如何解决Hazelcast无法在Kubernetes中启动
我有一个使用自定义证书初始化的HA Kubernetes集群。我想在其上运行Hazelcast，但是使用Kubernetes API发现Hazelcast成员时出错。 这是我的部署文件：

我已经在非定制证书ssl HA Kubernetes集群上测试了此部署文件，并且可以正常工作。

解决方法
Hazelcast Kubernetes发现插件不允许您指定证书的自定义位置。它们是always read的默认位置：/var/run/secrets/kubernetes.io/serviceaccount/ca.crt。
通过参数ca-certificate，您可以像显示的here那样内联证书，但不能指定证书的路径。
如果您认为此功能很有用，请在https://github.com/hazelcast/hazelcast-kubernetes处创建GH问题（您也可以随更改发送PR）。
