In our earlier articles, we saw how to install Docker engine on CentOS 7 / RHEL 7 / Ubuntu 16.04, and  Debian 9. As part of that, we run containers by pulling images from Docker Hub.

Remove Docker Images:

To remove Docker images, we can use docker rmi command along with image ID or repository name.

docker rmi <IMAGE ID>


docker rmi <REPOSITORY>

List out the available images on your system using the following command.

docker images


REPOSITORY            TAG                 IMAGE ID            CREATED             SIZE      latest              ccc7a11d65b1        3 days ago          120.1 MB   latest              c4260b289fc7        10 days ago         405.8 MB      latest              328edcd84f1b        10 days ago         192.5 MB       latest              c73c7527c03a        2 weeks ago         412.3 MB      latest              49236bc2f0da        3 weeks ago         230.6 MB

Choose the Docker image you want to remove and run the following command. In my case,

docker rmi c4260b289fc7


docker rmi

Remove All Docker Images:

Some times, you may want to clean whole Docker images in a single go. Run the following command to remove all Docker Images.

docker rmi $(docker images -q)

Remove Docker Containers:

To remove Docker containers, you can use docker rm command along with container id.

docker rm <CONTAINER ID>

List all of your Docker containers using docker ps -a command.

docker ps -a


CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS               NAMES
8c6be9547a71        fedora              "/bin/bash"         About a minute ago   Up About a minute                       docker-fedora
a4d876cc42d5        ubuntu              "/bin/bash"         2 minutes ago        Up 2 minutes                            docker-ubuntu
79dc279d7674        centos              "/bin/bash"         2 minutes ago        Up 2 minutes                            docker-centos

Note down the container ID of the one you want to remove. You need to stop the container first using docker stop command before removing the container. In my case,

docker stop 8c6be9547a71

Then, remove Docker container using docker rm command.

docker rm 8c6be9547a71

Note: You can also force the removal of Docker container while it is running using docker rm <CONTAINER ID> -f.

Remove All Docker Containers:

To remove all of your Docker containers in one go, run the following command.

docker rm -f $(docker ps -a -q)

That’s All.
