What this article shares with you is about how to practice MySQL chart. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

Preparation before chart installation

As a preparation, you need to know how to use chart before installation. This information is usually recorded in values.yaml and README.md. In addition to downloading the source file and viewing it, performing helm inspect values may be a more convenient way.

The output is actually the content of values.yaml. Read the notes to know which parameters are supported by MySQL chart and what preparations need to be made before installation. Part of it is about storage:

Create a PV mysql-pv:

MysqlRootPassword is set to abc123. In addition,-n sets release to my, and the names of all kinds of resources are my-mysql.

You can view the latest status of chart through helm list and helm status.

Wait some time for the upgrade to succeed.

The rollback succeeded and MySQL reverted to 5.7.14.

At this point, I believe you already know how to use chart.

The above is how to practice MySQL chart, the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
