Use Cookiecutter to quickly generate a new HyP3 Plugin.

To create a new plugin, you'll first need to run the cookicutter. From a terminal on your local development machine, navigate to where you'd like to create the local copy of the plugin's repository. Then run cookiecutter and follow the prompts:

python3 -m pip install cookiecutter
cookiecutter https://github.com/ASFHyP3/hyp3-cookiecutter.git

Now, you should have a hyp3-<process> directory which contains a minimal HyP3 plugin.

Next, we'll need to create a new repository on GitHub for your plugin. Make sure to create your repository in the same user/organization account you set in the <GITHUB_USERNAME> field of the cookiecutter.

Your repository name should be the same as the directory name for the plugin you created on your local develop machine. (e.g., hyp3-<PROCESS_TYPE>). For the description section, you can copy in the short description you created in the cookiecutter step. You can find this in your newly-generated, README.md file, or in your command line history. Next, set the repository to "Public", and do not click the "Initialize repository with a README" box (or add a .gitignore or add a license).

We use a conda/mamba environments to manage our dependencies; you can get Mambaforge (recommended) here:

https://github.com/conda-forge/miniforge#mambaforge

And you can get Miniconda here:

https://docs.conda.io/en/latest/miniconda.html

Once conda is installed, from the repository root, you can create and activate a development environment with all the necessary dependencies

cd hyp3-<process>
conda env create -f environment.yml
conda activate hyp3-<process>

You should now have a development environment with all the required packages for a generic HyP3 plugin. Later, as dependencies change, you can edit the environment.yml file and then update your environment with

conda env update -f environment.yml

We want to push the local copy we just created to our GitHub repository:

# From hyp3-<process>
git init .
git remote add origin https://github.com/<GITHUB_USERNAME>/hyp3-<PROCESS_TYPE>.git
git add .
git commit -m "Minimal HyP3 plugin created with the hyp3 plugin cookiecutter"
git branch -M main
git push -u origin main

We also want to create a zeroth production version from this initial commit so that the plugin's auto-versioning will work correctly.

git tag -a v0.0.0 -m "Marking zeroth release for auto-versioning and CI/CD Tooling"
git push --tags

Then add a development branch:

git checkout -b develop
git push -u origin develop

Once the zeroth release is pushed to GitHub, we need to configure the GitHub repository settings. The settings detailed here are not required, but we STRONGLY recommend them as they make it much easier for others to collaborate on your project, and for you to control how the collaboration occurs.

Go to your repository in GitHub and on the right, click "Settings", then:

1. In main page:
   • In the "Pull Requests" section
     • un-click "Allow squash merging"
     • Make sure "Automatically delete head branches" is clicked
     • See Pull Request section screenshot for configuration image
2. In "Branches":
   • make sure the default branch is "develop"
   • Add a "Branch protection rule" for:
     • main:
       • set "Branch name pattern" to "main"
       • click "Require pull request review before merging"
       • click "Dismiss stale pull request approvals when new commits are pushed"
       • click "Require status checks to pass before merging"
       • click "Do not allow bypassing of the above settings"
       • click "Restrict who can push to matching branches"
       • Create
       • See Main branch rules section screenshot for configuration image
     • develop:
       • set "Branch name pattern" to "develop"
       • click "Require pull request review before merging"
       • click "Require status checks to pass before merging"
       • click "Do not allow bypassing of the above settings"
       • Create
       • See Develop branch rules section screenshot for configuration image

For both the main and develop you can restrict who can push to the branch. In the same page where you set the above options, you can also click "Restrict who can push to matching branches", then search and add the desired people/organizations who are allowed to push. If you set this, make sure you include the owner of your repository in this list - other your GitHub Actions won't work!

For more information on how to contribute to repositories set up in this manner, check out GitHub's GitHub flow article

Some of the GitHub actions (release.yml and tag-version.yml) need extra permissions to work properly. These actions will attempt to use the GITHUB_PAK secret to assume a user profile with the needed permissions, so we'll need to create the permissions/secret.

1. In your user/organization settings:
   • Click on Developer Settings
   • Click on Personal access tokens
   • Click Tokens (classic)
   • Click Generate new token
   • Click Generate new token (classic)
   • In the note section give the token a name (e.g., GITHUB_PAK)
   • Check the boxes for:
     • repo
     • workflow
     • write:packages
     • See GITHUB_PAK permissions section screenshot for configuration image
   • Click Generate token
   • Copy your access token and save it for the next step
2. In your HyP3 plugin repository:
   • Click on Settings
   • Click on Secrets and variables
   • Click on Actions
   • Click on New repository Secret
   • Name your secret GITHUB_PAK
   • Paste in the access token you save from the last step
   • Click Add secret

This access token will regularly expire unless you set them to last forever (which we don't recommend) so make sure to keep the token current and the secret up to date!

Now you're all setup! You should be able to navigate to your repository "Actions", restart the failed Workflows on develop, and watch it create minimal HyP3 plugin container for your process.

Once the Actions have successfully run, a containerized version of your plugin will be available in the GitHub Container Registry (GHCR). You can find this plugin in the "Packages" section of your GitHub user/organization account. You can also pull it to your local machine for use using the command:

docker pull ghcr.io/<GH_ACCOUNT_NAME>/<GH_REPOSITORY_NAME>

GHCR containers are private by default. You'll need to manually change the visibility of your container to "Public" so that HyP3 can access it. See this GitHub Documentation for a step-by-step guide.
