will there be any workarounds for v1.25 or v1.26? the helm chart with a1CompatibilityDaemonSet=true tries to pull the v1.26.0-a1compat tag which doesn't exist.

[AndrewSirenko]

Hi @calvinbui, thank you for reaching out about a1compat for v1.25 and 1.26.

I have been working with EKS to try to find out why public.ecr.aws/ebs-csi-driver/aws-ebs-csi-driver:v1.25.0-a1compat and public.ecr.aws/ebs-csi-driver/aws-ebs-csi-driver:v1.26.0-a1compat don't exist. I will update you later today (by 8pm EST).

If you urgently need to unblock yourself, you can try replacing the default ecr-public image repository with registry.k8s.io/provider-aws/aws-ebs-csi-driver

The registry.k8s.io/provider-aws/aws-ebs-csi-driver:v1.26.0-a1compat image exists.
