How to push tagged Docker releases to Google Artifact Registry with a GitHub Action

Here's how I configured a GitHub Action so that a new version issued by GitHub's release interface will build a Dockerfile, tag it with the version number and upload it to Google Artifact Registry.

Before you attempt the steps below, you need the following:

  • A GitHub repository that contains a working Dockerfile
  • The Google Cloud SDK tool gcloud installed and authenticated

ETag middleware for use with Axum. It'd be nice to write a proper implementation as a Tower service.

req: Request<B>,

let path = req.uri().path().to_owned();

let (mut parts, mut body) = res.into_parts();
