Install Semaphore UI on Kubernetes

How to Install Semaphore UI on Kubernetes with Helm

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

Step 1: Add the Helm chart repository

First, add the repository containing the Semaphore UI helm chart:

helm repo add semaphoreui https://semaphoreui.github.io/charts
helm repo update
helm search repo semaphore

Step 2: Create a namespace (optional)

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

kubectl create namespace semaphore-ui

Step 3: Install Semaphore UI using Helm

Now, you'll install Semaphore UI. The helm chart name is "semaphore":

helm install semaphore-ui semaphoreui/semaphore --namespace semaphore-ui --create-namespace

Step 4: Verify the installation

After installation, verify that your Semaphore UI deployment is running smoothly:

kubectl get pods --namespace semaphore-ui
kubectl get all --namespace semaphore-ui

Step 5: Customize the Semaphore UI installation (optional)

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

helm install semaphore-ui semaphoreui/semaphore --values values.yaml --namespace semaphore-ui

Step 6: Access Semaphore UI

Accessing Semaphore UI 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.
