Docker-compose：使用gelf驱动程序无法解析链接容器的主机

Question

我正在尝试将我的容器生成的日志重定向到另一个持有ELK的容器，但是我收到了这个错误：

ERROR: for uid-manager  Failed to initialize logging driver: gelf: cannot connect to GELF endpoint: elk_stack:12201 dial udp: lookup elk_stack: no such host

这是我的配置：

version: '2'
services:
   elk_stack:
     image: sebp/elk
     container_name: elk_stack
     ports:
      - "5601:5601"
      - "9200:9200"
      - "12201:12201/udp"
     expose:
      - "5601"
      - "9200"
      - "12201/udp"
   uid-manager:
     image: uid-manager-server:latest
     container_name: uid-manager
     ports:
      - "15100:15100"
      - "9111:9111"
     expose:
      - "15100"
      - "9111"
     logging:
      driver: gelf
      options:
       gelf-address: "udp://elk_stack:12201"
     environment:
      - [...]
     links:
      - elk_stack

你能告诉我我做错了什么吗？谢谢！
