Get docker container id from container name

Question

In Linux:

sudo docker ps -aqf "name=containername"

Or in OS X, Windows:

docker ps -aqf "name=containername"

where containername is your container name.

To avoid getting false positives, as @llia Sidorenko notes, you can use regex anchors like so:

docker ps -aqf "name=^containername$"

explanation:

• -q for quiet. output only the ID
• -a for all. works even if your container is not running
• -f for filter.
• ^ container name must start with this string
• $ container name must end with this string

You can try this:

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

This approach is OS independent.

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
   

The following command:

docker ps --format 'CONTAINER ID : {{.ID}} | Name: {{.Names}} | Image:  {{.Image}} |  Ports: {{.Ports}}'

Gives this output:

CONTAINER ID : d8453812a556 | Name: peer0.ORG2.ac.ae | Image:  hyperledger/fabric-peer:1.4 |  Ports: 0.0.0.0:27051->7051/tcp, 0.0.0.0:27053->7053/tcp
CONTAINER ID : d11bdaf8e7a0 | Name: peer0.ORG1.ac.ae | Image:  hyperledger/fabric-peer:1.4 |  Ports: 0.0.0.0:17051->7051/tcp, 0.0.0.0:17053->7053/tcp
CONTAINER ID : b521f48a3cf4 | Name: couchdb1 | Image:  hyperledger/fabric-couchdb:0.4.15 |  Ports: 4369/tcp, 9100/tcp, 0.0.0.0:5985->5984/tcp
CONTAINER ID : 14436927aff7 | Name: ca.ORG1.ac.ae | Image:  hyperledger/fabric-ca:1.4 |  Ports: 0.0.0.0:7054->7054/tcp

CONTAINER ID : 107466b8b1cd | Name: ca.ORG2.ac.ae | Image:  hyperledger/fabric-ca:1.4 |  Ports: 0.0.0.0:7055->7054/tcp
CONTAINER ID : 882aa0101af2 | Name: orderer1.o1.ac.ae | Image:  hyperledger/fabric-orderer:1.4 |  Ports: 0.0.0.0:7050->7050/tcp

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

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

Thanks for the answer of https://stackoverflow.com/a/65513726/889126, it gave me an idea to make a complete bash script as it is

export api_image_id=$(docker inspect --format="{{.Id}}" <image-name> | sed '/^[[:space:]]*$/d')

sudo docker exec -i -t ${api_image_id} /bin/bash

I need a specific container and make a script to extract some info from it in a quick sight.

Hope this would help others.

You could use the following command to print the container id:

docker container ls  | grep 'container-name' | awk '{print $1}'

As a bonus point, if you want to login to the container with a container name:

docker exec -it $(docker container ls  | grep 'container-name' | awk '{print $1}') /bin/bash
