Helmless Kubernetes operator

The Helmless Operator is a Kubernetes operator designed to deploy any Helm chart using values from any .yaml based file URL. It allows users to create a custom resource that specifies the chart repository, chart name, chart version, namespace, and the URL containing the values file.

Prerequisites

• Kubernetes cluster
• kubectl installed and configured to interact with the cluster
• Helm v3.x installed

Installation

1. Clone the Helmless Operator repository:

git clone https://github.com/ccokee/helmless-operator.git
cd helmless-operator

2. Deploy the Helmless Operator CRD:

kubectl apply -f config/crd/bases/helmless.redrvum.cloud_helmlesses.yaml

3. Install the operator's deployment and related resources:

kubectl apply -f helmless-operator.yaml

Usage

1. Create a helmless-deployer.yaml file containing the HelmLess custom resource:

apiVersion: cache.redrvm.cloud/v1alpha1
kind: HelmLess
metadata:
  labels:
    app.kubernetes.io/name: helmless
    app.kubernetes.io/instance: helmless-0
    app.kubernetes.io/part-of: helmless
    app.kubernetes.io/managed-by: kustomize
    app.kubernetes.io/created-by: helmless-operator
  name: helmless-deployer
spec:
  chartRepo: <your-chart-repo>
  chartName: <your-chart-name>
  chartVersion: "<your-chart-version>"
  chartReleaseName: "<your-release-name>"
  namespace: default
  valuesUrl: <.yaml-url-with-values>

Replace <your-chart-repo>, <your-chart-name>, <your-chart-version>, <your-release-name> and <.yaml-url-with-values> with the corresponding details of the Helm chart you want to deploy.

2. Apply the HelmLess custom resource:

kubectl apply -f helmless-deployer.yaml

The Helmless Operator will now deploy the specified Helm chart using the values provided in the public Gist.

Example

To deploy any Helm chart, follow these steps:

1. Create a public Gist containing your desired values for the chart. The Gist URL will look like https://gist.github.com/username/gist_id.

2. Update the publicGist field in the helmless-deployer.yaml file with your Gist URL. Also, update the chartRepo, chartName, and chartVersion fields with the details of the Helm chart you want to deploy.

3. Apply the HelmLess custom resource:

kubectl apply -f helmless-deployer.yaml

The Helmless Operator will deploy the specified Helm chart using the values from your public Gist.

Uninstall

To remove the Helmless Operator and its custom resources:

1. Delete the HelmLess custom resource:

kubectl delete -f helmless-deployer.yaml

2. Uninstall the operator's deployment and related resources:

kubectl delete -f helmless-operator.yaml

3. Delete the Helmless CRD:

kubectl delete -f config/crd/bases/helmless.redrvum.cloud_helmlesses.yaml

This will clean up all resources related to the Helmless Operator.
