1.3. Additional resources

The /usr/share/openstack-tripleo-heat-templates/environments/ceph-ansible/ceph-ansible.yaml environment file instructs the director to use playbooks derived from the ceph-ansible project. These playbooks are installed in /usr/share/ceph-ansible/ of the undercloud. In particular, the following file contains all the default settings that the playbooks apply:

  • /usr/share/ceph-ansible/group_vars/all.yml.sample
警告

Although ceph-ansible uses playbooks to deploy containerized Ceph Storage, do not edit these files to customize your deployment. Instead, use heat environment files to override the defaults set by these playbooks. If you edit the ceph-ansible playbooks directly, your deployment fails.

For information about the default settings applied by director for containerized Ceph Storage, see the heat templates in /usr/share/openstack-tripleo-heat-templates/deployment/ceph-ansible.

注記

Reading these templates requires a deeper understanding of how environment files and heat templates work in director. See Understanding Heat Templates and Environment Files for reference.
