Non-availability outside docker container

[Ilya Goss]

Unlike nodejs process, PHP React HTTP listens to something that doesn't allow localhost to be seen outside the container.
What to do? See netstat comparison of ReactPHP and Nodejs

[Christian Lück]

This is actually a Socket feature and it works as expected and documented :-)

If you want to listen on all or some public interfaces, you have to specify which address your server socket is listening on like this:

$server = new Server('[::]:80', $loop);

See https://github.com/reactphp/socket#server for more details.

I hope this helps 👍
