Docker - list only container ids

In this short article, we would like to show how to list ids of run containers in Docker.

Quick solution (run following command):

docker ps -q

Output:

d76423e8e259
f44b6ffcee6a
25605bf8dc3f
c14692b929b2
8867d0ac1ed1

Alternative solution

The approach presented in the section cuts first field that is Container ID and removes column heading.

Command example:

docker ps | cut -f 1 -d " " | tail -n +2

Output:

d76423e8e259
f44b6ffcee6a
25605bf8dc3f
c14692b929b2
