The easiest way to list Docker images is to use the “docker images” with no arguments. When using this command, you will be presented with the complete list of Docker images on your system. Alternatively, you can use the “docker image” command with the “ls” argument.
Also, can you inspect a docker image?
You can inspect a suspect image by exporting it to an archive and browsing through its content. This keeps the image inert, preventing malicious content from being run, while providing a complete view of the filesystem it would create in a container.
Accordingly, how do you expose a docker container?
How to Expose Ports in Docker

What is a docker digest?
Docker digest is provided as a hash of a Docker image supported by the Docker v2 registry format. This hash is generated as sha256 and is deterministic based on the image build.
What is docker image layer?
Each layer is an image itself, just one without a human-assigned tag. They have auto-generated IDs though. Each layer stores the changes compared to the image it’s based on. An image can consist of a single layer (that’s often the case when the squash command was used).
What is ECR manifest?
Amazon ECR image manifest conversion
When you push and pull images to and from Amazon ECR, your container engine client (for example, Docker) communicates with the registry to agree on a manifest format that is understood by the client and the registry to use for the image.

Where does docker for Windows store images?

Where is docker config JSON?
The default location of the configuration file on Windows is %programdata%\docker\config\daemon. json . The –config-file flag can be used to specify a non-default location.
