Custom Resource Definitions¶

Check what CRDs are¶

$ kubectl get crd

$ kubectl get crd <crd> -o yaml

Get instances of a specific crd

$ kubectl get <crd_name> -A

$ kubectl debug node/node_name --it --image bash

Or use the node-admin krew plugin. Another cool trick:

kubectl run h0nk --rm -it \
 --image alpine --privileged \
 --overrides '{"spec":{"hostPID": true}}'\
 --command nsenter – \
 --mount=/proc/1/ns/mnt
