Docker error cannot delete docker container, confl

Question

I want to remove the container at Docker, but an error occurs when you want to delete

My next step before removing the container, see the list of existing container

sts@Yudi:~/docker$ sudo docker ps -as

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                    PORTS               NAMES                  SIZE

one I want to delete the list, namely "training / webapp" but an error that occurred

sts@Yudi:~/docker$ sudo docker rmi training/webapp
Error response from daemon: conflict: unable to remove repository reference "training/webapp" (must force) - container 0bd2b54678c7 is using its referenced image 54bb4e8718e8
Error: failed to remove images: [training/webapp]

Whether the container is running in the images?

Please help

Answer 1

Noticed this is a 2-years old question, but still want to share my workaround for this particular question:

Firstly, run docker container ls -a to list all the containers you have and pinpoint the want you want to delete.

Secondly, delete the one with command docker container rm <CONTAINER ID> (If the container is currently running, you should stop it first, run docker container stop <CONTAINER ID> to gracefully stop the specified container, if it does not stop it for whatever the reason is, alternatively you can run docker container kill <CONTAINER ID> to force shutdown of the specified container).

Thirdly, remove the container by running docker container rm <CONTAINER ID>.

Lastly you can run docker image ls -a to view all the images and delete the one you want to by running docker image rm <hash>.

Answer 2

Remove just the containers associated with a specific image

docker ps -a | grep training/webapp | cut -d ' ' -f 1 | xargs docker rm

• ps -a: list all containers
• grep training/webapp : filter out everything but the containers started from the training/webapp image
• cut -d ' ' -f 1: list only the container ids (first field when delimited by space)
• xargs docker rm : send the container id list output to the docker rm command to remove the container
