Build image

(Optional) myjenkins-blueocean is distinguishable name, as default docker automatic create a identify name.

docker build -t myjenkins-blueocean:2.440.3-1 .

Run the Container

1. ( Optional ) Specifies the Docker container name for this instance of the Docker image.
2. Always restart the container if it stops. If it is manually stopped, it is restarted only when Docker daemon restarts or the container itself is manually restarted.
3. ( Optional ) Runs the current container in the background, known as "detached" mode, and outputs the container ID. If you do not specify this option, then the running Docker log for this container is displayed in the terminal window.
4. Connects this container to the jenkins network previously defined. The Docker daemon is now available to this Jenkins container through the hostname docker.
5. Specifies the environment variables used by docker, docker-compose, and other Docker tools to connect to the Docker daemon from the previous step.
6. Maps, or publishes, port 8080 of the current container to port 8080 on the host machine. The first number represents the port on the host, while the last represents the container’s port. For example, to access Jenkins on your host machine through port 49000, enter -p 49000:8080 for this option.
7. the TCP port for inbound Jenkins agents of your Jenkins controller to 51000, you need to re-run Jenkins via the docker run …​ command. Specify the "publish" option as follows: the first value is the port number on the machine hosting the Jenkins controller, and the last value matches the changed value on the Jenkins controller, for example,--publish 52000:51000. Inbound Jenkins agents communicate with the Jenkins controller on that port (52000 in this example). Note that WebSocket agents do not need this configuration.
8. Maps the /var/jenkins_home directory in the container to the Docker volume with the name jenkins-data. Instead of mapping the /var/jenkins_home directory to a Docker volume, you can also map this directory to one on your machine’s local file system. For example, specify the option --volume $HOME/jenkins:/var/jenkins_home to map the container’s /var/jenkins_home directory to the jenkins subdirectory within the $HOME directory on your local machine — typically /Users//jenkins or /home//jenkins. NOTE: If you change the source volume or directory for this, the volume from the docker:dind container above needs to be updated to match this.
9. Maps the /certs/client directory to the previously created jenkins-docker-certs volume. The client TLS certificates required to connect to the Docker daemon are now available in the path specified by the DOCKER_CERT_PATH environment variable.
10. The name of the Docker image, which you built in the previous step.

If you have problems copying and pasting the command snippet, use the annotation-free version below:

MacOS/Linux:

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 \
