PVC Ansible

A set of Ansible roles to set up a PVC node host. Tested on Ansible 2.2 through 2.6; it is not guaranteed to work properly on older or newer versions.

Roles

This repository contains two roles:

base

This role provides a standardized and configured base system for PVC. This role expects that the system was installed via the PVC installer ISO, which results in a Debian Buster system.

pvc

This role configures the various subsystems required by PVC, including Ceph, Libvirt, Zookeeper, FRR, and Patroni, as well as the main PVC components themselves.

Variables

A default example set of configuration variables can be found in group_vars/default/.

A full explanation of all variables can be found in the manual.

Using

NOTE: These roles expect a Debian 10.X (Buster) system specifically. This is currently the only operating environment supported for PVC.

NOTE: All non-default directories under group_vars/ and files/, and the hosts file, are ignored by this Git repository. It is advisable to manage these files securely in a separate repository and use symlinks to place them in the expected locations in this repository. Note that the files/ data is created during cluster bootstrap.

For full details, please see the general PVC install documentation.

  1. Deploy a set of 3 or 5 initial PVC nodes using the PVC install ISO.
  2. Create a new cluster group in the hosts file, using hosts.default as an example. For the initial bootstrap run, it is recommended to only include the initial coordinators to ensure a smooth bootstrapping.
  3. Create a set of vars in group_vars, using group_vars/default as an example. Ensure that all desired coordinators are configured with the is_coordinator: yes flag.
  4. Run the pvc.yml playbook against the servers. If this is the very first run for a given cluster, use the -e bootstrap=yes variable to ensure the Ceph, Patroni, and PVC clusters are initialized.
