ChartMuseum

public

An open source helm chart repository. It is handy for quickly setting up a helm repository via docker.

Start up ChartMuseum

First, start up a container, and supply a local folder as the volume for the charts (-v). Also we can protect it with password and username (e.g. if there is the goal to experiment with credentials).

docker run --rm -it \
  -p 8080:8080 \
  -e DEBUG=1 \
  -e STORAGE=local \
  -e STORAGE_LOCAL_ROOTDIR=/charts \
  -e BASIC_AUTH_USER=chartuser \
  -e BASIC_AUTH_PASS=mypass \
  -v $(pwd)/charts:/charts \
  ghcr.io/helm/chartmuseum:v0.16.2

Create a Helm Chart

Now create a helm chart locally.

helm create busybox

Edit the deployment so that it does not contain the container ports and also add the container command line arguments:

containers:  
  - name: {{ .Chart.Name }}  
    securityContext:  
      {{- toYaml .Values.securityContext | nindent 12 }}  
    image: "{{ .Values.image.repository }}:{{ .Values.image.tag | default .Chart.AppVersion }}"  
    imagePullPolicy: {{ .Values.image.pullPolicy }}  
    command:  
      - sleep  
      - infinity  
    resources:  
      {{- toYaml .Values.resources | nindent 12 }}

Modify the values as follows:

image:  
  repository: busybox  
  # This sets the pull policy for images.  
  pullPolicy: IfNotPresent  
  # Overrides the image tag whose default is the chart appVersion.  
  tag: "latest"

Package and push the helm chart

Create a helm package

helm package .

and push it to the repo

curl -u chartuser --data-binary "@busybox-0.1.0.tgz"

Now see that it is listed with:

curl -u chartuser  -X GET http://localhost:8080/api/charts

Add the repo to the machine

helm repo add my-helm-repo --username chartuser
