The easy approach is to use:

docker ps --size

But this will output a long table with columns:

Container ID
Image
Command
Created
Status
Ports
Names
Size

Let’s refine the command

More likely, you’re just curious about these columns:

Container ID
Names
Image
Size

In order to do so, just run:

docker ps -a --size --format "table {{.ID}}\t{{.Names}}\t{{.Image}}\t{{.Size}}"
