============
Ceph Upgrade
============
This guide documents steps showing Ceph version upgrade. The main goal of this
document is to demostrate Ceph chart update without downtime for OSH components.
Test Scenario:
==============
Upgrade Ceph component version from ``12.2.4`` to ``12.2.5`` without downtime
to OSH components.
Setup:
======
- 3 Node (VM based) env.
- Followed OSH multinode guide steps to setup nodes and install k8 cluster
- Followed OSH multinode guide steps upto Ceph install
Plan:
=====
1) Install Ceph charts (12.2.4) by updating Docker images in overrides.
2) Install OSH components as per OSH multinode guide.
3) Upgrade Ceph charts to version 12.2.5 by updating docker images in overrides.
Docker Images:
==============
1) Ceph Luminous point release images for Ceph components
.. code-block:: console
Ceph 12.2.4: ceph/daemon:master-0351083-luminous-ubuntu-16.04-x86_64
Ceph 12.2.5: ceph/daemon:master-a8d20ed-luminous-ubuntu-16.04-x86_64
2) Ceph RBD provisioner docker images.
.. code-block:: console
quay.io/external_storage/rbd-provisioner:v0.1.0
quay.io/external_storage/rbd-provisioner:v0.1.1
3) Ceph Cephfs provisioner docker images.
.. code-block:: console
quay.io/external_storage/cephfs-provisioner:v0.1.1
quay.io/external_storage/cephfs-provisioner:v0.1.2
Steps:
======
.. note::
Follow all steps from OSH multinode guide with below changes.
1) Install Ceph charts (version 12.2.4)
Update ceph install script ``./tools/deployment/multinode/030-ceph.sh``
to add ``images:`` section in overrides as shown below.
.. note::
OSD count is set to 3 based on env setup.
.. note::
Following is a partial part from script to show changes.

.. note::
``ceph_bootstrap``, ``ceph-config_helper`` and ``ceph_rbs_pool`` images
are used for jobs. ``ceph_mon_check`` has one script that is stable so no
need to upgrade.
2) Deploy and Validate Ceph
.. code-block:: console

9) Upgrade Ceph charts to update version
Use Ceph override file ``ceph.yaml`` that was generated previously and update
images section as below
``cp /tmp/ceph.yaml ceph-update.yaml``
Update, image section in new overrides ``ceph-update.yaml`` as shown below
.. code-block:: yaml
