Inputs

Name	Required	Description	Type	Default
command	No	`maturin` command to run	string	`build`
args	No	Arguments to pass to `maturin` subcommand	string
maturin-version	No	The version of `maturin` to use. Must match a tagged release	string	`latest`
manylinux	No	Control the manylinux platform tag on linux, ignored on other platforms, use `auto` to build for lowest compatible	string	Defaults to `auto` for the `publish` command
target	No	The `--target` option for Cargo	string
container	No	manylinux docker container image name	string	Default depends on `target` and `manylinux` options, Set to `off` to disable manylinux docker build and build on the host instead.

You can override it by supplying the container input. Note that if use official manylinux docker images for platforms other than x86_64 and i686, you will need to setup QEMU before using this action, for example

- name: Setup QEMU
  uses: docker/setup-qemu-action@v1
- uses: PyO3/maturin-action@v1
  with:
    command: build
    args: --release

Note that the actions/setup-python action won't affect manylinux build since it's containerized, so if you want to build for certain Python version for Linux, use -i pythonX.Y in the args option in PyO3/maturin-action instead, for example

- uses: PyO3/maturin-action@v1
  with:
    args: --release -i python3.10
