| # Build and publish a Docker image. | |
| # | |
| # Assumed to run as a subworkflow of .github/workflows/release.yml; specifically, as a local | |
| # artifacts job within `cargo-dist`. | |
| # | |
| # TODO(charlie): Ideally, the publish step would happen as a publish job within `cargo-dist`, but | |
| # sharing the built image as an artifact between jobs is challenging. | |
