GELF logging driver with Windows Containers
The supported log drivers section does list GELF (Graylog Extended Log Format), but by default on docker for Linux (so within a Linux VM on other platforms)
The official GELF documention does recommend in its installation page
Some modern Linux distribution (Debian Linux, Ubuntu Linux, or CentOS recommended)
So a Windows server 2016 might not include a Graylog server in its Docker.
