Deleting Images and Image Sources

When an image source is selected, users can see all existing images created using that source listed. On this list is a column that says Usage which contains information about how many containers are currently using this image.

If any container is using an image, that image cannnot be deleted.

Deleting Individual Images

There are three ways to delete individual images:

Select the image from the list which opens the image modal and use the delete form there.
Use the checkbox available in the row and then the delete button.
Prune Unused Images, which will remove all unused images older than 15m.

Deleting Image Sources

Once all images are removed from an image source, that image source can be deleted through the form on the settings page.

Some Stacks Use Image Sources

Be careful when deleting image sources. In stacks there are two types of image source that can consume an existing image source: existing and cycle-source. If a user deletes that referenced image source it will cause the stack builds to fail.
