Why can't I delete images labeled “none“ in Container Station?
Applicable Products
Container Station 3.x and later
Scenario
After updating Container Station to 3.0, you may see numerous images listed with a Repository or Tag labeled as <none>.
Attempting to delete these images results in the following error.
Error message: failed to remove image sha256......[Error response from daemon: conflict: unable to delete img_id (cannot be forced) - image has dependent child images]
Explanation
Starting with Container Station 3.0, the system directly shows all image files created by users. This includes images that do not have a specific repository or tag, which are displayed as <none>. The generation of these <none> images is normal Docker behavior and can happen when you create, pull, or edit Docker images. To remove the images safely, you need to first find and remove their dependent child images.
