I was trying to deploy a nexus app in a k3s cluster, but I'm getting some errors as below:
Warning FailedCreatePodSandBox 6s (x7 over 81s) kubelet Failed to create pod sandbox: rpc error: code = Unknown desc = failed to get sandbox image "rancher/mirrored-pause:3.6": failed to pull image "rancher/mirrored-pause:3.6": failed to pull and unpack image "docker.io/rancher/mirrored-pause:3.6": failed to resolve reference "docker.io/rancher/mirrored-pause:3.6": failed to do request: Head "https://registry-1.docker.io/v2/rancher/mirrored-pause/manifests/3.6": dial tcp: lookup registry-1.docker.io on 172.12.8.8:53: no such host
Basically, I pull the docker images and imported to k3s, and in the deployment.yaml, also I set the imagePullPolicy to Never, but I'm still getting the same error.
The reason that I was trying to do this is because the cluster has no internet access directly, I have to pass through a proxy. (Also I try to set the proxy in k3s.service and k3s.server.env and nothing changed).
