GitHub webhook 无法在 VPN 内连接到 Jenkins？

Question

我正在使用 Jenkins 和 GitHub Enterprise 设置持续集成。

\n

到目前为止，我已经能够轻松创建 Jenkins 项目并定期运行作业。

\n

\n
• Jenkins 使用 SSH 公钥/私钥来验证和克隆 GitHub 存储库。
\n
• Jenkins 在我公司 VPN 网络内的 Linux 服务器上运行。
\n

\n

我的下一步是配置 Jenkins/GitHub，以便每个git pushGitHub 都会触发 Jenkins 构建作业。我已在 GitHub 上设置了提交后 Webhook，并GitHub hook trigger for GITScm polling在我的 Jenkins 项目中启用了该复选框。

\n

但是，GitHub 无法连接到 Jenkins。

\n

这是日志：

可能是什么问题呢？

Answer 1

那么问题正是因为github无法访问你的内部网络。

Jenkins 社区博客中有一篇文章，作者建议使用smee（在 ISC 许可证下发布）进行 webhooks 转发。
