php fpm进程在Kubernetes中接收SIGKILL信号
我已经创建了ubuntu docker映像，其中配置了Nginx、PHP和PHP fpm。当我在Docker实例上运行它时，它工作正常 但是当我在kubernetes中运行相同的映像时，php fpm进程接收到SIGKILL（9）信号，我们得到502个网关错误 我猜是库伯内特斯向库伯内特斯吊舱发送SIGKILL信号。我没有在kubernetes模板中使用任何准备就绪和活跃性探测 谢谢你的帮助。提前谢谢 有关详细信息，请在下面查找docker文件和php fpm日志 Dockerfile supervisor.conf php-fpm.log Nginx日志 Pod定义php fpm进程在Kubernetes中接收SIGKILL信号,php,nginx,kubernetes,kubernetes-helm,Php,Nginx,Kubernetes,Kubernetes Helm,我已经创建了ubuntu docker映像，其中配置了Nginx、PHP和PHP fpm。当我在Docker实例上运行它时，它工作正常 但是当我在kubernetes中运行相同的映像时，php fpm进程接收到SIGKILL（9）信号，我们得到502个网关错误 我猜是库伯内特斯向库伯内特斯吊舱发送SIGKILL信号。我没有在kubernetes模板中使用任何准备就绪和活跃性探测 谢谢你的帮助。提前谢谢 有关详细信息，请在下面查找docker文件和php fpm日志 Dockerfile supe

Rahul考虑到您希望在PHP fpm管理的内部运行多个PHP进程，您的内存限制非常低。您的进程很可能由于此内存限制而被终止。我建议将内存限制切换到400Mi之类的值，然后再次检查。请提供您的pod（或部署）定义和
