Up to this point, the project has been set up as a Docker action
referencing the Dockerfile. The downside to using the Dockerfile for the
action is that the Docker image must be built every time the action is
used.
This commit will set up the project to build the Docker image and push
it to GitHub Container Registry (GHCR). This change will speed up user
workflows every time the action is used because the workflows will
simply pull the Docker image from GHCR instead of building again.
Changes:
- Add required metadata to Dockerfile
- Build container image with GitHub Actions
- Push container image to GHCR
Docker actions support pulling in pre-built Docker images. The downside
is that there's no way to specify the correct Docker tag because the
GitHub Actions `image` and `uses:` keys don't accept any context.
For example, if a user's workflow has
`uses: pypa/gh-action-pypi-publish@release/v1.8`, then the action should
pull in a Docker image built from the `release/v1.8` branch, something
like `ghcr.io/pypa/gh-action-pypi-publish:release-v1.8` (Docker tags
can't have `/`). The workaround is to switch the top-level `action.yml`
to a composite action that then calls the Docker action, substituting
the correct image name and tag.
PR #236
This patch adds PEP 740 attestation generation to the workflow: when the Trusted Publishing flow is used, this will generate a publish attestation for each distribution being uploaded. These generated attestations are then fed into `twine`, which newly supports them via `--attestations`.

The previous release didn't take into account the action defaults so
the promised fallbacks for the old input names didn't work. This patch
corrects that mistake.
Up until now, the action input names followed the snake_case naming
pattern that is well familiar to the pythonistas. But in GitHub
actions, the de-facto standard is using kebab-case, which is what
this patch achieves.
This style helps make the keys in YAML better standardized and
distinguishable from other identifiers.
The old snake_case names remain functional for the time being and will
not be removed until at least v3 release of this action.
d7872a6165 changed the name of an input from `dist` to `packages-dir`,
but unfortunately it looks like GitHub actions expect underscores rather
than dashes, so deploys are currently broken with the following errors:
```
Run pypa/gh-action-pypi-publish@master
with:
user: __token__
password: ***
packages-dir: dist
env:
pythonLocation: /opt/hostedtoolcache/Python/3.8.0/x64
/usr/bin/docker run --name [...] -e INPUT_PACKAGES-DIR [...]
/app/twine-upload.sh: line 22: INPUT_PACKAGES_DIR: unbound variable
This patch replaces the dash with an underscore.
Resolves#20
