Playbook - ceph.yml

Setup a Ceph StorageClass on a Kubernetes cluster.

This playbook wraps the role ceph_client_k8s in two steps:

  • Gather the Ceph cluster information
  • Build and install a RBD StorageClass from the gathered information

This playbook uses two groups from the provided inventory(ies):

  • A Ceph cluster / mons nodes with the group ceph_mons
  • A Kubernetes cluster / master nodes with the group k8s_masters

The Ceph cluster information are automatically gathered by the role ceph_client_k8s (from the tasks file ceph_facts.yml), if and only if at least one host is given in the ceph_mons group.

You have three options when calling the playbook to setup the StorageClass:

  • Provide two inventories to Ansible when calling the playbook (one for K8S and another for Ceph: ansible-playbook -i <../inventories/k8s> -i <../inventories/ceph> playbooks/ceph.yml --tags [...]
  • Provide the Ceph cluster facts as variables. See the role ceph_client_k8s documentation for the required variables.
  • Add the Ceph cluster nodes in you K8S inventory. This is not a good solution for Ceph clusters hosted out of K8S.
