=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
 
==Get an Individual Attribute Only==
