Container Object Storage Interface API

This repository hosts the API defintion of the Custom Resource Definitions (CRD) used for the Container Object Storage Interface (COSI) project. The provisioned unit of storage is a Bucket. The following CRDs are defined for managing the lifecycle of Buckets:

• BucketClaim - Represents a request to provision a Bucket
• BucketClass - Represents a class of Buckets with similar characteristics
• Bucket - Represents a Bucket or its equivalent in the storage backend

The following CRDs are defined for managing the lifecycle of workloads accessing the Bucket:

• BucketAccessClass - Represents a class of accessors with similar access requirements
• BucketAccess - Represents a access token or service account in the storage backend

NOTE: All of the APIs are defined under the API group objectstorage.k8s.io.

For more information about COSI, visit our documentation.
