Helm Cabin

Helm Cabin is a web UI that visualizes Helm releases in a Kubernetes cluster.

I wasn't able to find a simple web UI that visualizes the data managed by Tiller without hiding information behind additional abstractions. I decided to scratch my own itch and started Helm Cabin as part of Hacktoberfest 2019.


  • Supports Helm 2 & 3
  • List all releases with any status (deleted, superseded, deployed, etc.)
  • View revisions, rendered manifest, chart templates, chart values and chart files for any release

Install Helm Cabin with the provided chart.

helm repo add helm-cabin
helm repo update
helm upgrade --install --set-string helmVersion=3 helm-cabin helm-cabin/helm-cabin

Helm Cabin doesn't handle TLS itself. Please use a reverse proxy, e. g. Traefik, for TLS termination.

Build from source

Helm Cabin uses Magefile as task run. Check out the mage targets in Magefile.go, the scripts section in web/package.json and build/Dockerfile to see how the project is built.


If you work in Helm 2 mode:

# Port-forward to tiller if you work in Helm 2 mode
kubectl port-forward svc/tiller-deploy -n kube-system 44134:44134
# Start the frontend through vue-cli-service. 
# The vue dev server proxies requests starting with /api to localhost:8080
# The frontend will be served on localhost:8081 by default.
npm --prefix web run serve
# Start the backend on localhost:8080 (assumes tiller is reachable at localhost:44134 in Helm 2 mode
# or a valid kube context is set in Helm 3 mode)
mage RunServer

Project architecture

The project layout is based on golang-standards/project-layout.


The backend periodically retrieves all releases including deleted releases and superseded revisions
from Tiller (Helm 2) or Kubernetes secrets (Helm 3). The result is cached in memory.

Helm Cabin tries to connect with Tiller via tiller-deploy.kube-system.svc.cluster.local by default. The tiller host can be overriden with the tillerAddress CLI flag. Use port forwarding for local development.

If you work in Helm 3 mode, Helm Cabin uses the current context to connect to Kubernetes.


The frontend source is located in the web directory and uses VueJS. Take a look at the frontend README for usage instructions.
