Docker in Jenkins (run on Docker)

README.md

REF: https://gist.github.com/afloesch/ea855b30cfb9f157dda8c207d40f05c0

For this gist, I'll use Jenkins custom image method to install Docker.

You could use docker-compose.yaml or use docker command to run your custom image.

Note: For M1, you could enable platform in docker-compose.yaml file.

commands.sh

docker run -d -p <PORT>:8080 -p <PORT>:50000 \
    -v /var/run/docker.sock:/var/run/docker.sock \
    --name <CONTAINER_NAME> <IMAGE_NAME>:<IMAGE_TAG>

docker-compose.yaml

version: "3.9"
services:
  jenkins-server:
    #platform: linux/amd64
    #build: .
    image: <IMAGE_NAME>:<IMAGE_TAG>
    ports:
      - "<PORT>:8080"
      - "<PORT>:50000"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - <YOUR_PATH>/jenkins_home:/var/jenkins_home
