Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured. Reason: Fa

I am developing a web application by using the Spring Boot, Spring Cloud Config and Docker. There are 3 projects. One is springboot web, Spring Cloud Config Server and MySql Database. I have use the Spring Boot Web with Themeleaf. It's basically perform a CRUD operation. In the development phase it's working fine. But when I deploy it in the Docker Spring-Boot webapp container(springboot-thymeleaf-web-crud) is giving me the following error--

APPLICATION FAILED TO START

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class

Action:

Consider the following: If you want an embedded database (H2, HSQL or Derby), please put it on the classpath. If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

I have created 3 container on Docker Compose file.

version: '3'

SpringBoot Web Application.properties is given below

spring.application.name=employee-service-mysql
server.port=8080
spring.cloud.config.uri=http://spring-cloud-config-server- 
employee:8888
spring.profiles.active=dev

SpringBoot Config Server is providing the following properties--

spring.datasource.url: jdbc:mysql://employee- 
database:3306/employee_directory? 
useSSL=false&serverTimezone=UTC&useLegacyDatetimeCode=false
spring.datasource.username: root
spring.datasource.password: rootpassword

spring.datasource.driver-class-name=com.mysql.jdbc.Driver

spring.tomcat.max-wait: 20000
spring.tomcat.max-active: 50
spring.tomcat.max-idle: 20
spring.tomcat.min-idle: 15

spring.jpa.properties.hibernate.dialect: 
org.hibernate.dialect.MySQL5InnoDBDialect
spring.jpa.show-sql: true
spring.jpa.format-sql: true
spring.jpa.database: MYSQL
spring.jpa.hibernate.ddl-auto: create

Out of these 3 containers Mysql and Spring Cloud Config container is working fine. But for the Spring Boot Webapp(springboot-thymeleaf-web-crud) is exiting by giving the error above.

Note: I use the same datasouce(Spring Data JPA) configuration on some other SpringBoot Rest API. Which are working fine. But this is the first time I am using SpringBoot Web. Do I need to explicitly define any configuration on the data-source.

Please help!!
