This post is about how kolla-ansible performs openstack docking with ceph. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

1. Prerequisites:

Deployed openstack and ceph clusters

Storage pool created

Prepare ceph.conf,(Glance, Cinder, Nova)keyring: as shown below

2. Set up ceph client authentication, and execute the following command on one of the ceph nodes:

ceph auth get-or-create client.cinder mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=volumes, allow rwx pool=vms, allow rwx pool=images'

ceph auth get-or-create client.glance mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=images'

ceph auth get-or-create client.cinder-backup mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=backups'

3. Connect to the glance service and perform the following operations:

ceph auth get-or-create client.glance

The requested URL/etc/kolla/config/glance/ceph.client.glance.keyring was not found on this server.

To connect to the finder service, perform the following operations:

ceph auth get-or-create client.cinder

Save the output to/etc/kolla/config/cinder-backup/ceph.client.cinder.keyring

/etc/kolla/config/cinder/cinder-volume/ceph.client.cinder.keyring

ceph auth get-or-create client.cinder-backup

Save the output to/etc/kolla/config/finder/cinder-backup/ceph.client.cinder-backup.keyring

ceph auth get-or-create client.nova

Save the output to/etc/kolla/config/nova/ceph.client.cinder.keyring

4. Place the ceph.conf configuration file in/etc/kolla/config/cinder/, glare/, nova/,

Edit/etc/kolla/config/glance/glance-api.conf and add the following

[DEFAULT]

show_image_direct_url = True

[glance_store]

stores = rbd

default_store = rbd

rbd_store_pool = images

rbd_store_user = glance

rbd_store_ceph_conf = /etc/ceph/ceph.conf

Edit/etc/kolla/config/cinder/cinder-volume.conf and add the following

[DEFAULT]

enabled_backends=rbd-1

[rbd-1]

rbd_ceph_conf=/etc/ceph/ceph.conf

rbd_user=cinder

backend_host=rbd:volumes

rbd_pool=volumes

volume_backend_name=rbd-1

volume_driver=cinder.volume.drivers.rbd.RBDDriver

rbd_secret_uuid = {{ cinder_rbd_secret_uuid }}

Note: cinder_rbd_secret_uuid must be found in the file/etc/kolla/passwords.yml

7. Edit/etc/kolla/config/cinder/cinder-backup.conf and add the following

[DEFAULT]

backup_ceph_conf=/etc/ceph/ceph.conf

backup_ceph_user=cinder

backup_ceph_chunk_size = 134217728

backup_ceph_pool=backups

backup_driver = cinder.backup.drivers.ceph

backup_ceph_stripe_unit = 0

backup_ceph_stripe_count = 0

restore_discard_excess_bytes = true

Edit/etc/kolla/config/nova/nova-compute.conf and add the following

[libvirt]

virt_type=qemu

images_rbd_pool=vms

images_type=rbd

images_rbd_ceph_conf=/etc/ceph/ceph.conf

rbd_user=nova

Note: rbd_user may vary depending on your environment.

9. Execute kolla-ansible -i multinode reconfigure

10. Restart the container
