[Bug] eksctl utils update-coredns image interpolation broken

[Guillermogsjc]

when deploying k8s 1.28 with eksctl v0.160.0, coredns will not arrive because of Error: InvalidImageName, with a more specific message:

Failed to apply default image tag "602401143452.dkr.ecr.ap-northeast-2.amazonaws.com/eks/coredns:v1.10.1-eksbuild.3%!(EXTRA string=602401143452, string=eu-west-1, string=amazonaws.com)": couldn't parse image name "602401143452.dkr.ecr.ap-northeast-2.amazonaws.com/eks/coredns:v1.10.1-eksbuild.3%!(EXTRA string=602401143452, string=eu-west-1, string=amazonaws.com)": invalid reference format

looks like an issue related with string interpolation on the image name

I can see two replicasets created for coredns, one with that bad interpolated image name

I guess that this command

eksctl utils update-coredns --approve --cluster ${CLUSTER_NAME}

that it is being executed in the pipeline right after creation of nodegroups, is patching the image name with the bad interpolated string.

eksctl version: 0.160.0
kubectl version: v1.28.1-eks-43840fb
OS: linux

@AdamDomagalsky, the fix was released in https://github.com/eksctl-io/eksctl/releases/tag/v0.162.0-rc.0, and not 0.161.0.
