Push is denied in automated build hooks

[vladgh]

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: https://docs.docker.com/docker-cloud/builds/advanced/

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

The push refers to repository [docker.io/vladgh/testautobuildhooks]
73046094a9b8: Preparing
73046094a9b8: Layer already exists
errors:
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?

Hi @vladgh , this issue should have been fixed ~8hrs ago. Are you continuing to see problems if you retry?

[vladgh]

Last time I tried was about 8 hours ago 😬 before going to bed. I can confirm it works now. Thanks for the very fast response.

I am still facing a similar problem. I use TravisCI to build Docker images and push them to public docker hub repo. This can be observed in the Travis build log below. Each build job compiles one docker image tag and pushes it.
https://travis-ci.org/BWibo/3dcitydb-web-map-docker/builds/419878622
For instance in job #20.1 I get following error (line 553+):

$ ./travis.sh deploy
bwibo/3dcitydb-web-map:devel-v1.1.0
Login Succeeded
The push refers to a repository [docker.io/bwibo/3dcitydb-web-map]

The same happens with the other images in the other build jobs.
I just tried building the image locally on my computer and I get the same error when trying to push to DockerHub.

Any suggestions?
Thx in advance.

If you are not using the Hub autobuilds this is a different issue. It does appear that you are not properly logged into your account if you are unable to push from your local machine. I would retry your docker login.

[BWibo]

Thx, this is what I just tried:

1. Change password on https://hub.docker.com/ and logout/login on the web page afterwards to see if ithe new pwd works
2. Logout from docker on my local machine using docker logout
3. Login again using docker login
4. Try to push image: docker push bwibo/3dcitydb-web-map:devel-alpine-v9.9.9 which results in denied: requested access to the resource is denied

Second, I delete the repo I am trying to push to manually from the DockerHub webpage.
Afterwards, something really strage happens. I build two different images: bwibo/3dcitydb-web-map:devel-alpine-v9.9.9, bwibo/3dcitydb-web-map:anotherTag
Pushing the first image seems to succeed:

$ docker push bwibo/3dcitydb-web-map:devel-alpine-v9.9.9
The push refers to repository [docker.io/bwibo/3dcitydb-web-map]

However, pushing the second image within the same shell session (without logout/login inbetween) fails:

Sorry for the bother, I just resolved the issue myself.
With pushing the new repo I exceeded the free private repo limit, which caused me failing to push. After setting the repo to public manully on the DockerHub web page pushing works as expected again.

It would be helpful to add a more informative error message when the push fails because reaching the limit of private repos.
