Docker/K8 : OpenSSL SSL_connect: SSL_ERROR_SYSCALL

编程问答 2022-05-11

问题描述

在端点上运行 k8 cronjob。测试在本地就像一个魅力，即使当我在入口点的末尾 sleep infinity 然后在容器内卷曲时也是如此。但是，一旦 cron 启动，我就会收到一些奇怪的错误：

[ec2-user@ip-10-122-8-121 device-purge]$ kubectl logs appgate-device-cron-job-1618411080-29lgt -n device-purge

请帮忙！我的想法不多了....

解决方法

由于在 AWS 云帐户上设置了 IP 白名单的某些防火墙，我的帖子的问题出在服务器本身上。在帐户的安全团队解决了该问题后，我能够通过阻止程序。

看看 https://docs.thousandeyes.com/product-documentation/tests/http-server-test-fails-with-ssl-error-openssl-ssl_connect-ssl_error_syscall 听起来确实是您遇到的问题。
