instructions

build

docker build -t jenkins-docker .

run as deamon with web server on port 8080

docker run -it -d -p 8080:8080 -p 50000:50000 -v jenkins_home:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock --restart unless-stopped jenkins-docker

to get admin password

(wait a minute for the daemon / web server to finish starting up)

docker exec -it $(docker ps -qf "ancestor=jenkins-docker") cat /var/jenkins_home/secrets/initialAdminPassword

logging in

setting up the pipeline

• Install the recommended plugins
• Select 'Continue as admin' then 'Save and Finish' and 'Restart' then refresh the browser and re-enter the admin credentials.
• Select 'New item', enter a name for the project, select 'Feestyle project' and click 'OK'
• Select source code management: git and enter the HTTPS URL of your fork of the sample-flask-app repository
• Under the heading 'Build' select 'Add build step' > 'Execute shell' In the 'Command' box enter: docker-compose down; docker-compose up -d; sleep 10; docker-compose logs
• Save
• Build Now
• On the command line on your host machine, enter docker ps and you will see the app running.
• In the browser, browse to 'localhost:8000' to see your app.

This will execute the flask app on the jenkins server.

to get a terminal on the jenkins container

docker exec -it $(docker ps -qf "ancestor=jenkins-docker") bash 

You can find the working directory at /var/jenkins_home/workspace/.

remove jenkins-docker image (to clean up when we're done)

docker kill $(docker ps -qf "ancestor=jenkins-docker") 2> /dev/null ; docker image rm jenkins-docker --force; docker image prune --force
