Docker
``` $ docker run -p 127.0.0.1:80:8080/tcp ubuntu bash ``` This binds port 8080 of the container to TCP port 80 on 127.0.0.1 of the host machine. You can also specify udp and sctp ports. ``` $ docker run --expose 80 ubuntu bash ``` This exposes port 80 of the container without publishing the port to the host system’s interfaces.
