Jenkins master - 从这台机器上，我无法访问互联网/外部世界。

Jenkins 从属服务器，运行 docker 容器（用于从属服务器），可以访问外部世界/互联网。

我安装了 PagerDuty 插件并在作业中正确配置了它，以便在每次失败以及状态恢复正常时发送通知。

当我运行这项工作时，我收到以下错误消息com.mashape.unirest.http.exceptions.UnirestException: org.apache.http.conn.ConnectTimeoutException: Connect to events.pagerduty.com:443 [events.pagerduty.com/54.244.255.45, events.pagerduty.com/54.241.36.66, events.pagerduty.com/104.45.235.10] failed: connect timed out。

我首先登录从机并尝试 ping events.pagerduty.com 服务器旁边的 IP（如上所列）并且 ping 工作正常。在端口 443 (ssh) 上执行 telnet 也提供了有效的输出。

由于从属服务器实际上是 docker 容器，我进入其中一个容器从属服务器并做了同样的事情（对于这些 events.pagerduty.com IP、nslookup 和 nc / ncat 等，在 443 上进行 ping、telnet 和输出看起来不错）。

在这里，我在 docker slave 容器的主机内，即我跑了docker exec -it shenazi_ninza bash，现在我在容器的主机/IP 内：

Jenkins 作业配置中的 PagerDuty 集成在POST Built Actionsarea 下可用。

我的问题是，整个工作不是在从服务器上运行吗（又名容器的从服务器，我可以从那里访问外部世界并且我能够连接到 events.pagerduty.com 服务器）？

似乎 JenkinsPOST Build Data在我无法访问 events.pagerduty.com（ping/telnet 等）的主 Jenkins 实例上运行该部分下的任何内容？由于我们不希望 Jenkins master 具有外部世界访问权限，如何解决此问题，以便在该作业的构建失败时收到警报？

因此，不是打开所有访问，而是添加了使用给定网关/路由的路由来仅访问 events.pagerduty.com 服务器

/sbin/route add -net 50.0.0.0/8 x.x.x.x dev eth0
/sbin/route add default gw x.y.z.someIP
/sbin/route add -net 50.0.0.0 netmask 255.0.0.0 gw x.y.z.ip

现在从詹金斯大师那里，我只能看到/访问 events.pagerduty.com 服务器/它的 IP。

xyzip 是你必须放的东西。
