Release notes for storage-operator - Container Service for Kubernetes

Container Service for Kubernetes (ACK) provides multiple storage components to enhance storage capabilities, such as automatic expansion of volumes, modification of disk specifications, and storage resource monitoring. The storage-operator component is used for unified lifecycle management of these components. This topic describes the usage instructions and release notes for storage-operator.

By default, storage-operator contains the following storage components:

storage-cnfs is responsible for the features provided by CNFS.
storage-controller is responsible for disk configuration modification and cross-zone migration.
storage-auto-expander is responsible for the auto scaling of volumes.

Usage notes

For more information about how to use the storage-operator component, see Manage the storage-operator component.
