I assume you mean the helper for COPY/ADD is pulled from the registry. That is not the case since Buildkit v0.5 / Docker v19.03 . If you have images you use locally, network connectivity is not required, otherwise, BuildKit will verify that the mutable tags have not changed in the registry (eg. it doesn't use the string "latest" to verify the validity of cache).
- pulse7 7y agoThe message without internet connection is: ERROR resolve image config for docker.io/docker/dockerfile:1.0-experimental (the most current version of Docker Desktop for Windows - 2.0.0.3 with Docker Engine 18.09.2)
- AnthonBerg 7y agoWhich is indeed not Docker 19.03 :)
- toniti 7y agoAs I mentioned you need to have the images you use available locally (eg. `docker images | grep docker/dockerfile`). In your Dockerfile you explicitly say that you want to use docker/dockerfile:1.0-experimental from the hub as a build frontend. If there is no such name/tag locally it needs to check the state in the registry as `1.0-experimental` tag is updated on new releases.
