Ansible role that installs a custom mount helper that mounts a CephFS using credentials given via a config drive. (In the future, types other than CephFS might be supported.)
Using this mount helper, one can simply run
mount -t configdrive <ID> /mnt -o _netdevto mount a CephFS under /mnt.
To make this work, the credentials must be passed as a block device under /dev/disk/by-id/<ID>.
That block device must contain a filesystem with the following files on the root level:
| Filename | Content |
|---|---|
type |
Must contain the string ceph. |
spec |
Mount source, e.g., mons.ceph.example.com:/volumes/csi/csi-vol-foo/bar. |
fs |
Name of the CephFS. This is passed to -o fs=. |
name |
Name of the Ceph client. This is passed to -o name=. |
secretfile.file |
Secret of the Ceph client. This file is passed to -o secretfile=. |
This role should work in pretty much any distribution that has an /sbin directory.
