After testing has completed I’d like to take my image:latest image and create a release tag like image:1.3.1. Is it possible to tag from dockerhub to dockerhub without doing a pull, tag, and push? I don’t have any reason to download and upload it other than to change the tag.

No, it’s not possible. Do you see how this could wreak havoc with access control levels if allowed? Just because I have access to registry A and B, does not imply that registry A or B should have access to the other. Check out the docker tag command, which might well solve your problem in the fi…

I’m not following your answer. For a single registry I can do a pull, tag (no build), and push. I’d like to do exactly that without pulling and pushing. I’m not insterested in crossing two registries. I run create and upload my :latest on one server, and if they pass the tag logic is on another serv…

If the layers already exist and you docker push with a different tag Docker will figure out there is nothing to push and report Layer already exists for those layers. Why do you need to tag and push from a different server than the one you originally build and push on? Wouldn’t it be easier to just…

Why not just tag the first image with the unique tag in the first place?

Would loved to have found a solution on this thread. Such is life. @nathanleclaire because it’s common to want to rely on a specific type of version. Perhaps the idea is to always be using the “latest” version of some internal published thing by another team. One wants to know immediately when the …

@nathanleclaire I would love to see an update here. I have the same problem. In my environment, CI/CD produces an image, tags it dev, and pushes it to a repository. When QA wants an update to their environment, each image is pulled by the tag dev, tagged as qa, and pushed back to the repository. Aft…

Resurrecting the thread - for those still interested, I found this: https://dille.name/blog/2018/09/20/how-to-tag-docker-images-without-pulling-them/

The use case is straightforward: One: Git tags can be applied to a SHA at any time, and in particular long after that SHA has passed CICD. In particular it is common that not every git SHA will be tagged with a semantic version tag and it is relatively common that the version that needs to be shipp…

In a CI/CD flow I build the image in one travisci step and deploy it to a test server. Then in a second travisci step I run some tests on the test server and if they pass I want to tag the :latest to :deployable-timestamp. The second step doesn’t have the image so I’m downloading, tagging, and uploading just to accomplish the tag.
