[deploy] nginx: no resolver defined to resolve node #5

Open oonexdl opened 6 years ago

nginx -v

nginx version: nginx/1.13.9

原因:

nginx proxy_pass 指令后的参数如果含有变量，则会使用内建的 resolver, 此时必须显示指定 resolver 地址 http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_pass

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.

临时解决方法:

specify resolver address in location block, http://nginx.org/en/docs/http/ngx_http_core_module.html#resolver

location = /index.js {
    proxy_http_version 1.1;
    resolver 127.0.0.11; # https://docs.docker.com/v17.09/engine/userguide/networking/configure-dns/
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_set_header X-NginX-Proxy true;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_pass http://node:$node_port$request_uri;
    proxy_redirect off;
}

install dnsmasq，add resolver address to 127.0.0.1
