docker - Drone CI runner 找不到 gitea 服务器

Question

我正在尝试使用无人机运行 gitea 服务器。它们目前都托管在同一台 ubuntu 机器上，并且 docker 容器是通过 docker-compose.yml 文件设置的。

启动所有服务时，我在drone runner 服务的日志中收到以下错误：

time="2020-08-12T19:10:42Z" level=error msg="cannot ping the remote server" error="Post http://drone:80/rpc/v2/ping: dial tcp: lookup drone on 127.0.0.11:53: no such host"

http://gitea 和 http://drone 都指向 localhost（通过 /etc/hosts）。遗憾的是，我不明白无人机跑步者如何或为什么找不到服务器。在我所有的 4 个容器上调用“docker container inspect”表明它们都连接到同一个网络（drone_and_gitea_giteanet）。这也是我在 DRONE_RUNNER_NETWORKS 环境变量中设置的网络。

这是我的 docker-compose.yml 文件的外观：

version: "3.8"

如果有人可以看看这个问题并帮助我，那将对我有很大帮助！:)
