⁠Use Image

Prepare data volume. (set uid:gid to 1000:1000)

mkdir -p /data/jenkins/home
sudo chown -R 1000:1000 /data/jenkins/home

Create container.

docker run -d \
  --name jenkins \
  -e LANG=ko_KR.UTF-8 \
  -e TZ=Asia/Seoul \
  -v /payh/to/your/jenkins/home:/var/jenins_home \
  -p 8080:8080/tcp \
  docker.io/yidigun/jenkins:latest

Check secrets/initialAdminPassword from /var/jenkins_home (/data/jenkins/home) and proceed web configuration via http://localhost:8080⁠

⁠Docker in docker How-to

docker-ce-cli package is installed in this image. If you wish to build docker image in the container, consider set DOCKER_HOST variable.

docker run -d \
  --name jenkins \
  -e LANG=ko_KR.UTF-8 \
  -e TZ=Asia/Seoul \
  -v /payh/to/your/jenkins/home:/var/jenins_home \
  -p 8080:8080/tcp \
  --add-host=docker-host-machine:172.17.0.1 \
  -e DOCKER_HOST=ssh://username@docker-host-machine \
  docker.io/yidigun/jenkins:latest

Docker Remote Config⁠ needs to generate a "client certificate" for each client. This can annoy you somewhat.

Using SSH connection is much more simple. Entrypoint script will generate SSH private/public key pair in your $JENKINS_HOME using ssh-keygen. You can find public key from docker log messages or $JENKINS_HOME/.ssh/id_rsa.pub.

Genterated SSH Public Key is:
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAAB...

You can put this public key in authorized_keys of docker host machine.

⁠Building

⁠1. Build using created builder.

Check downloaded version and modify TAG macro.

make TAG=2.332.3

If you don't want push and just build image.

make TAG=2.332.3 PUSH=no

⁠3. Test image

Local build and test image. Specify /var/jenkins_home volume and web port using TEST_ARGS macro.

mkdir jenkins_home
make test TAG=2.332.3 TEST_ARGS="-v `pwd`/jenkins_home:/var/jenkins_home -p 8080:8080/tcp"
