['local_results_base']
+ the same subpath pattern ({{ test_model | replace('/', '__') }}/{{
workload_type }}-{{ test_run_id }}/{{ core_configuration.name }}) so all steps
(artifact path, log_collection_dest, and summary) reference the same base and
folder structure.

In `@automation/test-execution/ansible/roles/benchmark_guidellm/tasks/main.yml`:
- Around line 239-242: The task "Stream GuideLLM container logs directly to
file" writes logs to a static /tmp filename which can collide; update the
ansible task's shell command (the podman logs invocation that creates
/tmp/guidellm-{{ workload_type }}-{{ core_cfg.name }}.log) to append a unique
identifier such as {{ test_run_id }} (or another unique suffix) to the filename
(e.g. /tmp/guidellm-{{ workload_type }}-{{ core_cfg.name }}-{{ test_run_id
}}.log) and then update any downstream steps that fetch or reference that file
to use the same composed name so concurrent runs do not overwrite each other.

In `@automation/test-execution/awx/configure-awx.yml`:
- Around line 82-83: The default for default_guidellm_rate is currently the
string "'[1]'", which can propagate as a string; change it to a real list and
ensure env values are parsed as YAML: replace the value for
default_guidellm_rate so the default is an actual list (e.g., use default([1],
true)) or use from_yaml to parse the env value (for example wrap
lookup('env','GUIDELLM_RATE') with | default('[1]', true) | from_yaml); update
the same pattern where guidellm_rate is forwarded. Also ensure
default_guidellm_wait_timeout remains a scalar (no change) but apply the list
fix to any other occurrences mentioned (lines around guidellm_rate forwarding).
- Around line 485-498: The "Create DUT SSH Credential" Ansible task using
awx.awx.credential is sending raw private key material via inputs.ssh_key_data
and lacks no_log, risking secret exposure; update this task to set no_log: true
on the task and ensure any registered variables like ssh_key_content are also
treated as sensitive (avoid printing or registering without no_log) so the
private key is not shown in AWX/job output, and keep the when:
ssh_key_file.stat.exists condition intact.
- Around line 594-597: Fallback image ee_image_name currently hardcodes
"vllm-awx-ee:latest" which is likely local-only; change the set_fact for
ee_image_name (the block using ee_image_detected and is_kind) to use a
registry-pullable default and allow an environment override (e.g., read a
DEFAULT_EE_IMAGE / AWX_EE_IMAGE env var or an AWX variable) instead of the
local-only tag so non-KIND/external AWX can pull the EE; update the conditional
fallback expression to prefer the detected value, then the env/variable
override, and finally a registry-backed default image name.

In `@automation/test-execution/awx/execution-environment.yml`:
- Line 6: Replace the mutable image tag under the name key in
execution-environment.yml (currently "quay.io/ansible/awx-ee:latest") with a
pinned, immutable reference: either a specific released tag (e.g.,
:<major>.<minor>.<patch>) or the image digest form (`@sha256`:<digest>); update
the "name" value to that pinned tag so builds are deterministic and
reproducible, and document the chosen version/digest in the PR description.

In `@automation/test-execution/awx/Makefile`:
- Around line 355-360: Remove the erroneous hardcoded build-arg "--build-arg
PYCMD=/usr/bin/python3.12" from the ansible_builder build invocations (the lines
that run "python3 -m ansible_builder build ... --build-arg
PYCMD=/usr/bin/python3.12"); either drop the PYCMD override entirely so the
Dockerfile/default ARG is used, or replace it with the correct path
"/usr/local/bin/python3.11" if you need an explicit override, and ensure both
occurrences of that build command are updated consistently.

In `@context/_build/scripts/introspect.py`:
- Around line 169-178: The current parsing of requirement directives fails when
a line beginning with '-r' or '--requirement' lacks a filename because "_,
new_filename = line.split(None, 1)" assumes two parts; update the logic in the
block handling "if line.startswith('-r') or line.startswith('--requirement')" to
first check the split result (or handle ValueError) and if no filename is
present either skip the line or raise a clear RuntimeError mentioning the
offending "line" and "path"; ensure you still use "abs_path" and "new_filename"
(when present) and keep the existing absolute-path rejection that uses
os.path.isabs(new_filename).

