@bergtwvd, thanks for bug report. The same bug was also reported in #42.

Looks like Cmd field is empty in docker registry response.
Can you share response from you docker registry on this command:

curl -H "Accept: application/vnd.docker.distribution.manifest.v2+json" $REGISTRY_URL/v2/msaas/pi-crc/manifests/5.3.0.0L

changing $REGISTRY_URL to your registry URL. You may also need to temporarily disable authentication on your docker registry to allow the execution of this request.

Thanks for output, @bergtwvd.
What are your docker engine and docker registry version?

One more question, can you please share output of the command:

@bergtwvd, thanks for the help, easy fix should be sufficient.
It's available in the latest version, can you confirm if it works for you?

bergtwvd · 2016-07-05T14:26:21Z

Is it already available as a container image?
I just pulled lastest from the Hub, and still see the same stacktrace. But I suppose this is v0.1.1 and your fix is in v0.1.2.

mkuchin · 2016-07-06T01:35:08Z

Yes, fix already available in hyper/docker-registry-web:latest.
That's strange, I can't reproduce this bug on latest version with your JSON manifest.

bergtwvd · 2016-07-06T13:54:17Z

What I did is the following:

I removed all files under examples/nginx-auth-enabled/db and examples/nginx-auth-enabled/registry.
docker pull hyper/docker-registry-web
docker-compose up
open a webbrower, login as admin, and add a user X wil push/pull permissions
docker login localhost:443 (suppying username X / password X)
docker push localhost:443/msaas/pi-crc:5.3.0.0L
open webbrowser, login as X, and navigate to Home > msaas/pi-crc > 5.3.0.0L

Console shows:

mkuchin · 2016-07-06T16:56:40Z

Thanks for patience. I'd added commit hash tracking in the build, to make sure we are talking about the same version.

Can you pull the latest version, please and confirm that you can see such log message on startup:

 [localhost-startStop-1] INFO  conf.BootStrap  - Starting registry-web ver. 0.1.2-SNAPSHOT-4cc4d250a0afdcc33e4368be55688a7ad9ed5ac8

bergtwvd · 2016-07-06T19:22:02Z

I am feeling really ashamed. I just looked in the docker compose file, where the image was still pointing to v0.1.0. I have changed this to latest, and the problem has gone.
Sorry for all he confusion and waste of time :-(.

mkuchin · 2016-07-07T00:43:56Z

No worries. Thanks for taking the time to contribute to the project!
