First, thank you for contributing to testcontainers-rs.
Most likely, your contribution is about adding support for a new docker image. Docker images are contained within the images folder. Each file represents a docker image. The files follow the name of the image on DockerHub. Please follow this convention while developing new images.
Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.
While developing, please make sure that your code is formatted using dprint fmt.
You can install dprint in various ways: https://dprint.dev/install/
Strive for creating atomic commits. That is, commits should capture a single feature, including its tests. Ideally, each commits passes all CI checks (builds, tests, formatting, linter, ...).
When in doubt, squashing everything into a single but larger commit is preferable over commits that don't compile or are otherwise incomplete.
For writing good commit messages, you may find this guide helpful.
To ensure every commit is properly formatted, you can opt into pre-defined git hooks:
git config core.hookspath .githooks