In `@context/Containerfile`:
- Line 22: The Docker RUN step downloads and builds Python-3.11.9.tgz without
verifying integrity; update the Containerfile to fetch the corresponding
checksum or GPG signature (e.g., Python-3.11.9.tgz.sig or SHA256SUMS), verify
the downloaded Python-3.11.9.tgz before extracting (fail the build if the
checksum/signature does not match), and only proceed to tar xzf, ./configure,
make, and make altinstall after successful verification so the build aborts on
mismatch.
- Line 40: Remove the GPG verification bypass by deleting the environment
variable assignment ANSIBLE_GALAXY_DISABLE_GPG_VERIFY=1 from the RUN that
invokes ansible-galaxy collection install (the command starting with
"ansible-galaxy collection install $ANSIBLE_GALAXY_CLI_COLLECTION_OPTS -r
requirements.yml --collections-path \"/usr/share/ansible/collections\""); leave
the rest of the RUN intact so collections are installed with default GPG
verification enabled.

96-101: ⚠️ Potential issue | 🟠 Major

Missing early return causes FileNotFoundError after warning.

The function prints a warning when the file doesn't exist (line 99) but then proceeds to open(path) on line 100, which will raise FileNotFoundError. This was flagged in a past review as addressed, but the code still shows the same pattern.

 def read_req_file(path):
     """Provide some minimal error and display handling for file reading"""
     if not os.path.exists(path):
-        print(f'Expected requirements file not present at: {os.path.abspath(path)}')

Path traversal validation only blocks absolute paths.

get_dependency rejects absolute paths but still allows relative path traversal like ../../outside.txt. A collection could declare such a path, and process_collection() would open it during the EE build. Consider resolving the path and validating it stays under the collection root.

This was flagged in a past review as addressed but the current code doesn't include the fix.

165-168: apt-key add is deprecated.

The Trivy installation uses the deprecated apt-key add method. While the continue-on-error: true handles failures gracefully, consider updating to the modern signed-by approach for future-proofing:

Updated configure-awx.yml to automatically discover and import all
playbooks from automation/test-execution/ansible/ directory:
- Finds all .yml files in the ansible directory
- Creates job template for each playbook with auto-generated name
- Excludes hosts.yml (inventory file)
- Shows list of imported templates in completion message

This eliminates the need to manually maintain job template definitions
and ensures all playbooks are immediately available in AWX.

macOS now uses externally-managed Python environments (PEP 668).

Updated pip installation logic to handle strict macOS Python environments:
- Try --user --break-system-packages first (safest combo for macOS)
- Fall back to --user only
- Continue with warning if installation fails (non-blocking)
- Verify actual availability after installation attempt
- Applied to both openshift and podman-compose installations

This allows the setup to proceed even if pip installations fail,
with clear warnings about potential issues in later steps.

Updated AWX operator deployment to use official release manifest
instead of cloning and using kustomize:
- Use https://raw.githubusercontent.com/ansible/awx-operator/2.20.0/deploy/awx-operator.yaml
- Remove dependency on awx-operator git clone
- Add namespace creation for awx
- Update operator namespace reference to awx-operator-system
- Increase timeout to 180s for operator readiness

- Clone awx-operator v2.19.1 (latest stable release)
- Use 'make deploy' from operator repo (handles kustomize correctly)
- Removed broken URL-based deployment attempts
- Keep awx-operator-system namespace reference

- Setting kubectl context to kind-awx before deployment
- Using kubectl apply directly instead of operator's make deploy
- Explicitly set KUBECONFIG environment variable
- Use config/default kustomize directory

This ensures the operator deploys to the correct cluster.

Moved bench_config from individual load generator host to
load_generator group level:
- vllm_host now automatically references DUT's ansible_host via Jinja2
- Eliminates confusing duplication of vLLM hostname
- Load generator host only defines connection details
- bench_config in group vars applies to all load generators

…ompatibility

When using Podman with KIND, images are tagged with localhost/ prefix
(localhost/vllm-awx-ee:latest), but with Docker they have no prefix
(vllm-awx-ee:latest). This causes ImagePullBackOff errors when AWX
tries to create automation job pods.

