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/).

Click the image you want to export.
Click Export Image in the action menu to the right of the target image.
Export can be done in two ways, and the format is exported in OCI format.
- Object Storage Bucket: Export as an Object Storage Bucket within the logged-in Tenancy. Select the target compartment and bucket.
