Here we are only creating a single replica, so we don’t have any issue with our read-write volume

We are passing a Environment variable in our MySQL container for its root password using a secret object.

Now, if you look at our mysql-deployment.yaml you can see we are associating our persistent volume object with this deployment and then mounting it inside the MySQL container

Now we will create mysql-service.yaml

This will create an internal service to access our MySQL deployment
