我正在尝试使用 helm 启动 WSO2 身份服务器，并且在 MAILTO 发送程序启动后服务器突然关闭。
我正在按照 wso2 文档here使用 helm 进行设置。
sql server 和一切都开始正常。当我查看身份服务器 Pod 的日志时，跟踪显示启动关闭挂钩的错误。没有其他信息说明其背后的原因。
以下是用于部署服务器的 helm 图表：

对于容器来说，生命周期钩子定义如下。根据共享数据，容器似乎尚未在时间间隔内启动，并且已触发生命周期挂钩。
lifecycle:
preStop:
exec:
command:
- sh
- '-c'
- ${WSO2_SERVER_HOME}/bin/wso2server.sh stop
您可以移除探针并让容器先启动，或者您也可以调整探针配置。
