AI Gamer Project - Part 2 - Setting Up

This is going to be night one of the project.

I'm hoping I can get the setup done in one go!. I'll leave my commands here in this blog incase you want to try to follow along. Bear in mind I'm going to be learning this as I go as well!

Step 1: Prerequisites

Ensure you have the following installed:

• WSL 2 with a Linux distribution (Ubuntu is recommended)
• Docker Desktop
• kubectl (Kubernetes CLI)
• Helm (for package management in Kubernetes)
• Minikube (or K3s, but we'll start with Minikube)

I had WSL running on my system already so if you're jumping in you'll need to see how to do that yourself.

Docker

Update your package list and install dependencies

sudo apt update && sudo apt install ca-certificates curl gnupg

Add Docker’s official GPG key

sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo tee /etc/apt/keyrings/docker.asc > /dev/null
sudo chmod a+r /etc/apt/keyrings/docker.asc

Add the Docker repository

echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Install Docker

sudo apt update && sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

Enable Docker to run without sudo (optional but recommended)

sudo usermod -aG docker $USER
newgrp docker

Verify Docker is installed correctly

docker --version
docker run hello-world

Restart WSL

wsl --shutdown

then reopen WSL

minikube

install Minikube

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube

Start Minikube using Docker as the driver

minikube start --driver=docker

Verify that the cluster is running

kubectl get nodes -A

Download and Install Helm

# Add the Helm repository
curl -fsSL https://baltocdn.com/helm/signing.asc | sudo tee /usr/share/keyrings/helm.asc > /dev/null

# Add the Helm APT Repo
echo "deb [signed-by=/usr/share/keyrings/helm.asc] https://baltocdn.com/helm/stable/debian/ all main" | sudo tee /etc/apt/sources.list.d/helm-stable-debian.list

# Update package lists and install Helm and Verify Install
sudo apt update && sudo apt install helm
helm version

Deploy Prometheus and Grafana

Add the helm repo and update

helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo add grafana https://grafana.github.io/helm-charts
helm repo update

Install prometheus and Grafana in Kubernetes

helm install prometheus prometheus-community/kube-prometheus-stack --namespace monitoring --create-namespace
helm install grafana grafana/grafana --namespace monitoring --set persistence.enabled=true --set persistence.size=10Gi

After install Grafana you'll get a prompt with how to get your admin password and how to access the application. Please note this command down so you can get this password when you need it.

Get Grafana admin password

kubectl get secret --namespace monitoring grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo

Verify a PVC was created for grafana so your dashboards persist

kubectl get pvc -n monitoring

Expose Grafana so you can acces it from your browser

kubectl port-forward svc/grafana 3000:80 -n monitoring

http://localhost:3000

Grafana is up and running

Check in

How's your set up looking so far?

So at this point my kubernetes cluster looks like this and hopefully yours does too! If you had any hang ups up to this point leave them in the comments below and I'll try to help!
