consul 用如下命令启动：
sudo docker run -d --name=consul -p 8500:8500 -p 8600:8600/udp -v /home/alex/code/consul-data:/consul/data consul:1.15.4

nginx.conf 配置如下：
stream {
resolver 192.168.1.125:8600 ipv6=off valid=30s;

upstream tcp_servers {  
    server my-service.service.consul:6789;  
}  

server {  
    listen 12345;  
    proxy_pass tcp_servers;  
    proxy_connect_timeout 1s;  
}

}

后端的 TCP 服务器已经成功注册到 consul ，执行 dig @192.168.1.125 -p 8600 my-service.service.consul 是可以正确解析域名的，但是配置在 nginx 里面，就提示： nginx: [emerg] host not found in upstream "my-service.service.consul:6789" in /etc/nginx/nginx.conf:73
nginx: configuration file /etc/nginx/nginx.conf test failed

搞了一上午，怎么改配置都不行

nginx 没有运行在 docker 里面，是系统命令运行。
nginx.conf 配置如下：

load_module /usr/lib/nginx/modules/ngx_stream_module.so;
worker_processes auto;
worker_rlimit_nofile 30000;

events {
worker_connections 10240;
}

http {
client_max_body_size 100m;
resolver 8.8.8.8;

upstream specification_server {
server 127.0.0.1:6088;
server 127.0.0.1:6089;
}

upstream http_server {
server 172.16.15.9:8090;
server 172.16.15.9:8091;
}

server {
listen 80;

location /get {
proxy_pass http://http_server/get;
}

access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;

location / {
root /usr/share/nginx/html;
}
location = /maintenance.html {
root /usr/share/nginx/html;
internal;
}

# 其他配置项...
}
}

stream {
resolver 192.168.1.125:8600 valid=30s;

upstream tcp_servers {
server my-service.service.consul:6789;
#server 192.168.1.126:6789;
}

server {
listen 12345;
proxy_pass tcp_servers;
proxy_connect_timeout 1s;
}
}

如果直接用 nginx.conf 只用 server 192.168.1.126:6789;是可以的，但是就失去意义了，向让 nginx 动态发现后端的服务器。

Nginx

Consul

resolver
