================================
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.

.. code-block:: console

  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.

.. code-block:: console

  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.

.. code-block:: yaml

  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.

.. code-block:: yaml

  deployment:
    storage_secrets: true
    ceph: true
    rbd_provisioner: true
    cephfs_provisioner: false
    client_secrets: false
    rgw_keystone_user_and_endpoints: 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``
