I want to have full control of what I do with my single node cluster (savings...lol), but somehow I can't do this even if I delete the deployment it respawns ..
As mentioned in another answer, you cannot delete them directly via the Kubernetes API; however, you can delete them indirectly via the Google Container Engine API.
To remove the dashboard, run gcloud container clusters update $CLUSTER_NAME --update-addons=KubernetesDashboard=DISABLED.
To disable heapster you need to disable monitoring using gcloud container clusters update $CLUSTER_NAME --monitoring-service=none (it may actually require disabling another add-on too, I can't recall at the moment).
See https://cloud.google.com/sdk/gcloud/reference/container/clusters/update for the commands referenced above.
Heapster is configured as a cluster addon. The addon manager is going to reconcile it to it's preconfigured state if you change or delete it.
You are stuck with it.
Even if you delete heapster pod; it restart automatically. I can made it with scaling it down to zero as shown below
kubectl scale --replicas=0 deployment/heapster-v1.6.0-beta.1 --namespace=kube-systemAnd you can find the exact name of the heapster pod within result of the command below
kubectl get deployments --namespace=kube-systemBy the way you can find more options to reduce resource usage here: https://cloud.google.com/kubernetes-engine/docs/how-to/small-cluster-tuning
