docker is easily broken, e.g. its process management becomes easily out of sync.
I.e create container, kill process 1, then exit.

CID=$(docker run -it -d ubuntu:latest bash);
docker exec -i -t $CID kill 1;
docker ps
docker rm -f $CID;

Error response from daemon: Could not kill running container, cannot remove - no such process
FATA[0000] Error: failed to remove one or more containers
