Installing with Docker in Jenkins - Try It Yourself

Installing Jenkins with Docker

📖 Scenario: You want to quickly set up Jenkins, a popular automation server, using Docker. Docker helps you run Jenkins inside a container without installing it directly on your computer.

🎯 Goal: Learn how to pull the official Jenkins Docker image, run a Jenkins container with the right settings, and verify Jenkins is running.

📋 What You'll Learn

Docker installed and running on your machine

Basic command line usage

Internet connection to download Docker images

💡 Why This Matters

🌍 Real World

Using Docker to install Jenkins lets you quickly set up a clean Jenkins environment without changing your main system. This is useful for testing or starting new projects.

💼 Career

Many DevOps roles require managing Jenkins servers. Knowing how to run Jenkins in Docker containers is a common and valuable skill.

1

Pull the official Jenkins Docker image

Open your terminal and run the command docker pull jenkins/jenkins:lts to download the latest stable Jenkins image.

Jenkins

# Run the command to pull Jenkins image
# Your code here

Need a hint?

This command downloads the Jenkins image tagged 'lts' (long-term support) from Docker Hub.

2

Create a Docker volume for Jenkins data

Run docker volume create jenkins-data to create a volume that will store Jenkins data persistently.

Jenkins

docker pull jenkins/jenkins:lts
# Create a Docker volume named jenkins-data
# Your code here

Need a hint?

This volume keeps your Jenkins data safe even if the container stops or is removed.

3

Run the Jenkins container with volume and port mapping

Run the command docker run -d -p 8080:8080 -p 50000:50000 -v jenkins-data:/var/jenkins_home --name jenkins-server jenkins/jenkins:lts to start Jenkins in a container with data persistence and port access.

Jenkins

docker pull jenkins/jenkins:lts
docker volume create jenkins-data
# Run Jenkins container with ports 8080 and 50000 mapped and volume attached
# Your code here

Need a hint?

This command runs Jenkins in the background, maps ports for web and agent communication, and uses the volume for data.

4

Check Jenkins container status

Run docker ps and then docker logs jenkins-server to see if Jenkins is running and view its startup logs.

Jenkins

docker pull jenkins/jenkins:lts
docker volume create jenkins-data
docker run -d -p 8080:8080 -p 50000:50000 -v jenkins-data:/var/jenkins_home --name jenkins-server jenkins/jenkins:lts
# Check running containers and Jenkins logs
# Your code here

Need a hint?

The docker ps command shows running containers. The logs should include a message like 'Jenkins is fully up and running'.
