我试过了

  • dns: dns-server
  • dns: 127.0.0.1
  • dns: 192.168.2.170
  • dns: 172.21.0.2（dns 服务器容器 IP）

其次是sudo docker compose down && sudo docker compose up -d

但它从来没有解决jenkins.webdev或gitea.webdev像192.168.2.170在dns服务器设置

dns 服务器运行正常。

在此处输入图片描述 在此处输入图片描述 在此处输入图片描述

这一切都在 Ubuntu VM 内部，我的 Windows 主机以 192.168.2.170 作为主 DNS，并且可以很好地解析 jenkins.webdev 和 gitea.webdev。

编辑：更新了我的 docker-compose.yml 文件以反映当前状态，我尝试停止所有容器，然后：

  • 在 dns-server 撰写文件中创建网络
networks:
  dns-network:
    name: dns-network
    driver: bridge
  • 将该网络添加到 jenkins 和 gitea 作曲家文件中
networks:
  gitea-network:
    name: dns-network
    external: true

services:
  server:
     networks:
      - gitea-network
  dns: dns-server

仍然不起作用，在 gitea 容器中我可以 ping dns-server，并且显示的 ip 是正确的，但如果我 ping webdev、gitea.webdev 或 jenkins.webdev，我会得到ping: bad address

我可以 pingjenkins或gitea，并且我可以看到本地 IP，但jenkins.webdev和gitea.webdev指向我192.168.2.170在 dns-server 中定义的主机 IP 是bad address，如果我尝试使用jenkins或 ，gitea我会得到Delivery: Post "https://jenkins/gitea-webhook/post": dial tcp 172.20.0.5:443: connect: connection refused
