I cannot use a variable for fastcgi_pass directive as below

fastcgi_pass $image:9000;

I get the following error.

 2020/07/07 01:39:08 [error] 27#27: *1 no resolver defined to resolve php, client: 192.168.48.1, server: , request: "GET /info.temp.php HTTP/1.1", host: "127.0.0.3"

The $image variable has a valid value and if I hard code the value instead of the variable it will start to work.

Any workaround or fix please?

  • Is this happens inside a docker container? Jul 7, 2020 at 1:51
  • @IvanShatsky Yes. it does Jul 7, 2020 at 2:02
  • You probably need to use resolver 127.0.0.11; inside the docker, see this answer. Jul 7, 2020 at 2:06
  • @IvanShatsky Many Thanks. It fixed it. You are the best! Jul 7, 2020 at 2:15
  • @IvanShatsky It's so strange that a variable behaves differently than it's the same value Jul 7, 2020 at 2:20

The documentation states:

Parameter value can contain variables. In this case, if an address is specified as a domain name, the name is searched among the described server groups, and, if not found, is determined using a resolver.

You need to have a resolver configured because the value didn't match any of your defined upstream servers.
