Docker error response from daemon: "Conflict ... already in use by container"
It looks like a container with the name qgis-desktop-2-4 already exists in the system. You can check the output of the below command to confirm if it indeed exists:
$ docker ps -aThe last column in the above command's output is for names.
If the container exists, remove it using:
$ docker rm qgis-desktop-2-4Or forcefully using,
$ docker rm -f qgis-desktop-2-4And then try creating a new container.
I got this error quite a lot, so now I do a batch removal of all unused containers at once:
docker container prune add -f to force removal without prompt.
To list all unused containers (without removal):
docker container ls -a --filter status=exited --filter status=created See here more examples how to prune other objects (networks, volumes, etc.).
