Multi-arch build using buildx gets stuck at pushing the image to Docker Hub

Docker Desktop
1

Hi,
I am trying to build a multi-arch docker image using buildx. I use the following command.

docker buildx build --platform linux/amd64,linux/arm64 -t adityasamantlearnings/customers:v1 --push .

The build proceeds to the step of pushing the image to DockerHub’s remote repository.

At this stage my build hangs showing the logs below, probably due to an authentication issue.

 => => pushing layers                                                                                                                                      601.2s
 => [auth] adityasamantlearnings/customers:pull,push token for registry-1.docker.io                                                                          0.0s

My repository exists. I am able to successfully push regular images using docker image push with no issues.

Just the push with docker buildx fails.

I have already authenticated my remote repository using docker login

Any idea what could be the issue?

P.S. A complete fresh install of Docker Desktop for Mac doesn’t help as well.

OS Version: Macos Sonoma 14.2.1
Docker Desktop for Mac: 24.0.7

It is working for me now, although I am not sure of the root cause.

I did the following:

  1. Uninstall and reinstall of the Docker Desktop → this did not help.
  2. Created a new auth token for Docker and used docker login with the token instead of password → this did not help initially as well.

After some time, without any further change, the images started being pushed.

So I am not clear on what fixed it, but I don’t have the energy to investigate further on the root cause :wink:

I’m experiencing this too :frowning:
any ideas?

Docker Hub has now introduced explicit HTTP 429 errors to at least indicate the root cause: Austere rate limits.

Even with a paid team subscription, multiplatform uploads are rate limited to the point of malfunctioning.

Tag aliases exacerbte this problem:

Update:

After careful observation, noticed that I had restated one of my tag (aliases) twice in the buildx tag aliasing command. Deduplicated tag names.

The –platform flag appears to be redundant in buildx tag aliasing commands. Removed that as well.

Made minor alterations to Docker source contents, which then alters the image checksums.

At long last, the rate limit error appears to have disappeared. Unknown exactly why. Suspect that the low level HTTP security apparatus may be poorly tuned for multiplatform operations, where repeated HTTP requests of the same contents are the norm rather than the exception. Expect on the order of 12^3 similar HTTP requests, when an account pushes or pulls objects involving multiplatform images.
