==============================================
Running FESOM's CI Jobs without GitHub Actions
==============================================

To run and fine-tune the FESOM CI jobs, you can use docker/singularity to launch the same
container that the jobs run in.

Example on Albedo
-----------------

.. code-block::

  $ module load apptainer
  Module for apptainer version 1.1.7 loaded
  $ git clone https://github.com/FESOM/fesom2.git

This gets you into the container! Now, you can follow the rest of the steps here: https://github.com/FESOM/FESOM2_Docker/blob/master/fesom2_test/Readme.md

From inside the container
-------------------------

.. code-block::

  $ cd /fesom/fesom2
  $ bash -l configure.sh ubuntu  # Compile the model (ubuntu settings used since the container is ubuntu based)

Prepare the run with whatever test you want to run:

.. code-block::

  $ mkrun pi test_pi -m docker

Now, run the test simulation:

.. code-block::

  $ cd work_pi
  $ ./job_docker_new
