Any idea if we can use aws farget as existing cluster install?

Hello,

I was trying to install the kotsadm app on eks with farget but its not getting persistent volume assigned to it.
Is there any restriction of KOTS to have EBS storage only ?

 Warning  FailedScheduling  58m   fargate-scheduler  Pod not supported on Fargate: volumes not supported: kotsadm-minio not supported because: PVC kotsadm-minio-kotsadm-minio-0 not bound

and none of them getting up.

I dont see any mentions of farget or ebs in replicated documentation, but i guess kotsadm-minio uses ebs for storage.

Hi @dmuley I’m not sure if kots will work on Fargate. In the past I’ve seen that typically the storage part is a potential problem. More info on how kots uses storage and options how to for example disable minio: About Selecting Storage Add-ons | Replicated Docs

Can you check the creation of the PV’s? I’m assuming that is where we might find the root cause.
