Docker injects environment variables with ip addresses, as well as setting the host name. Hence it's very easy to use the environment variables and not worry about hostnames :-)

    backend beChalet
            option httpchk GET /
            server chalet ${CHALET_PORT_80_TCP_ADDR}:${CHALET_PORT_80_TCP_PORT} maxconn 200 check
