Viewing Docker Image Contents
Snippet
Posted by kitt at 11:16 on 22 February 2021
Okay, so, you want to view the contents of a Docker image. Do not start / run the image to view its contents if you don't know what the contents are.
Instead, use docker create:
The docker create command creates a writeable container layer over the specified image and prepares it for running the specified command. The container ID is then printed to STDOUT . This is similar to docker run -d except the container is never started.
# create but don't run the the image docker create --name="thisisatempname" image:tag # run export to view the contents, pipe to the tar command in table of contents mode and paginate with less docker export thisisatempname | tar t | less # clean up docker rm thisisatempname
