容器钩子

容器钩子分为post-start和pre-stop

post-start：容器启动后执行的命令

pre-stop：容器关闭前执行的命令，可用于优雅关闭

# 分别定义两个钩子，启动pod后更新index.html，关闭pod前正常关闭服务

vi post-pre.yaml 
apiVersion: v1
kind: Pod
metadata:name: life-demo
spec:containers:- name: lifecycle-demo-containerimage: 172.16.80.140/nginx/nginx:1.26imagePullPolicy: IfNotPresentlifecycle:postStart:exec:command: ["/bin/sh", "-c","echo 'lifecycle post-start' > /usr/share/nginx/html/index.html"]preStop:exec:command:- "/bin/sh"- "-c"- "nginx -s stop"

# 上图可以看出，nginx在启动之前，就被post-start改写了index.html文件
