Private repository: declare the address in the pyproject.toml or not?

[andrearota]

Hello, I am new to Poetry. I am running on a corporate network and I am using a Nexus server instance to serve a PyPi group repository, i.e. a PyPi compatible repository that mix internal private packages and public content from PyPi.org (cached).

I don't want Poetry to connect to PyPi.org, as it is not reachable from the internal network, so I set the group repository as default and primary source.

Should I declare the full repository address in the pyproject.toml file, as it follows?

[[tool.poetry.source]]
name = "pypi-group-registry"
url = "https://my-group-registry.example.com:8443/repository/pypi-group/simple"
default = true
secondary = false

Or is there a way to avoid pinning the address in the code and let the user to define the real address of the repository?

From my point of view, I don't like the idea of having addresses hardwired in my descriptors.
