Docker摘要提取不适用于Docker 1.13.1和Artifactory 5.0.1

Question

Docker pull by digest fails with Error response from daemon: received unexpected HTTP status: 500 Internal Server Error when Artifactory is used as Docker registry.

The problem causes docker service creation operations to fail if latest tag is used. I have been using Artifactory as Docker registry for about 9 months with no problem. After I upgraded Docker to version 1.13.0 (and to version 1.13.1 later), I started to get No such image: ... errors while creating services with tag latest or with no tag. Artifactory logs showed that pulling is made by digest while docker service is being created from latest images. Upgrading to the latest version of Artifactory(5.0.1) did not worked.

I found an open issue regarding the problem: https://www.jfrog.com/jira/browse/RTFACT-10543

Pulling images by digest might not be a popular operation, but docker service creation from latest image should be very common practice. It is interesting that a few complaints exist about the problem. That is why I started to think whether the problem is somehow related with my Artifactory configuration.

I upgraded to the latest version of Docker (17.03.0-ce) and Artifactory (5.1.0) with no luck.

UPDATE 2

The problem still exists with Artifactory 5.1.2.

UPDATE 3

It seems that Artifactory does not handle recent changes of Docker regarding image tags. Simply put:

• docker service create ... pulls images by digest (foo@sha256:aabbff11)
• When pulling an image by digest (foo@sha256:aabbff11), no tag is created, because the same digest can be shared by different tags.
• Artifactory expects a tag and throws NPE while creating services or pulling images by digest.

There are active discussions in Docker community:

• [1.13] starting swarm services results in images with <none> tag #28908
• docker stack deploy creates no tags #31574
• Docker SHA-based (digest) pulls should respect and preserve image tag(s) #31656

Here are the simple test cases showing that docker run --name=busybox busybox:1.26.2 sleep 60 creates tag 1.26.2, while docker service create --name=busybox busybox:1.26.2 sleep 60 does not. Also test cases show that Artifactory does not handle the cases where the tag is <none> .

RTFACT-10543 fixed with Artifactory 5.2.1 release. I confirmed Artifactory happily handles null tag now.

Service creation problem has also been resolved with this fix: https://github.com/moby/moby/issues/28908

Answer 1

It looks like you are indeed facing the issue you mentioned: RTFACT-10543 .

As you can see in the JIRA issue, this issue is still open (at the time this answer is written). If you want to promote it, I suggest you to up-vote it.
