Configuring Jenkins

While our goal is to configure production-ready Jenkins out of the box, there are some steps that need to be configured manually after you deploy your instance.

Keeping Jenkins up to date

Jenkins is pulled from the Jenkins repos for your distro (currently we only support Ubuntu). As long as your OS is configured to update automatically, you'll always pull in the latest version of Jenkins. For Debian/Ubuntu, install unattended-upgrades.

Development

Requirements:

• Docker v18
• pipenv

Install the dependencies.

$ pipenv install --dev

Run the tests.

$ pipenv run test

Accessing Jenkins

Once converged in molecule, you can access the Jenkins image locally. First, get the IP address of the docker container.

$ docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' jenkins-bionic

Then open your web browser to that IP on port 8080.
