Helm

Helm is package manager for Kubernetes.

Helm makes it easy to install charts (an application) on kubernetes clusters. Just like npm or apt make it easy to install NodeJS modules and Debian packages, helm makes it easy to deploy a full-fledged application with all of its dependencies on kubernetes.

Install Tiller

The helm tiller is the server-side component of Helm. It’s used to cordinate with the kubernetes cluster in order to deploy resources (E.g. Services, Deployments, StatefulSets, etc.)

To install the tiller, just run helm init from the Geodesic shell after assumming-role and running kops export kubecfg.

assume-role
kops export kubecfg
helm init

(Note, in older versions of kops you will need to pass the cluster name, so run kops export kubecfg $KOPS_CLUSTER_NAME)

Delete All Releases in Namespace

To delete all helm releases in NAMESPACE, run the following command:

helm list --namespace $NAMESPACE --short | xargs helm delete --purge

Note

Deleting releases will not delete the namespace itself. This is because there may be other artifacts. For a more detailed discussion on the pros & cons of this, check out the GitHub issue tracking this topic.

Then after running this command, to delete the namespace, run:

kubectl delete namespace $NAMESPACE
