Upgrade Kommander in a Pre-provisioned Environment

Prerequisites

• Ensure you meet all prerequisites stated in the Kommander upgrade section.

• Ensure you have set up a minimum of 4 x 40 GB of raw (unformatted disk) storage for each of the worker nodes of your cluster. We recommend setting up 1 volume per node, or multiple volumes per node only if node pool is less than 4.

Modify Rook Ceph’s Deployment

1. Clone the kommander-applications repo to your local machine where you are running the upgrade:

   CODE

   git clone --depth 1 --branch v2.4.2 https://github.com/mesosphere/kommander-applications.git

2. Prepare rook-ceph for the upgrade by editing the storage specifications of the rook-ceph-cluster:

   CODE

   cd kommander-applications/services/rook-ceph-cluster/1.10.8/defaults/
   vi cm.yaml

3. Adapt the cephClusterSpec.storage in cm.yaml to include the following values:

   CODE

       storageClassDeviceSets: []
       useAllDevices: true
       useAllNodes: true

4. Delete the following value in the same file:

   CODE

       onlyApplyOSDPlacement

Upgrade the Kommander component of DKP

1. Ensure you are targeting the correct DKP version:

   CODE

   dkp version

   The output should show the current binary version, in this case, DKP 2.4.0.

2. Execute the upgrade by specifying the repository you cloned and updated in the previous section:

   CODE

   dkp upgrade kommander --kommander-applications-repository ./kommander-applications --platform-apps-timeout
