Two nice Pivotal Container Service (PKS) CLI commands I use very often

Having always created multiple PKS clusters at times I forget the configuration of my K8S clusters and this command comes in very handy

First lets list those clusters we have created with PKS

papicella@papicella:~$ pks clusters

Name    Plan Name  UUID                                  Status     Action
lemons  small      5c19c39e-88ae-4e06-a1cf-050b517f1b9c  succeeded  CREATE
banana  small      7c3ab1b3-a25c-498e-8179-9a14336004ff  succeeded  CREATE

Now lets see how many master nodes and how many worker nodes actually exist in my cluster using "pks cluster {name} --json"

papicella@papicella:~$ pks cluster banana --json

   "name": "banana",
   "plan_name": "small",
   "last_action": "CREATE",
   "last_action_state": "succeeded",
   "last_action_description": "Instance provisioning completed",
   "uuid": "7c3ab1b3-a25c-498e-8179-9a14336004ff",
   "kubernetes_master_ips": [
   "parameters": {
      "kubernetes_master_host": "",
      "kubernetes_master_port": 8443,
      "kubernetes_worker_instances": 3

One final PKS CLI command I use often when creating my clusters is the --wait option so I know when it's done creating the cluster rather then continually checking using "pks cluster {name}"

papicella@papicella:~$ pks create-cluster cluster1 -e -p small -n 4 --wait
