Intro

Assume we have some Helm chart we want to deploy, but we don't want to install Tiller on our Kubernetes cluster. This doc will cover how to deploy a helm chart without installing Tiller on the cluster, but will not go into the motivations or tradeoffs of doing so.

Prereqs

1. Helm installed locally
2. Helm initialized (helm init --client-only)
3. kubectl working for your cluster

Steps

1. Add the repo to Helm
   $ helm repo add $repoName $repoUrl
$ helm repo update
2. Download and extract the chart
   $ helm fetch $repoName/$chartName --untar
3. Apply the chart to your cluster using helm template
$ helm template $chartName --name $releaseName --namespace $targetNamespace | kubectl -n $targetNamespace apply -f -
   1. Use --set on the helm command to set value overrides.
   2. Remove the pipe to kubectl and add --notes -x templates/NOTES.txt to view the post-deploy notes.
