How to point Azure Function publish to custom python registry?

Question

How do I point the Azure Function publish function of Azure Function Core Tools to a custom registry such as an enterprise ArtiFactory instance?

Example:

• When running func azure functionapp publish <FunctionAppName>, how do I get requirements.txt to install from a registry I choose rather than pypi?
• Very similar to changing npm's default registry.

Answer 1

The command runs pip install, so any environment variables pip looks for will work.

• If you need all your modules from the custom registry, set PIP_INDEX_URL
• If you need just some of your modules, then set PIP_EXTRA_INDEX_URL

Note that the func azure functionapp publish <FunctionAppName> command performs a Remote Build by default. So, you would have to set the required environment variable as an app setting.

Optionally, you could perform a local build by running func azure functionapp publish <FunctionAppName> --build local.

Also, you could also set the same configuration in pip's config file for local builds.
