All r/ links in hub get 404 error in rancher (but also other repos)

[StefanSa]

Hi there
i just tried to install rke2 and i get a 404 error for all rancher images.
Is there similar problem as already happened here ?
#2196

Do you have an URL that fails? I just tried first from their list of repositories (at https://hub.docker.com/u/rancher), and that one seemed to work; https://hub.docker.com/r/rancher/hardened-calico

Hi @thaJeztah
these for example:
https://index.docker.io/r/rancher/rke2-runtime

Pulling runtime image index.docker.io/rancher/rke2-runtime:v1.22.6-rke2r1
FATA[0001] chmod /var/lib/rancher/rke2/data/v1.22.6-rke2r1-e6c1502b55cd/bin: no such file or directory

Thanks! Let me check internally if something is known

[thaJeztah]

Looks like the image itself is there, so seems like it's something in the presentation (not sure why you get that error though);

docker manifest inspect rancher/rke2-runtime:v1.22.6-rke2r1

      },

      }
   ]
}

@StefanSa a colleague noticed (I overlooked it) that you're using index.docker.io for the domain, not hub.docker.com; using hub.docker.com (which is the correct domain for the Docker Hub UI) looks to work; https://hub.docker.com/r/rancher/rke2-runtime

(Not sure why index.docker.io also shows the hub front-end, but this could be related to some redirects)

@thaJeztah
Thanks for the info, it is generated by the rke2 install script itself, i have no influence on it.

Pulling runtime image index.docker.io/rancher/rke2-runtime:v1.22.6-rke2r1

[thaJeztah]

Right, but that's the registry URL used to pull images (which is separate from the UI - notice that the Pulling image .. does not have the /r/ in the path as well).

docker pull index.docker.io/rancher/rke2-runtime:v1.22.6-rke2r1
v1.22.6-rke2r1: Pulling from rancher/rke2-runtime
a46628218d70: Pull complete
Digest: sha256:6121296231a82bbdf6d077ee08be5882f7ac162bbf350436b5972627f3cb1645
Status: Downloaded newer image for rancher/rke2-runtime:v1.22.6-rke2r1
docker.io/rancher/rke2-runtime:v1.22.6-rke2r1

Although the correct variant should be docker.io (without index. - the index.docker.io subdomain for references is mostly for backward compatibility; they're normalized internally in the docker engine)

docker pull docker.io/rancher/rke2-runtime:v1.22.6-rke2r1
v1.22.6-rke2r1: Pulling from rancher/rke2-runtime
Digest: sha256:6121296231a82bbdf6d077ee08be5882f7ac162bbf350436b5972627f3cb1645
Status: Image is up to date for rancher/rke2-runtime:v1.22.6-rke2r1
docker.io/rancher/rke2-runtime:v1.22.6-rke2r1

[thaJeztah]

So, I guess you arrived there by pasting that image name in your browser; https://index.docker.io/rancher/rke2-runtime:v1.22.6-rke2r1

I think there's some redirects missing for those to redirect to the corresponding Docker Hub UI URL (I recall I opened an internal ticket for that, but it's still in the backlog)

[StefanSa]

Exactly, but is that why the pull fails ?

[thaJeztah]

No the pull itself succeeds for me, but perhaps there's some step after pulling that's happening? the error;

chmod /var/lib/rancher/rke2/data/v1.22.6-rke2r1-e6c1502b55cd/bin: no such file or directory

Seems to be that either a file is missing, or the path is incomplete (/bin could be pointing to a directory)
