This ansible role is used to install jenkins and any plugins you might want.
By default it installs the following packages that jenkins will need.
git
curl
build-essentials
gradle
These will typically be needed to handle all tasks to manage jenkins and run containerized builds
And the following plugins
git
gradle
as they are needed to handle gradle based jenkins configuration (configuraiton as jenkins jobs)
Lastly it also installs docker inside the container, which we will use talk to a mounted docker.sock from the host machine. This allows the jenkins container to handle builds using docker without running docker in docker.
Since this is intended to run in a conatiner in the foreground, we do not enable the jenkins service to automatically start. We do however start the jenkins server during build to allow for plugin installations.
