nginx upstream srv module

a nginx module, support dns srv base on tengine ngx_http_upstream_dynamic_module

How to support

nginx ngx_resolve_name function query SRV record, if ctx->service not empty.
so ngx_http_upstream_dynamic_module set ctx->service is your domain suffix, ctx->name is servicename.

TODO

ctx->service read from upstream config

config

like that

    upstream backend {
        dynamic_resolve fallback=stale fail_timeout=30s;
        server test1.kns.local;
    }

expect config

    upstream backend {
        dynamic_resolve fallback=stale fail_timeout=30s;
        server kns.local test1;
    }

DNS SRV query: test1.kns.local

Hard code current

https://github.com/tiny1990/nginx-srv/blob/master/ngx_http_upstream_dynamic_module.c#L512
server name needs endWith kns.local

What's the next

ctx->name and ctx->serice configable
