# Docker Jenkins
-This is a jenkins repo for building some CI pipelines.
-
+Run Jenkins in a docker container and give it socket access to build/run other
+docker containers. This was an experiement for a presentation I did on docker.
## Lessons Learned
-- `/var/jenkins_home` probably needs 777 permissions `docker.sock` probably
-- needs 777 permissions since user/groups get confused SSH creds can be
-- generated by jenkins user. Git commands require those creds
- added into `credentials` and if you have scripts that use ssh then you will
- want to add those ssh creds to `publish over ssh` so that pipelines can ssh
- into other machines

- Keep the filepath of `jenkins_home` the same on host and in container so if
- you need volume mounts inside the container, they will be translated
- correctly onto the host machine
-- Running docker with `userns` will make things more complicated with
- user/group translations
