我在Requirements.yaml中添加了稳定/ mysql图表
dependencies:
- name: mysql
version: 1.4.0
repository: https://kubernetes-charts.storage.googleapis.com
condition: global.install_mysql
创建PVC
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: mysql-azure-managed-disk
spec:
accessModes:
- ReadWriteOnce
storageClassName: managed-premium
resources:
requests:
storage: 5Gi
并在mycharts values.yaml中增加了持久性
mysql:
persistence:
enabled: false
storageClass: managed-premium
existingClaim: mysql-azure-managed-disk
accessMode: ReadWriteOnce
size: 1Gi
annotations: {}
[当我安装mychart helm install --name mychart .时，图表已成功安装，我的另一个Pod也能够使用密码输入密码连接到mysql Pod。
但是当我删除图表并再次安装时，新的Pod无法连接到mysql Pod。
有人遇到这个问题吗？
这是第一次登录

以某种方式第二次我的应用程序pod无法连接到mysql的pod
即使我删除图表并重新安装新的，当我在values.yaml中添加mysqlRootPassword时。每次都连接到mysql pod。
