Logs

This is the command generated
/usr/bin/docker buildx build --tag ghcr.io/org/repo/img:latest --iidfile /tmp/docker-build-push-IWJ2p2/iidfile --file ./Dockerfile --push .
And this is the error after building the image

This is probably not a bug but just me doing something wrong, but can't figure out what part. Please any help is appreciated.

Thanks

Hi @dirodriguezm,

With GitHub Container Registry you can only have a single namespace (user or org) compared to GitHub Package Registry. So in your case I think you can't use ghcr.io/org/repo/img:latest tag. Try with ghcr.io/org/repo:latest instead.

Thanks, that was it.
