Get Kinds and Versions supported by a Kubernetes Cluster

Quick way to enumerate capabilities supported by a Kubernetes cluster

Each Kubernetes version and installation supports different sets of capabilities based on what and how they were installed. To identify all these capabilities you need to execute multiple kubectl commands like kubectl api-versions and a lot more to get a usable list.

The collect capability of Move2Kube can be exploited to get this list too. To do that,

1. Install Move2Kube
2. Set the cluster in context for your kubectl
3. Run move2kube collect
4. You will find all data in a file named m2k_collect/clusters/<clusterid>.yaml

In addition to the Kinds and versions it also lists all storage classes supported by the cluster. As we enhance capabilities of Move2Kube, and as more info about the cluster is required, we will augment them to the collect capability.
