How to request support for your GKSv3 cluster

You can find the list of the Support here

In case of requesting changes in the machineDeployment, please specify the machineDeployment where the changes should be applied. A format like md-name-az-md or cluster-name-az-mdis required so that we refer to the correct machineDeployment.

We will handle the requested changes or reach out for more details if needed before applying them to your cluster.
