Non HTTP stuff on Elastic Beanstalk

No, aws doesn't expose port when running docker. But it uses port information from the container to create an upstream on nginx config.

/etc/nginx/conf.d/elasticbeanstalk-nginx-docker-upstream.conf

upstream docker {
	server 172.17.0.33:24224;
	keepalive 256;
}

Then another file to do reverse-proxy

/etc/nginx/sites-enabled/elasticbeanstalk-nginx-docker-proxy.conf

map $http_upgrade $connection_upgrade {
	default		"upgrade";
	""			"";
}

server {
	listen 24224;

	location / {
		proxy_pass			http://docker;
		proxy_http_version	1.1;

		proxy_set_header	Connection			$connection_upgrade;
		proxy_set_header	Upgrade				$http_upgrade;
		proxy_set_header	Host				$host;
		proxy_set_header	X-Real-IP			$remote_addr;
		proxy_set_header	X-Forwarded-For		$proxy_add_x_forwarded_for;
	}
}

I think we need to remove http from that proxy_pass line.

I'll post an update when it works.

PS:
Let me know if trying to run fluentd on EB is not a futile effort.

Update:
I managed to make it works!
