I have an application with two github repos one for react and one for rails app. Requirement is all the routes should go to Rails server except routes starting with /catalog should go to to React app. Rails app server will communicate with React Server internally. SSL is configured on Nginx level.
I have created 3 different apps in heroku :
My nginx server config looks like :
upstream rails {
server $HEROKU_APP_rails_URL;
}
upstream react {
server $HEROKU_APP_react_URL;
}
server {
listen $PORT;
server_name *.xyz.com;
# large_client_header_buffers 4 32k;
location / {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://rails;
}
location /catalog {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://react;
}
}
with above config I am getting HTTP 400 error on Nginx and it is not able to redirect the request. Please let me know what am i doing wrong.
Finally managed to solve this issue.. My nginx config looks like
upstream upstream_app_a {
server app_a.herokuapp.com:443;
}
upstream upstream_app_b {
server app_b.herokuapp.com:443;
}
server {
listen $PORT;
location / {
set $upstream upstream_app_a;
proxy_pass https://$upstream;
proxy_ssl_name app_a.herokuapp.com;
proxy_set_header x-forwarded-host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host app_a.herokuapp.com;
}
location /static {
set $upstream upstream_app_b;
proxy_pass https://$upstream/static;
proxy_set_header Host app_b.herokuapp.com;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
location /product_catalog {
set $upstream upstream_app_b;
proxy_pass https://$upstream;
proxy_ssl_name app_b.herokuapp.com;
proxy_set_header x-forwarded-host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host app_b.herokuapp.com;
}
}
Please make sure you set correct value for header
proxy_set_header Host app_a.herokuapp.com
