I have a Rancher custom cluster and I’d like to set the ‘etcd Snapshot Backup Target’ to backup to S3. I believe I’ve setup proper permissions in IAM and configured Rancher accordingly but I’m not seeing any backups showing up in the bucket. I’ve enabled logging for the bucket and I don’t see Rancher even attempting to put anything there, so I’m assuming I’m hitting a problem in Rancher. Per the documentation here:
When referencing requirements for S3, it sounds like the assumption is that the cluster is running on EC2 instances. Is it possible to backup etcd snapshots from a custom on-prem cluster to S3?
Are there any logs Rancher side I can look at to gain some insight on why this isn’t working?
