What is the easiest way to access a host from a docker container?

Question

Docker

A test piece of hardware with nginx, mariadb, php5.6-fpm I wouldn’t want to blow up anything here, put a php: 7.1-cli docker container nearby, everything seems to be alive, but mariadb has to knock on the public IP (I had to open a port outside), maybe there is there an easier way to communicate with the DB on the host? Or just put the mariaDB container next to it and through compose?

Answer 1

Php different versions get along fine on the same host. In general, the host IP must be the gateway IP. Something like 10.0.3.1
