Image rancher/mirrored-flannelcni-flannel:v0.20.2 is not (yet?) available on Docker Hub

[starypatyk]

Expected Behavior

When deploying flannel on a new k8s cluster with:

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

the kube-flannel pod(s) should start.

Current Behavior

The kube-flannel pod(s) do not start with the following error message:

Failed to pull image "docker.io/rancher/mirrored-flannelcni-flannel:v0.20.2": rpc error: code = Unknown desc = Error response from daemon: manifest for rancher/mirrored-flannelcni-flannel:v0.20.2 not found: manifest unknown: manifest unknown

Possible Solution

Apparently the 0.20.2 version of the image is not (yet?) available on Docker Hub.

Your Environment

I am trying to deploy a local k8s development cluster using kubeadm (1.23) and suggested method of flannel installation.

v0.20.2 it's still on pre-release.
I suggest to use the latest released version and not the one on the master

Yes, this worked for me.

@rbrtbnfgl - this worked for me as well. 👍

Probably would be good to change the readme, to instruct people to use the latest released version rather than master. 😉

Thank you

Is there a canonical URL for the current released (ie, not pre-release) manifest that is stable across releases? Thanks!

[rbrtbnfgl]

The new image is available now. There was some delays from the release to the image publishing this time.

@rbrtbnfgl - Thanks for updating the documentation. 🙇 Agree that such approach provides better stability. 👍
