Alps Uenv Recipes

This repository manages the recipes for uenv on CSCS' Alps clusters, and the definition of the CI/CD pipeline that deploys them.

See the documentation for an overview of the uenv, and a packaging guide.

First steps

The project is structured as follows:

.
├── ci                      # CI/CD pipeline configuration file
├── docs                    # Documentation files, see `mkdocs.yml`
├── recipes                 # uenv configuration files based on spack
├── workflow                # pipeline scripts and utils
├── README.md
├── config.yaml             # define available target systems for uenv build
└── mkdocs.yml 

Creating a new uenv can be accomplished by adding a new recipe to the recipes folder as laid out under recipe writing best practices and updating the top-level config.yaml file with the uenv information and matching target system. The uenv itself is created via the script found in the workflow folder:

.
├── workflow                    # scripts and utils
│   ├── pipeline                # CI/CD utils
│   ├── util                    # auxiliary scripts for uenv build and test
│   ├── configure-pipeline      
│   ├── stage-build             # script executed during pipeline build stage
│   └── stage-test              # script executed during pipeline test stage
└── ...

If testing locally, first invoke configure-pipeline to the pipeline.yml configuration file for the given target system. This file will then be consumed during the execution of the stage-build and stage-test scripts, which can be triggered locally for testing purposes but will in general be executed directly by the CI/CD runner.
