Yep it's a good call out. Another good habit that you allude to is to publish ports to both an interface and port on the host system, not just a port (which assumes all interfaces, including external ones like wifi). The syntax slightly changes so you do command line option '-p "127.0.0.1:5000:5000"' which means on my host machine's localhost only (127.0.0.1) listen on port 5000 and forward it to port 5000 in the container. That way only a process running on my local machine can connect to my container and not someone else on the network if I forgot to turn on a firewall. |
