Jenkins on Docker

README.md

Run Jenkins on Docker

(Option 1) Docker Compose way

1. You should have docker-compose installed. If you don't have it, get it from docker/compose release page.
2. Get the docker-compose.yml
3. Go to command line / terminal
4. Go to directory containing docker-compose.yml. Generally it will be Downloads directory
5. Run docker compose and dertach

   docker-compose up -d

6. Get init password by executing:

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

(Option 2) Do It Manually

1. Create Isolated Network

   docker network create jenkins

2. Create a docker certificate volume

   docker volume create jenkins-docker-certs

3. Create a jenkins data volume

   docker volume create jenkins-data

4. Run isolated docker environment on docker (remember inception)

   Linux/Mac

   docker container 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

   Windows

   docker container 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

5. Run jenkins

   Linux/Mac

   docker container run \
     --name jenkins-blueocean \
     --rm \
     --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 \
     jenkinsci/blueocean

   Windows

   docker container run ^
     --name jenkins-blueocean ^
     --rm ^
     --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 ^
     jenkinsci/blueocean

6. Browse jenkins console at http://localhost:8080

7. Get init password

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

docker-compose.yml

      - jenkins-docker-certs:/certs:ro
volumes:

networks:
  jenkins:

Doesnt work :(
