How to apply a dns server running in docker-compsoe to another service running in the same docker-compsoe?

[aa51513]

For business needs, I used docker-compose to orchestrate a dns server, and the service name in docker-compose is my_dns_server.

I would like to use the above dns server for domain name resolution in the container where my business is running.

My config file is as follows: version: '3.8' services: my_dns_server: image: coredns/coredns container_name: coredns restart: always volumes: - /etc/coredns/Corefile:/etc/coredns/Corefile:ro my_business_service: image: my/business:latest container_name: my_business_service restart: always volumes: - /etc/my/config.yml:/etc/my/config.yml:ro depends_on: - my_dns_server dns: my_dns_server

In fact, the above configuration does not work at all. In my business container, I cannot perform any external network DNS resolution. I want to know, is there something wrong with my configuration, or docker-compose itself does not support this configuration, and how should I achieve the above requirements?
