I tried to run all images regarding Spring Boot Microservices on Kubernetes.

When I run kubectl apply -f k8s,

I get this issue for order service, payment service, auth service and lastly product service.

Here is the issue shown below.

Caused by: java.sql.SQLException: Access denied for user 'springmicroserviceuser'@'172.17.0.6' (using password: YES)

How can I define a command to create user and password in MySQL deployment yaml file.

Here is the file shown below.
