容器鉤子

容器鉤子分為post-start和pre-stop

post-start：容器啟動后執行的命令

pre-stop：容器關閉前執行的命令，可用于優雅關閉

#?分別定義兩個鉤子，啟動pod后更新index.html，關閉pod前正常關閉服務

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"

# 上圖可以看出，nginx在啟動之前，就被post-start改寫了index.html文件
