Are SAS Viya images re-downloaded from the Container Registry each time the EKS cluster is started?

[EyalGonen]

Hi experts,

Sorry for the novice question... When I deploy SAS Viya to EKS on AWS (as an example) using the SAS CR as my container registry, everything works fine. Then I shut down the EKS cluster and start it once again and I also start all the SAS pods using the "sas-start-all" cronjob. In this case, are the SAS images for all SAS pods downloaded once again from SAS CR or are they cached somewhere in AWS/EKS and no access to SAS CR is required for the pods to start?

Thanks,

Eyal

When the EKS cluster is stopped the underlying VMs are removed along with the downloaded images, so when starting the cluster you have fresh VMs that must re-download the images.

If you want these images to be stored in AWS instead you would use an AWS container registry (ECR), and use mirror-manager to copy the images from the SAS CR to the AWS ECR, then update your deployment assets to use the mirror registry instead.
