在Docker容器上使用mysql数据库的spring引导应用程序Maven安装构建失败

要创建jar来为我的春季引导应用程序构建码头容器，我从eclipse运行Maven安装，但是生成失败，如下所示：

2020-07-18 20:49:03.551 ERROR 5920 --- [ restartedMain] o.s.boot.SpringApplication : Application run failed我用于spring引导应用程序的application.properties文件是：
spring.datasource.username=root
spring.datasource.password=ayush123
spring.datasource.url=jdbc:mysql://mysqldb:3306/employeedb
spring.datasource.platform=mysql
hibernate.hbm2ddl.auto=update
spring.jpa.generate-ddl=true
spring.datasource.hikari.initializationFailTimeout=-1我也尝试过使用spring.datasource.url=jdbc:mysql://mysqldb/employeedb
我创建了docker网络，并使用以下命令构建了MYSQL容器：
docker pull mysql:8.0
docker network create edrms-net
docker container run --name mysqldb --network edrms-net -e MYSQL_ROOT_PASSWORD=ayush123 -e MYSQL_DATABASE=employeedb -d mysql:8.0在docker container ls上，我可以看到MYSQL的部署和运行。
我完全迷失了，无法恢复。请帮帮我！

若要连接到码头容器内的mySql服务器，必须在运行要连接到服务器的容器时发布端口。
为此，请将--publish 3306:3306添加到您的停靠容器运行命令中。
