Deploying multuple Ceph clusters

This guide shows how to setup multiple Ceph clusters. One Ceph cluster will be used for k8s RBD storage and while other Ceph cluster will be for tenant facing storage backend for Cinder and Glance.

Ceph Clusters:

Ceph for RBD:

This Ceph cluster will be used for k8s RBD storage (pvc). This can be used by entire Kubernetes cluster.

  • k8s namespace: ceph
  • mon endpoint port: 6789
  • mgr endpoint port: 7000
  • metric port: 9283
  • storage classes: general (rbd based for pvc)
  • no ceph-mds and ceph-rgw

Ceph for Tenant:

This Ceph cluster will be used by Cinder and Glance as storage backend.

  • k8s namespace: tenant-ceph
  • mon endpoint port: 6790
  • mgr endpoint port: 7001
  • metric port: 9284
  • no storage classes
  • no ceph-mds

Env Setup:

6 VM based hosts (node1, node2, node3, node4, node5, node6)

k8s node labels:

Ceph for RBD related labels:

Labels assigned to nodes: node1, node2, node3:

openstack-control-plane=enabled, ceph-mon=enabled, ceph-mgr=enabled, ceph-rgw=enabled, ceph-mds=enabled, ceph-osd=enabled

Ceph for Tenant related labels:

Labels assigned to nodes: node1, node2, node3:

tenant-ceph-control-plane=enabled, ceph-mon-tenant=enabled, ceph-mgr-tenant=enabled, ceph-rgw-tenant=enabled

Labels assigned to nodes: node4, node5, node6:

openstack-data-plane=enabled, openstack-compute-node=enabled, ceph-osd-tenant=enabled, openstack-data-plane=enabled

k8s node list with labels After applying above labels, node labels should look like following.

ubuntu@node1:~$ kubectl get nodes --show-labels=true

Test Steps:

1) Prepare scripts:

OpenStack-Helm multinode guide includes scripts which are used to specify overrides and deploy charts.

Duplicate scripts as shows below for later use.

cd tools/deployment/multinode/
cp 030-ceph.sh 030-tenant-ceph.sh
cp 040-ceph-ns-activate.sh 040-tenant-ceph-ns-activate.sh
cp 090-ceph-radosgateway.sh 090-tenant-ceph-radosgateway.sh

2) Deploy ingress chart:

Script to update and execute: 020-ingress.sh

Update script to include namespace tenant-ceph as shown below.

for NAMESPACE in openstack ceph tenant-ceph; do

Execute script.

3) Deploy Ceph for RBD:

Script to update and execute: 030-ceph.sh

Update script with following overrides. Note: The original RBD provisioner is now deprecated. The CSI RBD provisioner is selected here. If you prefer the original non-CSI RBD provisioner, then set rbd_provisioner to true instead.

deployment:
  storage_secrets: true
  ceph: true
  rbd_provisioner: false
  csi_rbd_provisioner: true
  cephfs_provisioner: false
  client_secrets: false
endpoints:
  ceph_mon:
    namespace: ceph
    port:
      mon:
        default: 6789
  ceph_mgr:
    namespace: ceph
    port:
      mgr:
        default: 7000
      metrics:
        default: 9283
manifests:
  deployment_mds: false
bootstrap:
  enabled: true
conf:
  pool:
    target:
      osd: 3
storageclass:
  rbd:
    ceph_configmap_name: ceph-etc
  cephfs:
    provision_storage_class: false
ceph_mgr_modules_config:
  prometheus:
    server_port: 9283
monitoring:
  prometheus:
    enabled: true
    ceph_mgr:
      port: 9283

Note

cephfs_provisioner: false and provision_storage_class: false are set to false to disable cephfs. deployment_mds: false is set to disable ceph-mds

Execute script.

4) Deploy MariaDB, RabbitMQ, Memcached and Keystone:

Use default overrides and execute following scripts as per OSH guide steps:

  • 040-ceph-ns-activate.sh
  • 050-mariadb.sh
  • 060-rabbitmq.sh
  • 070-memcached.sh
  • 080-keystone.sh

Result from Steps 2, 3, 4:

5) Deploy Ceph for Tenant:

Script to update and execute: 030-tenant-ceph.sh

Make following changes to script: 1 Replace occurrence of ceph-fs-uuid.txt with tenant-ceph-fs-uuid.txt

2 Replace occurrence of ceph.yaml with tenant-ceph.yaml

3 For tenant Ceph, no need to deploy ceph-provisioners. Update script to for CHART in ceph-mon ceph-osd ceph-client; do

Update script's override section with following:

Note

- Port numbers for Ceph_Mon and Ceph_Mgr are different from default. - We are disabling rbd and cephfs provisioners. - Labels for mon, osd, rgw, mgr and job have been updated for tenant Ceph. - Under storageclass section, values for following have been updated: ceph_configmap_name, admin_secret_name, admin_secret_namespace, user_secret_name - Under storage: mon directory have been updated.

For Tenant Ceph, we will not be provisioning storage classes therefor, update script to not install ceph-provisioners chart as following.

for CHART in ceph-mon ceph-osd ceph-client; do

Execute script.

6) Enable Openstack namespace to use Tenant Ceph:

Script to update and execute: 040-tenant-ceph-ns-activate.sh
