LFD256 Lab 3.2 using V 2022-11-23
Looking for advise.
My control plane and worker node are configured:
- has podman installed
- $repo env = the cluster IP from
kubectl get svc | grep registry
( w/ :5000) curl $repo/v2/_catalog
on both control node and worker node output the simpleapp in the registry- /etc/containerd/config.toml & /etc/containers/registries.conf.d/registry.conf
on both control node and worker node are configured with this cluster IP
on control node I ran:
sudo podman build -t simpleapp . sudo podman tag simpleapp $repo/simpleapp sudo podman push $repo/simpleapp
on worker node I ran as a debug step sudo podman pull $repo/simpleapp
- and this was successful!
The wild thing is that on my worker node i successfully pull using the commandsudo podman pull $repo/simpleapp
My issue is when running:kubectl create deployment try1 --image=$repo/simpleapp
my output is:
Events: Type Reason Age From Message ---- ------ ---- ---- ------- Normal Scheduled 15m default-scheduler Successfully assigned default/try1-6568894f-6p9vp to ip-172-31-4-176 Warning Failed 14m (x6 over 15m) kubelet Error: ImagePullBackOff Normal Pulling 14m (x4 over 15m) kubelet Pulling image "10.102.69.34:5000/simpleapp" Warning Failed 14m (x4 over 15m) kubelet Failed to pull image "10.102.69.34:5000/simpleapp": rpc error: code = Unknown desc = failed to pull and unpack image "10.102.69.34:5000/simpleapp:latest": failed to resolve reference "10.102.69.34:5000/simpleapp:latest": failed to do request: Head "https://10.102.69.34:5000/v2/simpleapp/manifests/latest": http: server gave HTTP response to HTTPS client Warning Failed 14m (x4 over 15m) kubelet Error: ErrImagePull Normal BackOff 27s (x65 over 15m) kubelet Back-off pulling image "10.102.69.34:5000/simpleapp"

Hi @sebastianvaldez01, @tstaffordsmith,
The error you are experiencing is caused by recent upstream changes. We will post an update once they get resolved or with a possible workaround.
Regards,
-Chris0 -
Is the workaround available yet?

@chrispokorni, upstream changes with what provider? I have been able to successfully create the registry, push an image, and pull from it without encountering an error.

I think you are facing the same issue as I did. I provided a fix in a response to this thread : https://forum.linuxfoundation.org/discussion/862401/lfd259-course-updated-to-v1-25-1-11-8-2022#latest
