I can't find my Docker image after building it

问题:

I'm new to Docker, so please allow me to describe the steps that I did. I'm using Docker (not Docker toolbox) on OS X. I built the image from Dockerfile using the following command
sudo docker build -t myImage .

Docker confirmed that building was successful.
Successfully built 7240e.....

However, I can't find the image anywhere. I looked at this question, but the answer is for Docker toolbox, and I don't have a folder /Users/<username>/.docker as suggested by the accepted answer.

You would be able to see your docker images by the below command:

docker images

And to check which all containers are running in docker:

docker ps -a

回答2:

Command to list the docker images is :

docker images

The default docker images will show all top level images, their repository and tags, and their size. An image will be listed more than once if it has multiple repository names or tags.

In addition to the correct responses above that discuss how to access your container or container image, if you want to know how the image is written to disk...

Docker uses a Copy on Write File System (https://en.wikipedia.org/wiki/Copy-on-write) and stores each Docker image as a series of read only layers and stores them in a list. The link below does a good job explaining how the image layers are actually stored on disk.
