Update README.md - fix wrong docker-compose configuration
The documentation for the omnibus configuration of the docker-compose.yml
is wrong/ not precisely.
When you change the external ports for http and ssh you do not need to change the internal ports in the container as well. The internal ports stay at 80
and 22
unless you configure it with e.g. nginx['listen_port'] = 80
and/or unicorn['port'] = 2224
This patch fixes this flaw to have an "out-of-the-box" running example with custom external ports
