Opening a pull request

(for contributors)

To add software to EESSI, you should go through the semi-automatic software installation procedure by:

  • 1) Making a pull request to the software-layer repository to (add or) update an easystack file 📚 that is used by EasyBuild to install software;
  • 2) Instructing the bot 🤖 to build the software on all supported CPU microarchitectures;
  • 3) Instructing the bot 🤖 to deploy the built software for ingestion into the EESSI repository;
  • 4) Merging the pull request once CI indicates that the software has been ingested. ✅

Warning

Make sure you are also aware of our contribution policy when adding software to EESSI.

Preparation

Before you can make a pull request to the software-layer, you should fork the repository in your GitHub account.

For the remainder of these instructions, we assume that your GitHub account is @koala 🐨.

Note

Don't forget to replace koala 🐨 with the name of your GitHub account in the commands below!

1) Clone the EESSI/software-layer repository:

mkdir EESSI
cd EESSI
git clone https://github.com/EESSI/software-layer
cd software-layer

2) Add your fork 🐨 as a remote

git remote add koala git@github.com:koala/software-layer.git

3) Check out the branch that corresponds to the version of EESSI repository you want to add software to, for example 2023.06:

git checkout 2023.06

Note

The commands above only need to be run once, to prepare your setup for making pull requests.

Creating a pull request

1) Make sure that your 2023.06 branch in the checkout of the EESSI/software-layer repository is up-to-date

cd EESSI/software-layer
git checkout 2023.06
git pull origin 2023.06

2) Create a new branch (use a sensible name, not example_branch as below), and check it out

git checkout -b example_branch

3) Determine the correct easystack file to change, and add one or more lines to it that specify which easyconfigs should be installed

echo '  - example-1.2.3-GCC-10.3.0.eb' >> eessi-2023.06-eb-4.7.2-2021a.yml

4) Stage and commit the changes into your your branch with a sensible message

git add eessi-2023.06-eb-4.7.2-2021a.yml
git commit -m "adding example 1.2.3 with GCC/10.3.0 to EESSI pilot 2023.06"

5) Push your branch to your fork 🐨 of the software-layer repository

git push koala example_branch

6) Go to the GitHub web interface to open your pull request, or use the helpful link that should show up in the output of the git push command.

Make sure you target the correct branch: the one that corresponds to the version of EESSI you want to add software to (like 2023.06).

If all goes well, one or more bots 🤖 should almost instantly create a comment in your pull request with an overview of how it is configured - you will need this information when providing build instructions.
