virtlet.cloud/ubuntu/16.04 #876

Hi @lukaszo, I'm new to virtlet and I have been facing the ErrorImagePull for 16.04 and I was wondering if there's any way to resolve this? I am able to reach the image using wget (https://github.com/onap/multicloud-k8s/blob/master/kud/deployment_infra/playbooks/configure-virtlet.yml#L39).

Here's some information: Normal Pulling 6m55s (x3 over 7m48s) kubelet, localhost pulling image "virtlet.cloud/ubuntu/16.04" Warning Failed 6m52s (x3 over 7m41s) kubelet, localhost Failed to pull image "virtlet.cloud/ubuntu/16.04": rpc error: code = Unknown desc = Error response from daemon: error parsing HTTP 404 response body: no error details found in HTTP response body: "{\"error\":\"Not Found\"}" Warning Failed 6m52s (x3 over 7m41s) kubelet, localhost Error: ErrImagePull Warning Failed 6m43s (x4 over 7m33s) kubelet, localhost Error: ImagePullBackOff

Hey @kishoreakhila

can you show output of kubectl get configmap -n kube-system virtlet-image-translations ? It looks like there is some issue with configuration of image translation and virtlet is trying to get http://virtlet.cloud/ubuntu/16.04 directly which of course doesn't work.

kishoreakhila commented 5 years ago

Oh yeah, I wasn't understanding why it wasn't prepending https://ubuntu.... to pull the image. kubectl get configmap -n kube-system virtlet-image-translations NAME DATA AGE virtlet-image-translations 1 24h This is all I got from running the command you asked me to. Please let me know if there's more information you'd want me to furnish.

lukaszo commented 5 years ago

Ah, sorry. kubectl get configmap -n kube-system virtlet-image-translations -o yaml we need to see what's inside.

It looks like you configured your cluster in a wrong way. Are CRIProxy and Kubelet configured correctly to use Virtlet? Virtlet is not trying to download the image but Docker.

kishoreakhila commented 5 years ago

Hi, @lukaszo apologies for the delayed response. I was away. Will reset my cluster and get back to you. Thank you for helping look into this.
