# Not exposing ports, as it might be more efficient to run this on host network because of performance gain.
# | Host mode networking can be useful to optimize performance, and in situations where a container needs
# | to handle a large range of ports, as it does not require network address translation (NAT), and no
# | “userland-proxy” is created for each port.
