Usage

Role Variables

Some variables available in this role are listed here. The full set is defined in [defaults/main.yml](defaults/main.yml).

microceph_version: Version to utilize, defaults value is latest/edge.
microceph_cluster_nodes: Hostgroup whose members will form ceph cluster
microceph_seed_node: Node name that will be used to start cluster formation
microceph_encrypt_data: Encrypt all the data in the microceph drive at rest see : Full disk encryption
microceph_disk_devices: List of all the devices the role should add as osds once the nodes join. Make sure they exist prior otherwise the playbook will skip.

Playbook example

- hosts: servers
  roles:
    - role: pitabwire.microceph
      vars:
        microceph_cluster_nodes: ceph_nodes
        microceph_seed_node: ceph-node-1
        microceph_encrypt_data: False

Increasing data nodes

Additional nodes to the cluster can be added at any time. All nodes in the microceph_cluster_nodes hostgroup will run microceph cluster join <join token>, more info on this can be found here: microceph join non primary node.

Testing

Using Molecule wrapper and system Python

./moleculew lint
./moleculew create
./moleculew list
./moleculew check
./moleculew test

Using Python virtual environment

Set up virtual environment
```
$ python3 -m venv venv
```
Activate the environment
```
$ . venv/bin/activate
```

Install Molecule with lint and Docker options

$ pip install molecule molecule-plugins[vagrant]

Install up-to-date Ansible package if necessary
```
$ pip install ansible
```
Run the test commands:
- molecule lint
- molecule create
- molecule list
- molecule check
- molecule test
