За да изпълните примера за чат на websocket при внедряване на Elastic Beanstalk с един екземпляр в AWS, ще трябва да добавите следната конфигурация на Nginx прокси (Забележка:заменете "env1.t3tiiauce6.us-west-2.elasticbeanstalk.com" с името на вашия сайт):
.ebextensions/nginx_proxy.config
files:
"/etc/nginx/conf.d/websockets.conf" :
content: |
upstream backend {
server unix:///var/run/puma/my_app.sock;
}
server {
listen 80;
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
server_name env1.t3tiiauce6.us-west-2.elasticbeanstalk.com
