Docker error cannot delete docker container, conflict: unable to remove repository reference
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 78479ffeba5c ubuntu "/bin/bash" 42 hours ago Exited (0) 42 hours ago sharp_wescoff 81 B (virtual 187.7 MB) 0bd2b54678c7 training/webapp "python app.py" 5 days ago Exited (0) 5 days ago backstabbing_ritchie 0 B (virtual 323.7 MB) 0adbc74a3803 training/webapp "python app.py" 5 days ago Exited (143) 5 days ago drunk_feynman 0 B (virtual 323.7 MB)
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?
First, remove the container names
$ sudo docker rm backstabbing_ritchie
$ sudo docker rm backstabbing_ritchie backstabbing_ritchie
delete the second part, which is listed on the container to be deleted
$ sudo docker rm drunk_feynman drunk_feynman
Second, remove the container
$ sudo docker rmi training/webapp
$ sudo docker rmi training/webapp Untagged: training/webapp:latest Deleted: 54bb4e8718e8600d78a5d7c62208c2f13c8caf0e4fe73d2bc0e474e93659c0b5 Deleted: f74dd040041eb4c032d3025fe38ea85de8075992bdce6789b694a44b20feb8de Deleted: 7cbae69141977b99c44dc6957b032ad50c1379124d62b7d7d05ab7329b42348e Deleted: abb991a4ed5e4cde2d9964aec4cccbe0015ba9cc9838b696e7a32e1ddf4a49bd Deleted: 1952e3bf3d7e8e6a9b1e23bd4142e3c42ff7f4b7925122189704323593fd54ac Deleted: f95ebd363bf27a7546deced7a41a4099334e37a3d2901fa3817e62bb1ade183f Deleted: 20dd0c75901396d41a7b64d551ff04952084cc3947e66c67bae35759c80da338 Deleted: 2505b734adda3720799dde5004302f5edb3f2a2ff71438f6488b530b728ba666 Deleted: 2ee0b8f351f753f78f1178000ae37616eb5bf241d4ef041b612d58e1fd2aefdc Deleted: 2ce633e3e9c9bd9e8fe7ade5984d7656ec3fc3994f05a97d5490190ef95bce8d Deleted: 98b15185dba7f85308eb0e21196956bba653cf142b36dc08059b3468a01bf35d Deleted: 515565c29c940355ec886c992231c6019a6cffa17ff1d2abdfc844867c9080c5 Deleted: 2880a3395eded9b748c94d27767e1e202f8d7cb06f1e40e18d1b1c77687aef77

There is a difference between docker images and docker containers. Check this SO Question.
In short, a container is a running instance of an image. which is why you cannot delete an image if there is a running container from that image. You just need to delete the container first.
Docker ps -a # Lists containers (and tells you which images they are spun from) Docker images # Lists images Docker rm <container_id> # Removes a container Docker rmi <image_id> # Removes an image # Will fail if there is a running instance of that image i.e. container Docker rmi -f <image_id> # Forces removal of image even if it is referenced in multiple repositories, # i.e. same image id given multiple names/tags # Will still fail if there is a docker container referencing image
Update for Docker 1.13+ [Since Jan 2017]
In Docker 1.13, we regrouped every command to sit under the logical object it’s interacting with
Basically, above commands could also be rewritten, more clearly, as:
Docker container ls Docker image ls Docker container rm <container_id> Docker image rm <image_id>
you can use -f option to force delete the containers .
sudo docker rmi -f training/webapp
You may stop the containers using sudo docker stop training/webapp before deleting
If you want to cleanup docker images and containers
CAUTION: this will flush everything
stop all containers
docker stop $(docker ps -a -q)
remove all containers
docker rm $(docker ps -a -q)
remove all images
docker rmi -f $(docker images -a -q)
If you have multiples docker containers launched, use this
$ docker rm $(docker ps -aq)
It will remove all the current dockers listed in the "ps -aq" command.

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>.
