kubernetes-sigs/container-object-storage-interface#402 · 1 comment · Opened Sep 16, 2026
Before we generate the bucket ID, we should validate the BucketClaim ref. Currently, this validation is done at the beginning of `dynamicProvisioning()` and `staticProvisioning()` for either case, but we would do the best service to users by moving this validation before we make any RPC calls. That way, we don't proceed to `generateBucketId()` (which might in the worst case provision a backend resource) unless we know the Bucket state is actually valid. Open
