Docker error response from daemon: Conflict. already in use by container

Question

I use docker to start Quantum GIS, following the instructions I found here: https://registry.hub.docker.com/u/kartoza/qgis-desktop/

Everything worked fine until the last week when I started receiving this error message: Error response from daemon: Conflict. The name "qgis-desktop-2-4" is already in use by container 235566ae17b8. You have to delete (or rename) that container to be able to reuse that name. Error response from daemon: Conflict. The name "qgis-desktop-2-4" is already in use by container 235566ae17b8.

I'm not quite sure what this means, despite looking for clues in this forum. I have not changed anything before and successfully launched the container with this command:

 sudo docker run --rm --name="qgis-desktop-2-4" -i -t -v ${HOME}:/home/${USER} -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=unix$DISPLAY kartoza/qgis-desktop:latest 

Any ideas how I can fix this?

thank

It looks like a container named qgis-desktop-2-4 already exists on the system. You can check the output of the command below to confirm whether it really exists:

 $ docker ps -a 

The last column in the command output file for names.

If the container exists, delete it using:

 $ docker rm qgis-desktop-2-4 

or forced

 $ docker rm -f qgis-desktop-2-4 

And then try creating a new container. Hope this helps!
