9.3 Custom Image Export/Import

Custom Image provides import and export functions. The Custom Image belongs to the Comparment within the Region, and to copy it to another Compartment or to another Region, it is exported to Object Storage and then imported again at the desired location.

For the description of creating a Bucket in Object Storage and pre-authentication, see [7. Using Object Storage] (/oci/chapter07/).
