INSTALLATION

Clone the corn repo and install with pip:

git clone https://gitlab.com/saltstack/pop/corn.git
pip install -e corn

EXECUTION

After installation the corn command should now be available

Note* Until a vertically app-merged project is also installed it will have no output

TESTING

install requirements-test.txt with pip and run pytest:

pip install -r corn/requirements-test.txt
pytest corn/tests

VERTICAL APP-MERGING

Instructions for extending corn for a kernel-specific project

Install pop:

pip install --upgrade pop

Create a new directory for the project:

mkdir pop_{kernel}
cd pop_{kernel}

Use pop-seed to generate the structure of a project that extends corn and idem:

pop-seed -t v pop_{kernel} -d corn exec states

• “-t v” specifies that this is a vertically app-merged project

• “-d corn exec states” says that we want to implement the dynamic names of “corn”, “exec”, and “states”

Add “corn” to the requirements.txt:

echo "corn @ git+https://gitlab.com/saltstack/pop/corn.git" >> requirements.txt

Note* url based reqs aren’t supported on older versions of setuptools To pip install your vertically app-merged project install corn manually:

pip install -e git+https://gitlab.com/saltstack/pop/corn.git#egg=chunkies

And that’s it! Go to town making corn, execution modules, and state modules specific to your kernel. Follow the conventions you see in corn.
