Joshua Boniface 934f73af0f Support using existing SSL certs on system 
Add the additional pvc_api_ssl_cert_path and pvc_api_ssl_key_path
group_vars options, which can be used to set the SSL details to existing
files on the filesystem if desired. If these are empty (or nonexistent),
the original pvc_api_ssl_cert and pvc_api_ssl_key raw format options
will be used as they were.

Allows the administrator to use outside methods (such as Let's Encrypt)
to obtain the certs locally on the system, avoiding changes to the
group_vars and redeployment to manage SSL keys.

PVC Ansible

NOTICE FOR GITHUB: This repository is a read-only mirror of the PVC repositories from my personal GitLab instance. Pull requests submitted here will not be merged. Issues submitted here will however be treated as authoritative.

A set of Ansible roles to set up PVC nodes. Part of the Parallel Virtual Cluster system.

Tested on Ansible 2.2 through 2.8; 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.

This role is optional; the administrator may configure the base system however they please so long as the pvc role can be installed thereafter.

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.
