I have this situation where a have lots of API´s running on different machines on different ports using Tomcat. I can create the upstream with those IP addresses but how to add the other part of the URL to the upstream when setting the proxy_pass?
The upstream:
upstream login_api_stream {
least_conn;
server 10.2.54.8:8185;
server 10.2.54.8:8285;
server 10.2.54.8:8385;
server 10.2.54.9:8085 backup;
}
Then I create the location inside http:
location /login-api/ {
add_header X-Real-IP $remote_addr;
add_header X-Forwarded-For $proxy_add_x_forwarded_for;
add_header X-Forwarded-Proto $http_x_forwarded_proto;
# I have to add "login-api/auth" on the upstream
proxy_pass http://login_api_stream/login-api/auth;
}
As you can see I must add this "login-api/auth" because the real URL address on the redirected address is: http://10.2.54.8:8185/login-api/auth
How can I do that?
After some digging I ended up with this solution:
The upstream (important to notice, you cannot use this sign _ in the name of the upstream):
upstream newlogin {
least_conn;
server 10.2.54.8:8085;
server 10.2.54.8:8285;
server 10.2.54.8:8185;
server 10.2.54.9:8085 backup;
}
The location:
location ~ ^/login-api/auth/ {
add_header Host $host;
add_header X-Real-IP $remote_addr;
add_header X-Forwarded-For $proxy_add_x_forwarded_for;
add_header X-Forwarded-Proto $http_x_forwarded_proto;
proxy_pass http://newlogin$uri$is_args$args;
}
And then in browser I call:
http://MyNginxDomain/login-api/auth/
