Install n8n on Kubernetes

How to Install n8n on Kubernetes with Helm

This guide will walk you through the process of installing n8n 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 n8n
• Kubernetes Ingress controller - For accessing the installation on a url

Step 1: Add the Helm chart repository

First, add the repository containing the n8n helm chart:

helm repo add community-charts https://community-charts.github.io/helm-charts
helm repo update
helm search repo n8n

Step 2: Create a namespace (optional)

Isolating applications within Kubernetes namespaces is a good practice. To deploy n8n in its own namespace:

kubectl create namespace n8n

Step 3: Install n8n using Helm

Now, you'll install n8n. The helm chart name is "n8n":

helm install n8n community-charts/n8n --namespace n8n --create-namespace

Step 4: Verify the installation

After installation, verify that your n8n deployment is running smoothly:

kubectl get pods --namespace n8n
kubectl get all --namespace n8n

Step 5: Customize the n8n installation (optional)

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

helm install n8n community-charts/n8n --values values.yaml --namespace n8n

Step 6: Access n8n

Accessing n8n 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.
