Targeting specific namespaces with kubectl

Note for myself given kubectl does not allow multiple namespaces as per it's CLI

$ eval 'kubectl  --namespace='{cf-system,kpack,istio-system}' get pod;'

OR (get all) if you want to see all resources

$ eval 'kubectl  --namespace='{cf-system,kpack,istio-system}' get all;'

  
$ eval 'kubectl  --namespace='{cf-system,kpack,istio-system}' get pod;'
