Install authentik on Kubernetes

How to Install authentik on Kubernetes with Helm

This guide will walk you through the process of installing authentik using Helm, the Kubernetes package manager, ensuring a smooth and efficient setup.

Prerequisites

Before we begin, ensure you have the following tools installed and configured:

• Kubernetes - Installed locally or in a public cloud provider
• kubectl - Configured to communicate with your Kubernetes cluster
• Helm - For managing Kubernetes applications like authentik
• Kubernetes Ingress controller - For accessing the installation on a url

Step 1: Add the Helm chart repository

First, add the repository containing the authentik helm chart:

helm repo add authentik https://charts.goauthentik.io
helm repo update
helm search repo authentik

Step 2: Create a namespace (optional)

Isolating applications within Kubernetes namespaces is a good practice. To deploy authentik in its own namespace:

kubectl create namespace authentik

Step 3: Install authentik using Helm

Now, you'll install authentik. The helm chart name is "authentik":

helm install authentik authentik/authentik --namespace authentik --create-namespace

Step 4: Verify the installation

After installation, verify that your authentik deployment is running smoothly:

kubectl get pods --namespace authentik
kubectl get all --namespace authentik

Step 5: Customize the authentik installation (optional)

This process may require customizing your deployment through a customized values.yaml file, which specifies configuration options.

helm install authentik authentik/authentik --values values.yaml --namespace authentik

Step 6: Access authentik

Accessing authentik will depend on your chosen service configuration (LoadBalancer, NodePort, or Ingress). For Ingress access, ensure an Ingress controller is operational in your cluster.

Follow the instructions in the helm install notes, the output of Step 3.
