Question

我在mesos v1.0.5 / go 1.5上使用kubernetes

我遇到kubectl命令返回错误的问题

我按照文档中的示例启动了busybox：
http://kubernetes.io/v1.0/docs/getting-started-guides/mesos.html

'kubectl exec busybox - nslookup kubernetes' [所有exec命令都有相同的错误]

服务器出错：tls：handshake未验证证书链' -

我如何解决这个问题，我正在寻找exec结果

Answer 1

我没有看到这个确切的问题，但我有两个建议：

尝试使用Go 1.4.2构建，即what our CI is currently using。
尝试升级和链接OpenSSL（brew update && brew upgrade openssl && brew link --force openssl），并确保Go使用它而不是系统openssl（这是古老的）。
