NGINX Format for AWS EB Web Sockets - amazon-web-services

Question

Does anyone have a formatted nginx.config file for upgrading AWS EB to allow for web sockets? It would be great to see your example nginx.config files for this. I found I need to setup the nginx.config from this link.
Here's the one I thought was going to work before I tried other things but it and various similar versions I put through a YAML validator gave deployment errors:
files:
/etc/nginx/conf.d/proxy.conf:
content: |
http {
client_max_body_size 50M;
}
client_max_body_size 50M;
upstream nodejs {
server 127.0.0.1:8081;
keepalive 256;
}
server {
listen 8080;
if ($time_iso8601 ~ "^(\d{4})-(\d{2})-(\d{2})T(\d{2})") {
set $year $1;
set $month $2;
set $day $3;
set $hour $4;
}
access_log /var/log/nginx/healthd/application.log.$year-$month-$day-$hour healthd;
access_log /var/log/nginx/access.log main;
location / {
proxy_pass http://nodejs;
proxy_set_header Connection "";
proxy_http_version 1.1;
proxy_set_header Host $host;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
gzip on;

I've tried about a dozen formats I've found across the internet to no avail including from the following links:
