poetry-plugin-pypi-mirror

Description

poetry-plugin-pypi-mirror is a plugin for poetry, the Python packaging and dependency manager. It enables poetry to substitute connections to pypi.org with connections to a pypi.org mirror or pull-through cache without requiring project configuration changes. This is ideal for situations where an access-restricted or otherwise unsuitable-for-general-use pypi.org mirror must be used by a subset of project contributors. For example:

  • A private PyPI mirror internal to a business, required by company policy
  • A limited-access PyPI mirror in a region where pypi.org is restricted
  • A regional mirror that is more performant for a few users, and less performant for everyone else

These mirrors can be used without this plugin by adding them as project repositories. However, this requires the mirror to be included in the project's configuration, and this also results in source entries for the mirror appearing in poetry.lock. Since only a subset of project contributors can use these mirrors, that subset of users would need to replace and remove references to the mirror repository each time they want to contribute their changes back to the project. This is suboptimal.

Usage

Installation

Follow poetry's plugin installation instructions, replacing poetry-plugin with poetry-plugin-pypi-mirror.

Specifying a mirror

To specify a mirror, you can either define plugins.pypi_mirror.url in poetry's configuration, or set environment variable POETRY_PYPI_MIRROR_URL to the full URL for a PEP 503-compatible mirror. When both are set the environment variable will be used.

Poetry config example

[plugins]
[plugins.pypi_mirror]
url = "https://example.org/repository/pypi-proxy/simple/"

... in either a project's poetry.toml (for per-project configuration), or the user's config.toml.

Environment variable example

POETRY_PYPI_MIRROR_URL=https://example.org/repository/pypi-proxy/simple/ poetry add pendulum

...or...

export POETRY_PYPI_MIRROR_URL=https://example.org/repository/pypi-proxy/simple/
poetry add cleo # uses mirror specified in first line
poetry lock     # also uses mirror specified in first line

Authentication

If the mirror you're using requires authentication, you can add the credentials like you would for any other repository.

Please note that repository names are case-sensitive, so it is important that you configure the credentials for PyPI. pypi or other variations will not work.

poetry config http-basic.PyPI <username> <password/token>

Compatibility

poetry-plugin-pypi-mirror depends on poetry internals which can change between poetry releases. It's important to ensure compatibility between the poetry version in use and the plugin version in use.

Poetry version(s) Compatible plugin version(s)
>= 1.3, < 1.9 ^0.4.2
~1.2.1 < 0.3.0
