deploy_cluster:

• easily deploy corosync/pacemaker clusters
• automate deploying clusters in a replicable manner
• functionally test Pacemaker Resource Agents by making it easier to write close-to-real-life tests

The tool includes classes that deploy clusters with highly-available Postgresql using a multi-state Pacemaker resource agent.

There are some unit tests and functional tests, but more tests are needed to confirm the RA works properly in most scenarios. This tool makes it easier to write such functional tests.

Requirements

• Linux or Windows as the VM host

• Python >= 3.6 with module Paramiko:

  python -m pip install paramiko
  

• VirtualBox

• pgha.py

Usage

1. Set up a VirtualBox VM that has:

   • CentOS/RHEL 7, Debian 9, or Ubuntu Zesty
   • SELinux disabled
   • VirtualBox guest additions
   • Postgresql 9.6 or 10
   • pcs enabled (disable corosync and pacemaker services)
   • Enable root account (when using Ubuntu)

2. Export the VM as an OVA file

3. Update the JSON cluster file as needed (config/pgha_cluster.json)

   • Set the path to pgha.py
   • Set hosts and IP addresses
   • ...

4. Deploy the cluster:

   python src/pgha_deployer.py config/pgha_cluster.json
