Upload an image

To register an external container image in the internal registry, follow these steps.

1. Save the image to upload as a tar file using docker save.

   docker save -o my-image.tar my-registry.com/my-image:tag

   A single tar file can contain multiple images.

   docker save -o multi-image.tar image1:tag1 image2:tag2

2. Click the + Upload Image button at the top-right of the External Images list page.

3. In the upload dialog, drag & drop the tar file or click the file-select button to choose a file.

②	Upload start button. Enabled after a file is selected.

4. Click the Upload button. The upload proceeds as a chunked upload, and you can see the progress in the status bar.

5. When the upload completes, the status changes from Importing to Completed. After completion, you can select the image from the 'Uploaded Images' group when creating a Serving or a Lab.

Delete an image

In the list, click the Delete button for the image you want to remove. A confirmation dialog appears before deletion.

Delete carefully

Deleted images are also removed from the internal registry. If any Serving or Lab is using the image, those workloads may be affected.
