This manual documents the various `group_vars` configuration options for the `pvc-ansible` framework.
|
This manual documents the various `group_vars` configuration options for the `pvc-ansible` framework. We assume that the administrator is generally familiar with Ansible and its operation.
|
||||||
|
|
||||||
|
## General usage
|
||||||
|
|
||||||
|
### Initial setup
|
||||||
|
|
||||||
|
After cloning the `pvc-ansible` repo, set up a set of configurations for your cluster. One copy of the `pvc-ansible` repository can manage an unlimited number of clusters with differing configurations.
|
||||||
|
|
||||||
|
All files created during initial setup should be stored outside the `pvc-ansible` repository, as they will be ignored by the main Git repository by default. It is recommended to set up a separate folder, either standalone or as its own Git repository, to contain your files, then symlink them back into the main repository at the appropriate places outlined below.
|
||||||
|
|
||||||
|
Create a `hosts` file containing the clusters as groups, then the list of hosts within each cluster group. The `hosts.default` file can be used as a template.
|
||||||
|
|
||||||
|
Create a `files/<cluster>` folder to hold the cluster-created static configuration files. Until the first bootstrap run, this directory will be empty.
|
||||||
|
|
||||||
|
Create a `group_vars/<cluster>` folder to hold the cluster configuration variables. The `group_vars/default` directory can be used as an example.
|
||||||
|
|
||||||
|
### Bootstrapping a cluster
|
||||||
|
|
||||||
|
Before bootstrapping a cluster, see the section on [PVC Ansible configuration variables](/manuals/ansible#pvc-ansible-configuration-variables) to configure the cluster.
|
||||||
|
|
||||||
|
Bootstrapping a cluster can be done using the main `pvc.yml` playbook. Generally, a bootstrap run should be limited to the coordinators of the cluster to avoid potential race conditions or strange bootstrap behaviour. The special variable `bootstrap=yes` must be set to indicate that a cluster bootstrap is to be requested.
|
||||||
|
|
||||||
|
**WARNING:** Do not run the playbook with `bootstrap=yes` *except during the very first run against a freshly-installed set of coordinator nodes*. Running it against an existing cluster will result in the complete failure of the cluster, the destruction of all data, or worse.
|
||||||
|
|
||||||
|
### Adding new nodes
|
||||||
|
|
||||||
|
Adding new nodes to an existing cluster can be done using the main `pvc.yml` playbook. The new node(s) should be added to the `group_vars` configuration `node_list`, then the playbook run against all hosts in the cluster with no special flags or limits. This will ensure the entire cluster is updated with the new information, while simultaneously configuring the new node.
|
||||||
|
|
||||||
|
### Reconfiguration and software updates
|
||||||
|
|
||||||
|
After modifying configuration settings in the `group_vars`, or to update PVC to the latest version on a release, deployment of updated cluster can be done using the main `pvc.yml` playbook. The configuration should be updated if required, then the playbook run against all hosts in the cluster with no special flags or limits.
|
||||||
|
|
||||||
|
## PVC Ansible configuration variables
|
||||||
|
|
||||||
|
The `group_vars` folder contains configuration variables for all clusters managed by your local copy of `pvc-ansible`. Each cluster has a distinct set of `group_vars` to allow different configurations for each cluster.
|
||||||
|
|
||||||
|
This section outlines the various configuration options available in the `group_vars` configuration; the `group_vars/default` directory contains an example set of variables, split into two files (`base.yml` and `pvc.yml`), that set every listed configuration option.
|
||||||
|
|
||||||
|
#### Conventions
|
||||||
|
|
||||||
|
* Settings may be *required*, `optional`, or `ignored`. Ignored settings are used for human-readability in the configuration but are ignored by the actual role.
|
||||||
|
|
||||||
|
* Settings may `depends` on other settings. This indicates that, if one setting is enabled, the other setting is very likely *required* by that setting.
|
||||||
|
|
||||||
|
* If a particular `<setting>` is marked `optional`, and a latter setting is marked `depends on <setting>`, the latter is ignored unless the `<setting>` is specified.
