Jenkins in Cloud: GCP Setup

1. Introduction

In this lesson, we will explore how to set up Jenkins in Google Cloud Platform (GCP). Jenkins is an open-source automation server that enables developers to build, test, and deploy applications. Running Jenkins in the cloud allows for scalable and flexible CI/CD pipelines.

2. Prerequisites

3. GCP Setup

The first step is to set up the necessary resources in GCP:

1. Log in to your GCP account.
2. Create a new project.
3. Enable the Compute Engine API.
4. Create a VM instance:
Note: Choose an OS image, preferably Ubuntu for Jenkins.
5. Configure firewall rules to allow HTTP and HTTPS traffic.

gcloud compute instances create jenkins-instance \
    --zone=us-central1-a \
    --machine-type=e2-medium \
    --image-family=ubuntu-2204-lts \
    --image-project=ubuntu-os-cloud

4. Jenkins Installation

SSH into your VM instance and install Jenkins:

sudo apt update
sudo apt install openjdk-11-jdk
wget -q -O - https://pkg.jenkins.io/debian/jenkins.io.key | sudo apt-key add -
echo "deb http://pkg.jenkins.io/debian-stable binary/" | sudo tee /etc/apt/sources.list.d/jenkins.list
sudo apt update
sudo apt install jenkins

Start Jenkins:

sudo systemctl start jenkins
sudo systemctl enable jenkins

Access Jenkins at http://:8080.

5. Configuration

To complete the setup, configure Jenkins as follows:

1. Obtain the Jenkins unlock key:

sudo cat /var/lib/jenkins/secrets/initialAdminPassword

2. Use the unlock key to set up Jenkins through the web interface.
3. Install suggested plugins.
4. Create an admin user.
