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.
Click the cluster name to take you into the cluster object to see the full details,
click the actions button
and select upgrade.
The Upgrade Cluster dialogue will appear. Select the version you want to upgrade to and click upgrade.
On both the Cluster list and Cluster Detailed view, the status will change to 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:
When the vRealize 8 products dropped, I was like a kid in a sweet shop, upgrading everything as quick as possible before my customers tried to, so I could encounter any issues first, but also the new features, so I could show them off.
During the upgrade of vROPs, I hit an issue that my Local Admin account in vROPs had expired, but I received no warning when using the vROPs 7.5 instance and logged into the interface using the Admin account.
Before I found the issue;
During the upgrade in vRSLCM, my upgrade task failed with “vROPS upgrade failure”, Error Code: LCMVROPSYSTEM25008, Upgrade.pak_pre_apply_validate_failed.
VMworld 2018, I was lucky enough to get my name down on the list to present on the vBrownbag stage, a community driven source of brilliant knowledge articles, videos, and web meetings, for the community by the community. Read more about vBrownbag here
In the below session I took on the session that had proved to be a hit at VMUGs around the UK. “Upgrading from vSphere 5.5 to 6.x”
This session focuses less on the “how to upgrade the components themselves” but more what you need to cover for planning and preparation, considerations during the upgrades, and calling out known gotchas.
Since the above video, I’ve since joined VMware, and presented the official slide deck covering this subject at the UK VMUG Usercon with Kev Johnson, Technical Marketing Engineer – vSphere Lifecycle.
