To Redistribute
Get the Manifest for an Existing Object
The manifest can be used to recreate the object:
kubectl get pod pod-name --export -o yaml
Note that --export is deprecated and will be removed in the future so find an equivalent.
Kill Immediately
kubectl delete -n my-ns pod my-pod --force --grace-period=0
Logging
"Tail" logging:
kubectl -n my-namespace logs -f my-pod
Logging that survives pod restart:
while ! kubectl -n my-namespace logs -f my-pod; do sleep 1; done
Port Fowarding
while ! kubectl -n my-namespace port-forward service/my-service 8787:8787; do sleep 1; done
