docker build error

[YouSeeYouOneDayDayDe]

When I run the command "docker build . -t local-package-feeds", an error occured as follows:

DEPRECATED: The legacy builder is deprecated and will be removed in a future release.
BuildKit is currently disabled; enable it by removing the DOCKER_BUILDKIT=0
environment-variable.

It seems that the domain can not be connected, how to solve this problem?

Hi, I tried to reproduce the this issue and it appears to have gone away.

I suspect the gcr.io connection issue was transient.

Please try again, and let me know if the issue still persists.

I tried again, but the problem still persists. I tried to access the website “https://gcr.io/v2/” in browser, and the raw data returned by server is as follows.

{"errors":[{"code":"UNAUTHORIZED","message":"Unauthorized access."}]}

The request headers are as follows.

Is there anything wrong with my network connection or project configuration? I haven't made any changes to any files in this project.

1. Does docker pull gcr.io/distroless/base:nonroot generate the same response?
2. Have you tried running docker build . -t local-package-feeds on a different host?
3. Have you tried restarting your machine and trying again?
4. If you have any proxies configured, try and connect directly.

As far as I can tell this is not an issue with the package-feeds project. A search of the web shows this as an occasional problem for other docker users.
