The uv.lock file in your charm’s root directory specifies the exact versions of your charm’s dependencies and your development dependencies.

This file is required if your charm uses the uv plugin. It’s also required if you use tox with tox-uv. For more information, see tox.ini file.

When a charm is initialized with the Kubernetes or machine profile, Charmcraft creates this file.

If you change your charm’s dependencies, use uv lock to update this file. Alternatively, you can update this file by using uv add and uv remove to manage dependencies in the pyproject.toml file.

You shouldn’t manually edit this file.

For the 12-factor app profiles, this file isn’t necessary. Dependencies are specified in the requirements.txt file instead of pyproject.toml.
