eksctl tool, I created an EKS cluster with 5 nodes. My application's docker images are stored in ECR registries in the same region. I deployed my kubernetes cluster and everything has been happy for the past 6 weeks or so.
This morning, I came in and found 3 pods were in an
ErrImagePull state. Using
kubectl describe pod <pod name>, I found the error:
Failed to pull image "<ECR REGISTRY>/<IMAGE>": rpc error: code = Unknown desc = Error response from daemon: Get <ECR REGISTRY>/<IMAGE>: no basic auth credentials
My understanding of EKS and ECR is that I don't need a pull secret (and I haven't used one for any of the other running pods) so my guess is that some process or docker image on that node died but I can't find any docs on this.
Update: I forgot all about this question. When I created the original node group, I failed to include the
--ssh-access flag which prevented me from getting onto the node and see if a kubernetes process had failed. I never found the actual solution; I simply added a taint to the problem node, created a new node, and went about my business. I'm still trying to find time to spin up a new node group with ssh access.
