Seems like I can’t pull a docker image manifest, hosted at github packages, from at least one Google Cloud location.
root@gate1:~# docker pull docker.pkg.github.com/fleetsix/main-api/main-api:1.0.0
WARNING: Failed to pull manifest by the resolved digest. This registry does not
appear to conform to the distribution registry specification; falling back to
pull by tag. This fallback is DEPRECATED, and will be removed in a future
release. Please contact admins of https://docker.pkg.github.com.
this is europe-west1b (Belgium)
While from another location it pulls ok (europe west3c (Frankfurt)).