Solution:
- Detect container runtime in KIND cluster (podman vs docker/containerd)
- Use localhost/vllm-awx-ee:latest for Podman
- Use vllm-awx-ee:latest for Docker
- Fallback to vllm-awx-ee:latest if detection fails

This fixes the "Failed to JSON parse a line from worker stream" error

In KIND environments with DNS issues, project sync fails and playbooks
are not cloned. Job template creation would then fail with "Playbook
not found for project" errors.

Since projects have scm_update_on_launch: true, playbooks will sync
automatically when jobs are launched. Make job template creation
non-blocking (failed_when: false) so configuration completes even if
playbooks aren't available yet.

   - Properly handles results when failed_when: false is used

2. Improved execution environment image name detection for Podman
   - Detect if running in KIND cluster
   - Query actual images in KIND node to determine prefix
   - Use localhost/ prefix if image exists with that prefix
   - Display detected image name for debugging
   - Dynamically get node name instead of hardcoding

Added comprehensive troubleshooting section for DNS resolution failures
when running KIND clusters on Linux systems with firewalld.

The issue occurs because firewalld's docker zone blocks outbound DNS

- Symptoms to identify the issue (ImagePullBackOff, DNS timeouts)
- Root cause explanation
- Diagnostic commands to verify the problem
- Step-by-step fix with firewall-cmd
- Recovery steps for failed pods
- Platform-specific note (Linux/firewalld only)

This is documented rather than automated because it:
- Requires sudo/root privileges
- Is a system-level configuration users should be aware of
- Only applies to specific platforms (not macOS, not all Linux distros)

Added automatic CoreDNS configuration on Linux to fix DNS resolution
issues in KIND clusters. CoreDNS now forwards queries directly to the
host's DNS servers instead of using Docker's embedded DNS proxy.

Changes:
- Added `kind-fix-coredns-dns` target that:
  - Detects Linux platform (skips on macOS)
  - Extracts nameservers from /etc/resolv.conf
  - Patches CoreDNS ConfigMap with host DNS servers
  - Falls back to Google DNS (8.8.8.8, 8.8.4.4) if no nameservers found
  - Restarts CoreDNS to apply changes
- Integrated into `kind-deploy-awx` workflow (runs automatically)
- Updated README troubleshooting section to document:
  - Automatic CoreDNS configuration
  - One-time firewall setup (still manual)
  - Clear separation between automatic and manual steps

Root cause: Docker's embedded DNS at 172.18.0.1:53 was unreachable
from KIND pods, causing DNS timeouts. Direct forwarding to host DNS
servers bypasses this issue.

This fix is applied automatically on every cluster creation, so DNS
"just works" after the one-time firewall configuration.

AWX was failing with HTTP 500 errors when creating inventory hosts/groups
because instances were configured as 'control' nodes (API only) instead of
'hybrid' nodes (API + execution). When adding hosts/groups, AWX queues a
background task to update computed fields, which requires execution capacity.

Added task to automatically configure all AWX instances as hybrid nodes
during playbook execution, ensuring background tasks can be processed.

Changed from deployment/awx-postgres-15 to awx-postgres-15-0 to match
the actual StatefulSet pod name. The previous command was failing silently,
preventing AWX instances from being configured as hybrid nodes.

Resolve Python version conflicts in AWX EE build by compiling Python 3.11
from source instead of using dnf packages. The base AWX EE image has
Python 3.12 (with Ansible) and Python 3.9 (system default), causing
package manager conflicts when trying to install python3.11 packages.

Changes:
- Install build dependencies and compile Python 3.11.9 from source
- Configure dynamic linker to find Python 3.11 shared libraries
- Use Python 3.11 for custom package installations
- Keep Python 3.12 for Ansible/Ansible Runner compatibility
- Add proper build exit code handling in Makefile
- Update user documentation for benchmark results location

This allows the execution environment to successfully install packages
requiring Python 3.11 while maintaining compatibility with the AWX
operator's Ansible installation.

