3 years ago Some examples of what these KWs are useful for.
Doing:
List Cluster Custom Objects k8s.cni.cncf.io v1 network-attachment-definitions
gives you an object that lists all network attachment definitions and is basically the same as:
curl -s http://localhost:8080/apis/k8s.cni.cncf.io/v1/network-attachment-definitions | jq

}Now if you know a name of network configuration there should be (or get the name from the above) you can query configuration of a specific network.

Fixes #53
This branch is on top of pull-request #47 if that's merged first this hopefully applies nicely after it. Don't know how flexible github is with this workflow. We'll see.
