A detailed tutorial on how to install Jenkins on Docker for beginners

Jenkins is an open source software project. It is a continuous integration tool developed based on Java. It is used to monitor continuous repetitive work. It aims to provide an open and easy-to-use software platform to make continuous integration of software possible.

Basic working principle of Jenkins

The above is the basic working principle, just for developers to better understand the drawing (personal understanding), for details, please refer to the official document: https://www.jenkins.io/zh/

1. Jenkins installation

1. Find and download the jenkins image file

Start Docker and search for the Jenkins image file

docker search jenkins

Download the Jenkins image file

docker pull jenkins/jenkins

2. Create a Jenkins mount directory and grant permissions so that we can easily modify the configuration files in the container.

mkdir -p /data/jenkins_home/

chmod 777 /data/jenkins_home/

3. Create and start the Jenkins container

docker run -d -p 8090:8080 -p 8091:50000 -v /data/jenkins_home:/var/jenkins_home -v /etc/localtime:/etc/localtime --name jenkins jenkins/jenkins

• -d Run the image in the background
• -p 10240:8080 maps the mirror's port 8080 to the server's port 10240.
• -p 10241:50000 maps the mirrored port 50000 to the server's port 10241
• -v /data/jenkins_home:/var/jenkins_home The /var/jenkins_home directory is the container jenkins working directory. We mount a directory on the hard disk to this location to facilitate the use of the original working directory after subsequent image updates. Here we set the /data/jenkins_home directory we created above
• -v /etc/localtime:/etc/localtime tells the container to use the same time settings as the server.
• –name myjenkins gives the container an alias

4. Check whether Jenkins is started successfully. If the port number appears as shown in the figure below, it means that it is started successfully.

docker ps -l

5. View Docker container logs

docker logs jenkins

6. Configure image acceleration and enter the cd /data/jenkins_home directory

cd /data/jenkins_home

Modify the content in hudson.model.UpdateCenter.xml

vi hudson.model.UpdateCenter.xml

Before modification:

Change the URL to the official mirror of Tsinghua University: https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json

7. Visit the Jenkins page and enter your IP plus 8090

8. To obtain the administrator password, edit the initialAdminPassword file and enter the password you logged in with to start using it.

vi /data/jenkins_home/secrets/initialAdminPassword
