Bug: k8s.gcr.io (registry) hardcoded for cluster-autoscaler

[drmaciej]

Expected Behaviour

No exception thrown, both old and new registry handled.

Current Behaviour

Snippet of the output when running eksupgrade drmaciej-cluster 1.26 ap-southeast-2 --preflight

Cluster Autoscaler exists
cluster-autoscaler pod is running
Error occurred while checking for the cluster autoscaler - Error: list index out of range
Pre flight unsuccessful because of the following errors: ['To upgrade please run the code with --force flag ', 'Error occurred while checking for the cluster autoscaler list index out of range']
Pre-flight check for cluster drmaciej-cluster targeting version: 1.26 failed!

It appears that the exception is thrown in

                version = (
                    i.spec.template.spec.containers[0]
                    .image.split("k8s.gcr.io/autoscaling/cluster-autoscaler:v")[1]
                    .split("-")[0]
                )

because my image is set to registry.k8s.io/autoscaling/cluster-autoscaler:v1.25.0.

k8s.gcr.io is about to be sunset and new images are not published there. For instance, the latest publish CA images are on the new registry already (see https://github.com/kubernetes/autoscaler/releases)

@drmaciej I am also facing the similar issue with the above problem as my image is set to registry.k8s.io/autoscaling/cluster-autoscaler:v1.21.0 .

[ricky1-gupta]

@bryantbiggs I tried without using the pre-flight checks also but its not working. eksupgrade cluster_name cluster_version region ERROR: Error occurred while checking for the cluster autoscaler - Error: list index out of range Pre flight unsuccessful because of the following errors: ['To upgrade please run the code with --force flag ', 'Error occurred while checking for the cluster autoscaler list index out of range'] Pre-flight check for cluster NonProd-Movies-Cluster targeting version: 1.21 failed!

112 removes the pre-flight checks which is where this issue is coming from https://github.com/aws-samples/eks-cluster-upgrade/pull/112/files#diff-b9aeab33037539343fdb6eb6a9360f1fcfeab0008902d6c840aea7666ef999ea

@bryantbiggs Can share with the command for updating the same . As I uninstall and installed it again but the version is still 0.8.3 .

[bryantbiggs]

Once a new release is created, you can upgrade to the next version which will not have this issue

[ricky1-gupta]

@bryantbiggs When will you release it as I need it asap.

we should be able to get a release out today - cc @mbeacom
