二、安装mysql

1、拉取镜像

#添加仓库
helm repo add bitnami https://charts.bitnami.com/bitnami#搜索镜像
helm search repo mysql#拉取镜像
helm pull bitnami/mysql --version  12.0.0#加压文件
tar -zxf mysql-12.0.0.tgz

2、修改配置文件

3、创建mysql-secret

apiVersion: v1
kind: Secret
metadata:name: mysql-secretnamespace: mysql8labels:app: mysql
type: Opaque
data:password: MTIzNDU2 # echo -n "123456"mysql-root-password: MTIzNDU2mysql-replication-password: MTIzNDU2

4、安装

#创建ns
kubectl create ns mysql8
#创建secretkubectl create -f mysql-secret.yaml#安装mysql8helm install mysql ./mysql -n mysql8 #查看资源kubectl get all -n mysql8
