I’m trying to set upstream names by variables, but nginx recognizes
variables as hostnames, not upstream names.
For example:
map $cookie_backend $proxy_host {
default ‘backend1’;
‘1’ ‘backend2’;
}
… … …
upstream backend1 {
server backend123:8080;
server backend124:8080;
}
… … …
upstream backend2 {
server backend223:8080;
server backend224:8080;
}
… … …
location / {
proxy_pass http://$proxy_host;
}
nginx returns error message:
2014/04/09 14:19:51 [error] 1085#0: *1128620 backend1 could not be
resolved
(3: Host not found) while sending to client, client: 192.168.1.145,
server:
localhost, request: “GET / HTTP/1.1”, host: “localhost”

Hello!
You need to use resolver directive in Nginx.
Also you need to set DNS entries for your backend hostname.

My bad, in one location I forgot to remove port, that is why nginx tried
to
resolve upstream as hostname.
