Meltano

does meltano support installing extractors/loaders from alternative package repositories?

Currently just whatever `pip install` supports, so that's PyPI and (public/private) Git repos

We have an issue to support Docker images: <https://gitlab.com/meltano/meltano/-/issues/2205>

Or are you thinking alternatives to PyPi, like a private package index?

yeah, we use jfrog artifactory to host private python packages

typically we just install by specifying a separate `--index-url` via pip

You can use pip's environment variables. Basically set `PIP_INDEX_URL` or `PIP_EXTRA_INDEX_URL` in your environment. I've installed taps from s3pypi packages doing something like <https://gitlab.com/meltano/meltano/-/issues/2689#note_542505658|this> before. There's also a <https://www.meltano.com/docs/plugin-management.html#installing-plugins-from-a-custom-python-package-index-pypi|section> in the plugin management docs.

Oh right forgot about those! Thanks <@U06BX9QQ4A3>
