先下载实战-在k8s平台部署个人博客-资源包

再K8s部署个人博客

实验步骤如下：

[root@k8s-master]# 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：

[root@k8s-node1]# docker load -i mysql.tar.gz

[root@k8s-node1]# docker load -i wordpress.tar.gz

#部署服务

[root@k8s-master]# kubectl apply -f mysql.yaml

[root@k8s-master]# kubectl apply -f wordpress.yaml

#查看wordpress前端的service

[root@k8s-master ~]# kubectl get svc -l app=wordpress

备注；node_ip可以是K8s集群控制节点ip，也可以是工作节点ip
