🚀 Jenkins CI/CD Pipeline Setup (WSL + Windows Environment)

This guide walks you through setting up a CI/CD pipeline using Jenkins, Docker, Minikube, kubectl, and Argo CD in a Windows + WSL (Ubuntu) hybrid environment.

---

🛠️ Prerequisites

Ensure the following are installed on your system:

• Windows 10/11
• Windows Subsystem for Linux (WSL)
• Ubuntu (via WSL)
• Docker Desktop for Windows
• Minikube installed on Windows
• kubectl installed on Windows
• All tools should be accessible from your localhost

---

📦 Step 1: Install Git

Run inside Ubuntu WSL:

sudo apt update
sudo apt install git -y

---

🐳 Step 2: Install Docker (on Ubuntu WSL)

Although Docker Desktop runs on Windows, Jenkins runs in WSL, so Docker CLI must also be available in WSL:

Install Docker inside WSL: 👉 https://docs.docker.com/engine/install/ubuntu/

After installation, allow docker to access sudo:

sudo groupadd docker
sudo usermod -aG docker $USER

Ensure Docker works in WSL:

docker ps

---

☕ Step 3: Install Java (for Jenkins)

Run in Ubuntu WSL:

sudo apt install openjdk-21-jre-headless -y

---

⚙️ Step 4: Install Jenkins (in Ubuntu WSL)

Follow the Jenkins installation guide: 👉 https://www.jenkins.io/doc/book/installing/linux/#debianubuntu

After installation:

sudo systemctl start jenkins
sudo systemctl enable jenkins

After installation, allow Jenkins to access Docker:

sudo usermod -aG docker jenkins
sudo systemctl restart jenkins

Access Jenkins via:

http://localhost:8080

---

🔌 Step 5: Jenkins Plugin Setup

After accessing Jenkins UI, install the following plugins:

• Git Plugin
• Pipeline Plugin
• Docker Pipeline Plugin

---

🔐 Step 6: Set Up Jenkins Credentials

In Jenkins Dashboard:

1. Navigate to: Manage Jenkins > Credentials

2. Add:

   • DockerHub credentials (username/password)
   • GitHub credentials (username/password or SSH key)

Example:

ID	Type	Purpose
dockerhub-creds	Username/Password	Push Docker images
git-https-creds	Username/Password	GitOps repo automation

---

☸️ Step 7: Install kubectl (on Windows)

Follow guide: 👉 https://kubernetes.io/docs/tasks/tools/install-kubectl-linux/

⚠️ Make sure kubectl is accessible globally (e.g., added to PATH).

---

🌱 Step 8: Install Minikube (on Windows)

Minikube runs on Windows (not WSL). Download and install: 👉 https://minikube.sigs.k8s.io/docs/start/

Start minikube:

minikube start --driver=docker

🚀 Step 9: Install Argo CD (Optional for GitOps)

Follow Argo CD setup: 👉 https://argo-cd.readthedocs.io/en/stable/getting_started/

After installation, retrieve the admin password:

kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d

Login via browser:

kubectl port-forward svc/argocd-server -n argocd 9090:443

http://localhost:9090

---

✅ Final Notes

• Jenkins runs inside WSL (Ubuntu)
• Docker, Minikube, and Kubernetes tools run on Windows
• All components communicate via localhost

You are now ready to run full CI/CD pipelines with Docker builds, GitOps deployments, and Kubernetes!
