HOW TO remove docker dangling and unused images

Let us extend the concept of Spring Cleaning to our computers, virtual machines and servers where we are using Docker.

I was starting writing some PowerShell script from the list of the docker images

PS C:\> docker images

and thinking which filters to apply when I thought that maybe docker contains already a command that does some good cleanup.

Here the result of my research, we can use docker image prune, in my case I added also the parameters -a to remove all unused images (all images without at least one container associated to them) and -f that stands for Force to do not prompt for confirmation:

PS C:\> docker image prune -a -f

Note: every docker image related to Microsoft Dynamics NAV or Microsoft Dynamics 365 Business Central takes usually 10-20 GB of space.

If you use navcontainerhelper for the creation of the Docker containers I suggest you to have a look also of the content of the folder under the following path:


You could find old database backup or source file objects downloaded that could be deleted as well.

Docker Microsoft PowerShell

docker : Error response from daemon: removal of container ### is already in progress

You run one of the following PowerShell commands to remove a container

Remove-NavContainer ###


docker rm ###

but you receive the following error message:

docker : Error response from daemon: removal of container ### is already in progress

with the result that you are unable to stop, kill or remove the Docker container. Even a restart does not fix this issue.

Solution 1:

  1. Run the PowerShell command net stop docker to stop docker-engine (Note all containers will stop)
  2. Delete the folder in C:\Programdata\docker\containers whose name starts with the ID from the error message (###)
  3. Run the PowerShell command net start docker to start docker-engine

Solution 2:

Restart the machine will restart docker-engine if it the service is set up to start Automatically.
