kubectl create secret generic mysql-pass --from-literal=password=YOUR_PASSWORD

把mysql.tar.gz和wordpress.tar.gz上传到K8s工作节点，手动解压即可：
通过网盘分享的文件：wordpress.tar.gz

通过网盘分享的文件：mysql.tar.gz
链接: https://pan.baidu.com/s/1NVw3fULvQ3NOAAKtjU7nOw?pwd=8r2v 提取码: 8r2v

docker load -i mysql.tar.gz
docker load -i wordpress.tar.gz
ctr –n=k8s.io images import mysql.tar.gz
ctr –n=k8s.io images import wordpress.tar.gz
