Push is denied in automated build hooks

I am currently using hooks in an automated build to pass parameters to the docker build command, and tag the resulting images. The feature is documented here: Advanced options for Autobuild and Autotest | Docker Docs

However, all my builds are now failing at the post_push step, where the docker push "${DOCKER_REPO}:${version}" command now fails with:

The push refers to repository [docker.io/vladgh/testautobuildhooks]
73046094a9b8: Preparing
73046094a9b8: Layer already exists
denied: requested access to the resource is denied
unauthorized: authentication required

Did anything change in the past few days with the way Docker Hub runs the build process?

We’re having the exact same problem on our automated builds. We tag our branches with a datestamp. At first we thought the problem was in the date command. But,for testing, I simplified it to the following and we still get the same error across multiple repos.


Error Message:

denied: requested access to the resource is denied
post_push hook failed! (1)

I opened this issue https://github.com/docker/hub-feedback/issues/1611 on GitHub

The issue was fixed a few hours ago.

Ours was still failing as of 2 hours ago … trying again now.

Hi there, maybe you guys need to docker login first
