 __Caution__: In case of using `MySQL` as Control Plane's datastore, please note that the implementation of PipeCD requires some features that only available on [MySQL v8](https://dev.mysql.com/doc/refman/8.0/en/), make sure your MySQL service is satisfied the requirement.

 ### 3. Accessing the PipeCD web
 
 If your installation was including an [ingress](https://github.com/pipe-cd/pipecd/blob/master/manifests/pipecd/values.yaml#L7), the PipeCD web can be accessed by the ingress's IP address or domain.
