Simple way to build jenkins step by step!

Suggest you to install Jenkins with docker.

1. Install Docker first
   (This step is assumed and will be skipped.)

2. Create a bridge network in Docker using the following docker network create command:

   docker network create jenkins
   

3. To allow Jenkins to execute Docker commands, download and run the docker:dind Docker image with the following docker run command:

   docker run --name jenkins-docker --rm --detach \
   --privileged --network jenkins --network-alias docker \
   --env DOCKER_TLS_CERTDIR=/certs \
   --volume jenkins-docker-certs:/certs/client \
   --volume jenkins-data:/var/jenkins_home \
   --publish 2376:2376 \
   docker:dind --storage-driver overlay2
   

4. Create the Dockerfile with the following content (feel free to customize it as needed):

   FROM jenkins/jenkins:2.462.3-jdk17
   USER root
   RUN apt-get update && apt-get install -y lsb-release
   RUN curl -fsSLo /usr/share/keyrings/docker-archive-keyring.asc \
   https://download.docker.com/linux/debian/gpg
   RUN echo "deb [arch=$(dpkg --print-architecture) \
   signed-by=/usr/share/keyrings/docker-archive-keyring.asc] \
   https://download.docker.com/linux/debian \
   $(lsb_release -cs) stable" > /etc/apt/sources.list.d/docker.list
   RUN apt-get update && apt-get install -y docker-ce-cli
   USER jenkins
   RUN jenkins-plugin-cli --plugins "blueocean docker-workflow"
   

5. Build a new Docker image from this Dockerfile and name it myjenkins-blueocean:2.462.3-1 using the following command:

   docker build -t myjenkins-blueocean:2.462.3-1 .
   

6. Run your own myjenkins-blueocean:2.462.3-1 image as a container in Docker using the following docker run command:

   docker run --name jenkins-blueocean --restart=on-failure --detach \
   --network jenkins --env DOCKER_HOST=tcp://docker:2376 \
   --env DOCKER_CERT_PATH=/certs/client --env DOCKER_TLS_VERIFY=1 \
   --publish 8080:8080 --publish 50000:50000 \
   --volume jenkins-data:/var/jenkins_home \
   --volume jenkins-docker-certs:/certs/client:ro \
   myjenkins-blueocean:2.462.3-1
   

7. By default,the Jenkins url is http://127.0.0.1:8080/, once you enter the website,you need the password for unlocking Jenkins,paste the command in terminal and copy the the website:

    docker exec jenkins-blueocean cat /var/jenkins_home/secrets/initialAdminPassword
   

8. Select "Install suggested plugins"

9. browse the website and register a account for yourself

10. Start to practice Jenkins!!
