Downloading and running Jenkins in Docker Jenkins in Docker
-
Open up a terminal window.
-
Create a bridge network in Docker using the following docker network create command:
docker network create jenkins
- In order to execute Docker commands inside Jenkins nodes, download and run the docker:dind Docker image using 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
- Customise official Jenkins Docker image, by executing below two steps.
a. Create Dockerfile with the following content:
FROM jenkins/jenkins:2.375.2
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"
b. Build a new docker image from this Dockerfile and assign the image a meaningful name, e.g. "myjenkins-blueocean:2.375.2-1":
docker build -t myjenkins-blueocean:2.375.2-1 .
- Run your own myjenkins-blueocean:2.375.2-1 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:2.375.2-1

docker exec -it myjenkins-blueocean:2.375.2-1 bash
docker logs myjenkins-blueocean:2.375.2-1
When you first access a new Jenkins instance, you are asked to unlock it using an automatically-generated password.
- Browse to http://localhost:8080 (or whichever port you configured for Jenkins when installing it) and wait until the Unlock Jenkins page appears.
- From the Jenkins console log output, copy the automatically-generated alphanumeric password (between the 2 sets of asterisks).
