How to see docker image contents

Question

I did a docker pull and can list the image that's downloaded. I want to see the contents of this image. Did a search on the net but no straight answer.

Answer 1

You can just run an interactive shell container using that image and explore whatever content that image has.

For instance:

docker run -it image_name sh

Or following for images with an entrypoint

docker run -it --entrypoint sh image_name

Or, if you want to see how the image was build, meaning the steps in its Dockerfile, you can:

docker image history --no-trunc image_name > image_history

The steps will be logged into the image_history file.
