Hi @pacificsofttechltd,

This is what you’ll need to use

spring.datasource.url=jdbc:mysql://${MYSQL_HOST:localhost}:3306/db_example

You need to specify your spring.datasource.username and spring.datasource.password like the following

spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://${MYSQL_HOST:localhost}:3306/db_example
spring.datasource.username=springuser
spring.datasource.password=ThePassword

Regards,
KDSys
