1.1.0-RC2

Merge pull request #1213 from ksatchit/v1.1.x

[Cherry-pick for RC2]

1.1.0-RC1

(feat): Adding openebs control plane pod delete experiment (#1203)

Signed-off-by: Raj <[email protected]>

1.0.1

New features and Enhancements

• Adds ramp time (warm-up period before chaos is injected) support to the generic chaos experiments
• Optimises the chaosServiceAccount permissions needed for current OpenEBS experiments
• Improved negative path/error handling in container-kill experiment
• Support for containerd runtime in OpenEBS chaos experiments
• Improve OpenEBS network loss experiments to use iSCSI session recovery timeout as default loss period with data persistence verification as post-chaos checks

1.0.0

New features and Enhancements

• Introduces a new chart for CoreDNS, a graduated CNCF project with a DNS pod failure experiment.
• Enhances the infrastructure/cluster level chaos suite with node drain chaos experiment
• Enhances the pod network chaos suite with network packet corruption chaos experiment
• Enhances the resource stress chaos suite with pod/container CPU hog experiment
• Supports post chaos checks against multiple (dependent) applications via the auxiliaryAppInfo property in the ChaosEngine CR
• Optimises the chaosServiceAccount permissions needed for each experiment at their respective scope (Namespaced, Cluster) in the scope & permissions of the ChaosExperiment CR. A sample RBAC manifest is now also provided with individual experiment documentation
• Adds validation of LitmusChaos CRDs via OpenAPI schema validation to help with prevention of malformed - ChaosEngine/ChaosExperiment CRs
• Upgrades the new Go ChaosRunner to beta quality
• Adds Gitlab CI for build & Chaos-Chart-e2e pipelines on LitmusChaos repositories
• Enhances the side panel on charthub (hub.litmuschaos.io) with experiment maturity, documentation link & supported Kubernetes platforms
• Includes support for usage (Google Analytics) metrics against the Chaos Experiments to capture chaos trends, indicated on respective charts in the charthub
• Indicates blast radius of a Chaos Experiment on the respective Charts in the charthub

Major Bug Fixes

• Fixes chaoslib task files to successfully cleanup chaos resources (daemonsets) in case of infra chaos experiments
• Fixes chaoslib task files to end plays/experiment upon not meeting expected conditions/results rather than notify & proceed with play.
• Move to apps/v1 for deployment/daemonset resources to support recent Kubernetes versions (1.16+)
• Fixes inability to cleanup experiment job when .spec.jobCleanupPolicy is set to delete with Go chaos runner
• Fixes reuse of facts/ playbook, included & registered variables by setting up a new naming convention to pass details from experiment logic playbooks to task files
• Update the docs with correct values for Mandatory/Optional nature of experiment environmental variables
• Fix broken/dead links on the charthub and docs

Community

• Monthly community sync-up (every 3rd Wednesday) to go over the concluded release, roadmap discussion, contributor shoutout, presentations/demos
