Ceph Support

[Sergio Aguilar]

Are there any plans to support Ceph?

I saw some pages mentioning it but not for openstack-ansible.
https://community.rackspace.com/products/f/45/t/1658

Is there a way we can just specify the ceph settings for glance, cinder and nova? I mean I'm not trying to deploy ceph just connect it to an existing one.

Thank you,

Hello @Sergio Aguilar,

The ceph work is presently being worked on by Serge and can be found in the following commits:

Master:
https://review.openstack.org/#/c/181957/

Juno:
https://review.openstack.org/#/c/181022/

These commits will enable ceph support within the OSAD environment and should suit your imediate needs. As for general ceph support deployed by and managed by this project thats up for debate. If you have some cycles and would like to review the work in progress we'd greatly appreciate it. Additionally we have weekly meeting and an active IRC channel that you can find more about here: https://wiki.openstack.org/wiki/Meetings/openstack-ansible

I hope this help.

Hello @Kevin Carter,

Thanks so much for the link and the information. This is precisely what I was looking for.

I will definitely review it and give it a shot.

Saludos,

Sergio

Hi,

Maybe it could be easier to re-use this https://github.com/ceph/ceph-ansible ?

Hi Alexandre,

For now, the ceph support is meant to configure openstack/osad to *use* a ceph cluster, whch is what I'm working on.
I suppose on the longer run, there might be support to also install and configure a ceph cluster, which is where the ceph-ansible will be a good contenderto look at, but that has not been discussed yet.

    Add Ceph/RBD support to playbooks

    Currently the playbooks do not allow Ceph to be configured as a backend
    for Cinder, Glance or Nova. This commit adds a new role called
    ceph_client to do the required configuration of the hosts and updates
    the service roles to include the required configuration file changes.
    This commit requires that a Ceph cluster already exists and does not
    make any changes to that cluster.

    ceph_client role, run on the OpenStack service hosts
      - configures the Ceph apt repo
      - installs any required Ceph dependencies
      - copies the ceph.conf file and appropriate keyring file to /etc/ceph
      - creates the necessary libvirt secrets

    os_glance role
    glance-api.conf will set the following variables for Ceph:
      - [DEFAULT]/show_image_direct_url
      - [glance_store]/stores
      - [glance_store]/rbd_store_pool
      - [glance_store]/rbd_store_user
      - [glance_store]/rbd_store_ceph_conf
      - [glance_store]/rbd_store_chunk_size

    os_nova role
    nova.conf will set the following variables for Ceph:
      - [libvirt]/rbd_user
      - [libvirt]/rbd_secret_uuid
      - [libvirt]/images_type
      - [libvirt]/images_rbd_pool
      - [libvirt]/images_rbd_ceph_conf
      - [libvirt]/inject_password
      - [libvirt]/inject_key
      - [libvirt]/inject_partition
      - [libvirt]/live_migration_flag

    os_cinder is not updated because ceph is defined as a backend and that
    is generated from a dictionary of the config, for an example backend
    config, see etc/openstack_deploy/openstack_user_config.yml.example

    pw-token-gen.py is updated so that variables ending in uuid are assigned
    a UUID.
