When a cluster which has been provisioned by TMC, and therefore managed by TMC, has an available upgrade, you will see an “i” icon next to the version on the clusters UI view, hovering over this will tell you there is an upgrade ready.

TMC - Clusters - Upgrade Available

Click the cluster name to take you into the cluster object to see the full details,

  1. click the actions button
  2. and select upgrade.

TMC - Cluster - Actions - Upgrade

The Upgrade Cluster dialogue will appear. Select the version you want to upgrade to and click upgrade.

TMC - Cluster - Upgrade Cluster - Select Version

On both the Cluster list and Cluster Detailed view, the status will change to upgrading.

TMC - Cluster Upgrading 2TMC - Cluster Upgrading

Once the upgrade has completed, the cluster will change back to ready and show the updated version.

Wrap-up and Resources

In this quick blog post, we used Tanzu Mission Control to upgrade a provisioned Tanzu Kubernetes Grid cluster which was running in AWS. All the steps provided in this blog post can be replicated using the TMC CLI as well.

As a reminder, to take real advantage of TMC I recommend you read the follow posts:

We are going to use the cluster I created in my last blog post.

Below are my EC2 instances that make up my TMC provisioned cluster, here I have filtered my view using the field “tmc.cloud.vmware.com/cluster” + cluster name.

Deleting a Provisioned cluster in the TMC UI

In the TMC UI, going to the clusters view, you can click the three dots next to the cluster you want to remove and select delete.

Tanzu Mission Control - Clusters - Delete cluster

Alternatively, within the cluster object view, click actions then delete.

Tanzu Mission Control - Cluster Object - Delete cluster

Both options will bring up the below confirmation dialog box.

You select one of the following options:

  • Delete and remove agent (recommended)
    • Remove from TMC and delete agent extensions
  • Manually delete agent extensions
    • A secondary option whereby a manual removal is needed if a cluster delete fails

Enter the name of the cluster you want to delete, to confirm the cluster deletion.
