Running A Local Jenkins

It's often helpful to run Jenkins in a container locally to test various scenarios with JTE during development.

just run

With the default settings, this will expose jenkins on http://localhost:8080

Change the container name

just --set container someName run

Change the port forwarding target

just --set port 9000 run

Pass arbitrary flags to the container

Parameters passed to just run are sent as flags to the docker run command.

just run -e SOMEVAR="some var"

Mounting local libraries for testing

Local directories can be configured as Git SCM Library Sources even if they don't have a remote repository.

For example, if ~/local-libraries is a directory containing a local git repository then to mount it to the container you would run:

just run -v ~/local-libraries:/local-libraries

You could then configure a Library Source using the file protocol to specify the repository location at file:///local-libraries

Tip

When using this technique, changes to the libraries must be committed to be found. In a separate terminal, run:

just watch ~/local-libraries

to automatically commit changes to the libraries.
