Question

我正在运行多个网站，并在一个使用traefik作为反向代理的系统上使用docker-compose进行监视。每个网站都可以从外部和主机本身访问，但是Prometheus本身无法从同一主机上的网站中获取指标。

因此从我的本地计算机或主机上的命令行进行的telnet连接返回200：

$ telnet api.dev.inowas.com 80
Trying 142.93.175.226...
Connected to api.dev.inowas.com.
...

prometheus容器中的同一命令未连接

$ /prometheus $ telnet api.dev.inowas.com 80
...

与curl，nc等其他工具相同的结果。

我正在为此设置运行三个docker-compose配置。

我希望检索调用该网址的指标：

https://api.dev.inowas.com/metrics来自prometheus容器，因为我可以从任何其他主机执行此操作。

无法从Prometheus容器中指向同一host-ip的网址
