docker image for latest tag is not multiarch

[frederikhs]

I expect the latest tag to be available for both arm64 and amd64, but it seems that it is not.

The nightly image is published for both arm64 and amd64

$ docker manifest inspect getsentry/relay:nightly

   "mediaType": "application/vnd.oci.image.index.v1+json",
   "manifests": [

      },

      },

            "os": "unknown"
         }
      }

Mh, that's because we don't publish a latest tag (-> it is outdated), I need to find when we stopped publishing latest.

[Dav1dde]

Okay, seems like latest is pushed with the self hosted release, which does not push a multiarch image.

[Dav1dde]

Craft doesn't seem to handle multi arch images ... Opened an issue there.

[Dav1dde]

Craft PR which should make this work: getsentry/craft#556

[Dav1dde]

Craft 2.0.0 released with support for copying multi arch images, next release should have the multi arch image pushed 🙏 .
