mysql配置文件'/opt/bitnami/mysql/conf/my.cnf'；是不可写的

现在我在kubernetes 1.15中使用此命令暂停mysql：

$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/mysql

mysql有状态集启动时，显示以下警告：

mysql 11:12:23.57 WARN  ==> The mysql configuration file '/opt/bitnami/mysql/conf/my.cnf' is not writable. Configurations based on environment variables will not be applied for this file.

我已经更改了kubernetes secrets中的mysql根密码，现在我无法使用新密码登录mysql，我应该怎么做才能修复它？我正在使用此命令登录：

mycli -h 172.30.184.8 -u mysql -p 9Ve5TEHgcY // way 1
mysql -h localhost -uroot -p 6a4vUXlTyeRvzizZ // way 2

显示错误：

Access denied for user 'root'@'localhost' (using password: YES)'

Readiness probe failed: mysqladmin: [Warning] Using a password on the command line interface can be insecure. mysqladmin: connect to server at 'localhost' failed error: 'Can't connect to local MySQL server through socket '/opt/bitnami/mysql/tmp/mysql.sock' (2)' Check that mysqld is running and that the socket: '/opt/bitnami/mysql/tmp/mysql.sock' exists!

我应该怎么做来修复警告？并成功登录mysql。这是有状态集定义：

现在我尝试在kubernetes中重新安装mysql，并使用初始密码登录mysql：

$ exec kubectl exec -i -t -n dabai-fat ajidou-mysql-0 -c mysql "--" sh -c "clear; (bash || ash || sh)"                                         ‹ruby-2.7.2›
sh: 1: clear: not found
