   https://github.com/openspug/spug
   sudo docker pull openspug/spug
   sudo docker run -d -p 80:80 openspug/spug
   if port 80 already in use, you can find the process by:
   sudo lsof -i:80
   in our case it’s apache, stop it with:
   sudo systemctl stop apache2

sudo docker ps to get running container details:

(base) ubuntu@ubunu2004:/$ sudo docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                NAMES

initial and restart the spug:
export CONTAINER_ID=c493cbf6aceb
sudo docker exec $CONTAINER_ID init_spug admin spug.dev
sudo docker restart $CONTAINER_ID
