When you attempt to deploy a new Tanzu Kubernetes Grid (TKG) Management Cluster to a vSphere 7.0 environment, you may have noticed a message stating that you may want to enable the Tanzu Kubernetes Grid Service (TKGs) alternatively.
Running TKG and TKGs on vSphere 7.0 is fully supported and depending on your use case, you may want to enable one or the other. In either situation, you are always prompted with a question which you must answer before you can continue. Awhile back I was looking into whether there were any CLI options to override this behavior and simply answer in advanced but did not see anything in the CLI help menu.
I recently ran into this again and while asking around, I came to learn that were are indeed two (hidden) options that can be used to override and disable these prompts, which can be useful for unattended automation purposes. Although these options are hidden from the CLI help options, I am not exactly sure why this is the case, they are officially documented in the TKG documentation.
- --deploy-tkg-on-vSphere7 can be used to confirm that you wish to deploy a TKG Management Cluster on vSphere 7
- --enable-tkgs-on-vSphere7 can be used to confirm that you will be using the TKGs as your Management Cluster in vSphere 7
With this information, we can now pass in the --deploy-tkg-on-vSphere7 option as shown in the example below and you will no longer be prompted:
tkg init -i vsphere -p dev --name tkg-mgmt --vsphere-controlplane-endpoint-ip 192.168.30.127 --deploy-tkg-on-vSphere7
A fascinating discussion is worth comment. I believe that you should write more about this topic, it might not be a taboo subject but generally people don't talk about these issues. To the next! Best wishes!!
