@GiedriusS @fpetkovski Thoughts? I wanna use to identify when the key access was revoked so we can return an well defined error from store gateway: on cortex: cortexproject/cortex#5420 |

Could we return a newly defined ErrInvalidCustomerManagedKey error and use errors.Cause to identify it? This way a client does not need an instance of the bucket in order to distinguish between error types.

I missed that we already have IsObjNotFoundErr, so I guess this should also be fine.

Some bucket like s3 and Azure implementations allows encrypting the block storage with customer managed keys and the permissions to this keys can be revoked anytime.
This PR is creating a extra method (
IsCustomerManagedKeyError) when the key permission got revoked by the key owner and so the upstream can handle it appropriately (cortex,thanos)Related to: cortexproject/cortex#5420
As a first step only the s3 implementation is identifying such errors but i can follow up with the azure one.
