 Got the container running? Good. Next step... 
 Test it 
 sudo docker logs <container_name> 
 You can also use  
 sudo docker logs minecraft-minecraft-1 | grep "logged in with entity id" 
 Check for errors and see what it says.  
 
 Using hose / .service to open and close ports AND start and stock docker. 
 This is going to allow you to open up the ports to your sever using UFW only when you start it up. Then it will close them, when you stop the service.  
 Go to:  
 sudo vim /etc/systemd/system/minecraft.service 
 You may not have that file yet. if not, just create it new and paste in the below.  
 You will need to change these directories to match where your data is stored.  WorkingDirectory=/opt/minecraft ExecStart=/usr/bin/docker compose up -d ExecStop=/usr/bin/docker compose down
