GitLab Runner：无法注册运行器。您可能遇到网络问题

Question

我正在尝试创建一个 kubernetes gitlab 运行程序，并且遇到了Failed to register the runner. You may be having network problems.我知道gitlab.com可以从我的主机访问的非常普遍的错误，但我需要更多信息来调试此问题的根本原因。

请注意，该错误确实会持续 30 次尝试，每次尝试与以下情况相同：

防火墙阻止了从主机到 GitLab 的 Kubernetes 流量。一旦来自的流量gitlab.com被列入白名单，运行器就会被创建。
