Get docker container id from container name

Question

What is the command to get the docker container id from the container name?

Answer 1

You can try this:

docker inspect --format="{{.Id}}" container_name

This approach is OS independent.

Answer 2

In Linux:

sudo docker ps -aqf "name=containername"

Or in OS X:

docker ps -aqf "name=containername"

where containername is your container name

explanation:

• -q for quiet. output only the ID
• -a for all. works even if your container is not running
• -f for filter.

Answer 3

If you want to get complete ContainerId based on Container name then use following command

 docker ps --no-trunc -aqf name=containername

Answer 4

The simplest way I can think of is to parse the output of docker ps

Let's run the latest ubuntu image interactively and connect to it

docker run -it ubuntu /bin/bash

If you run docker ps in another terminal you can see something like

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
8fddbcbb101c        ubuntu:latest       "/bin/bash"         10 minutes ago      Up 10 minutes                           gloomy_pasteur

Unfortunately, parsing this format isn't easy since they uses spaces to manually align stuff

$ sudo docker ps | sed -e 's/ /@/g'
CONTAINER@ID@@@@@@@@IMAGE@@@@@@@@@@@@@@@COMMAND@@@@@@@@@@@@@CREATED@@@@@@@@@@@@@STATUS@@@@@@@@@@@@@@PORTS@@@@@@@@@@@@@@@NAMES
8fddbcbb101c@@@@@@@@ubuntu:latest@@@@@@@"/bin/bash"@@@@@@@@@13@minutes@ago@@@@@@Up@13@minutes@@@@@@@@@@@@@@@@@@@@@@@@@@@gloomy_pasteur@@@@@@

Here is a script that converts the output to JSON.

Actually, the output is a bit more convenient to work with than that. Every field is 20 characters wide. [['CONTAINER ID',0],['IMAGE',20],['COMMAND',40],['CREATED',60],['STATUS',80],['PORTS',100],['NAMES',120]]

Answer 5

1. Get container Ids of running containers ::

   $docker ps -qf "name=IMAGE_NAME"
   
       -f: Filter output based on conditions provided
       -q: Only display numeric container IDs
   

2. Get container Ids of all containers ::

   $docker ps -aqf "name=IMAGE_NAME"
   
       -a: all containers
