Ansible Role for Patroni

This is an Ansible role that installs and sets up Patroni, which is a high availability (HA) solution for PostgreSQL databases.

Help Needed! If you run into any problems while using this role, find bugs, notice missing features, or have suggestions for improvements, please let us know by reporting an issue.

Requirements

This role needs root access, so make sure to tell Ansible to use become: true in a way that works for you. You can find more about this here.

Role Variables

More information coming soon.

Dependencies

The role has no specific dependencies, but Patroni requires a Distributed Configuration Store (DCS), such as Etcd, Consul, ZooKeeper, or Exhibitor, to be installed and properly configured. It's your responsibility to ensure the DCS is ready to use before running this role. If you haven't set up a DCS, you can use one of the following roles (just uncomment the related section here and set the variable patroni_dcs_exists to false):

• andrewrothstein.etcd-cluster
• brianshumate.consul
• AnsibleShipyard.ansible-zookeeper
