Using Docker – Managing Local Images

Local images are images that are stored by Docker on a local disk, so
there is no need to download them from the Image Catalog.

An image becomes local in the following situations:

• You have selected any version (tag) of an image and the image has
  started downloading. If you either later run a container or cancel
  running (in the Settings screen), the image is saved locally.
• You upload an image to Docker catalog in Plesk (Upload Image in
  Docker Image Catalog).
• You have created a custom image from a container (see Creating
  Images with Custom Settings).
• You have built an image using the command line interface.

If Docker has at least one downloaded version from a group of versions
belonging to an image, this image is marked Local image in the
catalog. Run (local) means that the latest version was already
downloaded. Plesk also shows how many local images exist for a product.

To view local images and remove outdated local images:

1. Go to Docker > Docker Image Catalog.

2. To find all local images, click the arrow next to the search box and
   select Local in the Repository filter.

3. To view all local images of a specific product, click the link under
   the product name. All local images’ tags and occupied disk space will
   be displayed.

4. To remove all images, click Clean All Images.

5. To remove a specific image, click the Remove icon
   next to the image that you want to remove.
