AnsibleFest 2017 Demo

This project includes all the elements required to run the demo.

Requirements

The following are required to run this demo

  • Docker 17.03.1
  • Ansible 2.3.2.0 (Installed via Pip)
  • Python 2.7.13
  • jq 1.5.2

It's been tested on OSX. It should work on other operating systems, but I have not tested it.

Setup

To begin, clone this repository and step into the folder.

Start the Cluster

To begin, fire up the cluster, which includes Conjur, Postgres, CLI, 2 Staging Containers, and 4 production servers:

$ ./demo.sh

To exit, ctr-c

Load Policy

Load the full policy, users, and groups from the /policy folder:

$ ./1_load_policies.sh

Set Secrets

Load values into our variables:

$ ./2_set_secrets.sh

Ansible

There is a single deploy.sh file responsible for deploying to the Staging or Production environment.

This script does the following:

  1. Generate a Host Factory token for that particular environment
  2. Uses cyberark/ansible-role-conjur role to:
  • Provide identity to the remote instance
  • Add them to the correct layer based on the provided Host Factory token.
  1. Retrieve secrets using the identity of that machine.

To perform the above steps on the staging environment:

$ ./deploy.sh staging

To perform the above steps on the production environment:

$ ./deploy.sh production

Scaling Production Nodes

To demonstrate the simplicity of scaling up using Host Factory tokens, scale production nodes from 4 to 20:

$ docker-compose scale myapp_production=20

Next, in the ansible/inventory file, change the line: ansiblefest_myapp_production_[1:4] to ansiblefest_myapp_production_[1:20] and save the file.

Then, re-run the production configuration:

$ ./deploy.sh production

View Application Containers

Docker Compose handles the port mapping, binding each container to localhost. To pull the app on a browser, you'll need to pass the docker-compose assigned port. You can get this port by viewing the running containers:

$ docker ps
CONTAINER ID        IMAGE                        COMMAND                  CREATED             STATUS              PORTS                            NAMES

For the above example, the first container (37881ae9a161), can be viewed on port 32833: 0.0.0.0:32833->4567/tcp. This container is accessible via:

http://localhost:32833
