Listing images

The following command can be used to show a full list of Docker containers, irrespective of state. If you want to see only the running containers omit the -a (stands for all) option:

docker ps -a

The -f or --filter flags are applicable for the preceding command. -f or --filter, when used along with docker ps [OPTIONS], the list of containers, will be filtered as per the filtering condition provided along with this flag. For example, the following command shows details of the container matching the name:

docker ps --filter name=nostalgic_norman.

A few more valid flags for the filter option are exited=0, status=paused, and ancestor=windowsservercore. The following options are also valid while listing images:

• -n: Shows the number of containers in any state
• -l: Shows the latest container created
• -s: Shows total file size

The usage is very similar to the filter flag shown previously.
