I'm not sure who updates the fedora image in the Docker hub. CC'ing dusty since he knows the base images much better than me. I'm the main point of contact for both the registry.fedoraproject.org one and the one on Docker Hub. The reason these are different is that the way you submit Docker Hub official images is through the docker-library/official-images[0] repo on GitHub. In there you provide a Dockerfile and a rootfs. The images themselves are actually built on Docker's systems. We don't have a choice in this, that's just how its done and to update a container image you file a pull request. We have this process documented here[1], but it basically boils down to: pull the image tarball from koji, strip the metadata and extract the rootfs tarball, add to the Dockerfile, force commit to github. On the contrary, the registry.fedoraproject.org images comes directly from Fedora systems and we simply pull the container image tarball from koji, import it to docker, tag it, and push it. (There's a script so we don't do it by hand, but that's what it does) Ultimately the source of both originates from the image builds in koji which use image-factory[2]'s docker image plugin to produce the resulting artifact. However, we have to unpack it and push only the rootfs up to Docker Hub. [0] - https://github.com/docker-library/official-images [1] - https://github.com/fedora-cloud/docker-brew-fedora [2] - http://imgfac.org/ Couldn't the docker.io/fedora be just redirect to registry.fedoraproject.org? Not to the best of my knowledge, no. That's not how any of the official base images on Docker Hub are handled except for certain software vendors that Docker has contracts in place to allow such an agreement. This message is a reminder that Fedora 26 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '26'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 26 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. I guess, this one is likely WONTFIX, right? Fedora 26 changed to end-of-life (EOL) status on 2018-05-29. Fedora 26 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
Description of problem: I've recently used some layered image on top of fedora:26 and then I did docker pull fedora:26 and new image was pulled. Which was surprising but then I realized that the layered image actually uses registry.fedoraproject.org/fedora:26 as its base image. So I wondered if the images are the same or not. It turns out, that already the metadata are different.

Or much smaller differences, for example the Cmd and Labels should be the same. And of course ideally the Layers as well. Additional info: Please reconcile the Fedora images found in various places. Also, it's be good to include information about how the image was built (from which source) and how issues with those images (like this one) should be reported. The registry.fedoraproject.org/fedora:26 says "Comment": "Created by Image Factory", but with no indication what it is, where it lives, and what was the exact source for this base image.
