Cluster Setup

This guide provides instructions to set up a Kubernetes cluster required for running the Umbrella Chart.

System Requirements

CPU (Cores) Memory (GB)
4 6

The above specifications are the minimum requirements for a local development setup. Adjust resources based on your workload for larger or production environments.

Supported Platforms

1. Linux & Mac

Note As already mentioned, this is the recommendation, since these two variants are the most tested ones.

Start a Minikube cluster with the following command:

minikube start --cpus=4 --memory=6gb

2. Windows

For DNS resolution to work correctly on Windows, you have two options:

Option 1: Use the Hyper-V Driver

Start Minikube with administrator privileges using the --driver=hyperv flag:

minikube start --cpus=4 --memory=6gb --driver=hyperv

Option 2: Use Docker Desktop Kubernetes

Alternatively, you can use the native Kubernetes cluster provided by Docker Desktop:

  1. Enable Kubernetes in Docker Desktop:

    • Navigate to Settings > Kubernetes and enable the Kubernetes option.

  2. Install an NGINX Ingress Controller:

    helm upgrade --install ingress-nginx ingress-nginx --repo https://kubernetes.github.io/ingress-nginx --namespace ingress-nginx --create-namespace

  3. Use 127.0.0.1 as the Cluster IP and manually configure ingress.

⚠️ The rest of the tutorial assumes a minikube cluster, however.

Verifying the Cluster

After starting Minikube or Docker Desktop Kubernetes, verify the cluster setup:

  • Check that your cluster is running:

    kubectl cluster-info

  • Open the Minikube dashboard to monitor resources:

    minikube dashboard

Recommendations

Use tools like the Minikube dashboard (or Open Lens) to visualize your cluster and deployed components.

For networking setup, proceed to the Network Setup Guide.
