Install Kestra on Kubernetes

How to Install Kestra on Kubernetes with Helm

This guide will walk you through the process of installing Kestra 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 Kestra
• Kubernetes Ingress controller - For accessing the installation on a url

Step 1: Add the Helm chart repository

First, add the repository containing the Kestra helm chart:

helm repo add kestra https://helm.kestra.io
helm repo update
helm search repo kestra

Step 2: Create a namespace (optional)

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

kubectl create namespace kestra

Step 3: Install Kestra using Helm

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

helm install kestra kestra/kestra --namespace kestra --create-namespace

Step 4: Verify the installation

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

kubectl get pods --namespace kestra
kubectl get all --namespace kestra

Step 5: Customize the Kestra installation (optional)

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

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

Step 6: Access Kestra

Accessing Kestra 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.
