 - `--publish 8080:8080` This means that port 8080 of the container should get published on the host using port 8080. This port is used for the AIO interface and uses a self-signed certificate by default. You can also use a different host port if port 8080 is already used on your host, for example `--publish 8081:8080` (only the first port can be changed for the host, the second port is for the container and must remain at 8080).

 - `--env APACHE_IP_BINDING=0.0.0.0` This can be modified to allow access to the published port on the host only from certain ip-addresses. [See this documentation](#3-limit-the-access-to-the-apache-container)
