🗓️实验环境

*OS名称*	Microsoft Windows 11 家庭中文版
*系统类型*	x64-based PC
*Docker版本*	Docker version 24.0.6, build ed223bc
*minikube版本*	v1.32.0

🖇️创建 kustomization.yaml

你可以通过 kustomization.yaml 中的生成器创建一个 Secret存储密码或密钥敏感数据对象。
kustomization.yaml

cat <<EOF >./kustomization.yaml
secretGenerator:
- name: mysql-passliterals:- password=YOUR_PASSWORD   #自定义密码
EOF

🗒️MySQL 和 WordPress 的资源配置

MySQL 容器将 PersistentVolume 挂载在 /var/lib/mysql。 MYSQL_ROOT_PASSWORD 环境变量根据 Secret 设置数据库密码。
mysql-deployment.yaml

apiVersion: v1
kind: Service
metadata:name: wordpress-mysqllabels:app: wordpress
spec:ports:- port: 3306selector:app: wordpresstier: mysqlclusterIP: None
---
apiVersion: v1

PersistentVolume 挂载到 /var/www/html，用于保存网站数据文件。 WORDPRESS_DB_HOST 环境变量设置上面定义的 MySQL Service 的名称，WordPress 将通过 Service 访问数据库。 WORDPRESS_DB_PASSWORD 环境变量根据使用 kustomize 生成的 Secret 设置数据库密码。
wordpress-deployment.yaml

apiVersion: v1
kind: Service
metadata:name: wordpresslabels:app: wordpress

将内容追加到 kustomization.yaml：

cat <<EOF >>./kustomization.yaml
resources:- mysql-deployment.yaml- wordpress-deployment.yaml
EOF

应用目录下文件：

rkun1@LAPTOP-TUS5FU0D MINGW64 ~/minikube-env
$ ls
kustomization.yaml  mysql-deployment.yaml  wordpress-deployment.yaml rkun1@LAPTOP-TUS5FU0D MINGW64 ~/minikube-env
$ kubectl apply -k ./

service/wordpress created
service/wordpress-mysql created
persistentvolumeclaim/mysql-pv-claim created
persistentvolumeclaim/wp-pv-claim created
deployment.apps/wordpress created
deployment.apps/wordpress-mysql created

📌验证信息

rkun1@LAPTOP-TUS5FU0D MINGW64 ~/minikube-env

本地minikube只能使用NodePort，运行以下命令以获取 WordPress 服务的 IP 地址

minikube service wordpress --url

$ minikube service wordpress --url
W1119 20:15:12.068839   25968 main.go:291] Unable to resolve the current Docker CLI context "default": context "default": context not found: open C:\Users\rkun1\.docker\contexts\meta\37a8eec1ce19687d132fe29051dca629d164e2c4958ba141d5f4133a33f0688f\meta.json: The system cannot find the path specified.
http://127.0.0.1:49401
❗  因为你正在使用 windows 上的 Docker 驱动程序，所以需要打开终端才能运行它。

使用浏览器访问：

数据存储在mysql服务中，mysql使用的存储资源是从环境获取的

查看PV信息：

进入minikube虚拟环境，可以查看到pv所挂载的目录：

rkun1@LAPTOP-TUS5FU0D MINGW64 ~
$ minikube ssh

docker@minikube:~$ cd /tmp/hostpath-provisioner/default
docker@minikube:/tmp/hostpath-provisioner/default$ ls

进入目录可以查看到mysql的一些配置文件以及数据：

docker@minikube:/tmp/hostpath-provisioner/default$ cd mysql-pv-claim/
docker@minikube:/tmp/hostpath-provisioner/default/mysql-pv-claim$ ls
