In this tutorial we will discuss about Docker image layers and how intermediate layers are created, and how dangling images are destroyed. When you pull a Docker image, you will notice that it is pulled as different layers. Also, when you create your own Docker image, several layers are cre...

Fixed docker load causing pool corruption which could some subsequent image related operations. Fixed not being able to reference images via truncated digest with a sha256: prefix. Fixed docker images (without --all) showing intermediate layers (created by the legacy classic builder). Fixed docker...
Show Docker image contents broken down by layer As you select a layer on the left, you are shown the contents of that layer combined with all previous layers on the right. Also, you can fully explore the file tree with the arrow keys. ...
A Docker image is an executable file that's used to build a Docker container. Delve into its various layers, use cases, anatomy and creation process.
View image layersYou can look at the layers that make up an image. Run the docker image history command to see the command that was used to create each layer within an image.Use docker image history to see the layers in the getting-started image that you created earlier in the tutorial....
