Install Gatus on Kubernetes

How to Install Gatus on Kubernetes with Helm

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

Step 1: Add the Helm chart repository

First, add the repository containing the Gatus helm chart:

helm repo add twin https://twin.github.io/helm-charts
helm repo update
helm search repo gatus

Step 2: Create a namespace (optional)

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

kubectl create namespace gatus

Step 3: Install Gatus using Helm

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

helm install gatus twin/gatus --namespace gatus --create-namespace

Step 4: Verify the installation

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

kubectl get pods --namespace gatus
kubectl get all --namespace gatus

Step 5: Customize the Gatus installation (optional)

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

helm install gatus twin/gatus --values values.yaml --namespace gatus

Step 6: Access Gatus

Accessing Gatus 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.
