Depending on a runtime you use to build your Function (Node.js or Python), your Git repository must contain at least a directory with these files:

• handler.js or handler.py with Function's code
• package.json or requirements.txt with Function's dependencies

The Function CR must contain spec.source.gitRepository to specify that you use a Git repository for the Function's sources.

To create a Function with the Git source, you must:

1. Create a Secret (optional, only if you must authenticate to the repository).
2. Create a Function CR with your Function definition and references to the Git repository.

NOTE: For detailed steps, see the tutorial on creating a Function from Git repository sources.

You can have various setups for your Function's Git source with different:

• Directory structures

  You can specify the location of your code dependencies with the baseDir parameter in the Function CR. For example, use "/" if you keep the source files at the root of your repository.

• Authentication methods

  You can define with the spec.source.gitRepository.auth parameter in the Function CR that you must authenticate to the repository with a password or token (basic), or an SSH key (key).

• Function's rebuild triggers

  You can use the spec.source.gitRepository.reference parameter in the Function CR to define whether the Function Controller must monitor a given branch or commit in the Git repository to rebuild the Function upon their changes.