…lections

- Add SHA256 checksum verification for Python 3.11.9 source download
  to protect against MITM attacks and file corruption
- Remove ANSIBLE_GALAXY_DISABLE_GPG_VERIFY=1 to enable cryptographic
  verification of Ansible Galaxy collections
- Build now fails immediately if checksum or signature verification fails

These changes prevent supply chain attacks and ensure only verified
software is included in the execution environment.

Update workflow to reject manual runs from non-main branches that attempt
to use the 'latest' tag, preventing accidental overwrites of the canonical
production image.

- On main branch: Allow any tag including 'latest'
- On non-main branches: Reject 'latest', require explicit custom tags
- Provides clear error message guiding users to use custom tags

This prevents supply chain confusion and ensures latest always points to
verified main branch builds.

- Fix Makefile build arguments to use correct Python 3.11 path
  (/usr/local/bin/python3.11 instead of non-existent /usr/bin/python3.12)
- Pin AWX EE base image to version 24.6.1 for reproducible builds

These changes ensure builds use the correct Python installation that
matches what the Containerfile builds from source, and prevent unexpected
breakage from upstream base image changes.

Multiple improvements to make AWX configuration more reliable and secure:

- Add no_log protection to SSH key reading and credential creation tasks
  to prevent private keys from appearing in AWX job logs
- Parse guidellm_rate as YAML list instead of string to prevent type errors
  in downstream tasks that expect list iteration
- Use registry-pullable default EE image with AWX_EE_IMAGE env override
  instead of local-only tag for external AWX deployments
- Show conditional credential status in summary message to accurately
  reflect whether SSH key was configured

- Add test_run_id to GuideLLM log filenames to prevent collisions when
  multiple concurrent benchmark runs use the same workload/core config
- Add validation for malformed requirement directives in introspect.py
  to fail with clear error messages instead of cryptic ValueError

These changes prevent race conditions in concurrent testing and make
build failures easier to diagnose.

Update execution environment to build Python 3.12.8 from source with
proper integrity verification.

Changes:
- Build Python 3.12.8 from source with SHA256 checksum verification
- Update Makefile to use /usr/local/bin/python3.12
- Correct checksum: 5978435c479a376648cb02854df3b892ace9ed7d32b1fead652712bee9d03a45

This resolves Python version compatibility issues while maintaining
security through cryptographic verification of the source tarball.

Replace brittle string concatenation with proper shell array handling
to avoid word-splitting and globbing issues.

Changes:
- Use "$@" instead of $* to properly preserve arguments
- Collect extras into EXTRAS_ARRAY instead of string concatenation
- Use "${EXTRAS_ARRAY[@]}" for safe array expansion
- Check array length with ${#EXTRAS_ARRAY[@]}
- Add comment explaining why uninstall is skipped for extras

This prevents issues with filenames containing spaces or special
characters and makes the script more robust.

All result paths now consistently use hostvars['localhost']['local_results_base']
to prevent artifacts from being split across different directories.

Changes:
- Update log_collection_dest to use local_results_base instead of hardcoded path
- Update summary results path to use local_results_base
- Ensures artifacts, logs, and summaries all go to the same location

This fixes path inconsistency between AWX runs (~/benchmark-results) and
local runs (results/llm) by using the centralized variable.

Revert to using the AWX EE base image's Python 3.9 which already has
Ansible and Ansible Runner installed, instead of building Python 3.12
from source which causes Ansible check failures.

Changes:
- Remove Python 3.12 build steps from execution-environment.yml and Containerfile
- Update Makefile to use /usr/bin/python3 (Python 3.9)
- Remove ANSIBLE_GALAXY_DISABLE_GPG_VERIFY=1 to enable GPG verification
- Verified successful build with Python 3.9 test

This resolves the "Missing Ansible or Ansible Runner" error while
maintaining all security improvements.

Modify the build-execution-environment workflow to:
- Build the execution environment on pull requests with Containerfile changes
- Only push to Quay.io registry when merged to main branch
- Skip login, tag, push, verify, and scan steps on PRs
- Update build summary to indicate PR validation vs. main push

This allows PR validation without publishing images, while ensuring
only merged changes push to the registry.
