  • 由于打算将SpringBoot应用部署在quarkus应用所在电脑上，所以要先停掉quarkus应用，执行以下命令
sudo docker stop quarkus启动SpringBoot应用
  • 新建名为application.properties的配置文件，内容是数据库相关的参数，如下所示
spring.datasource.url=jdbc:postgresql://42.193.162.141:5432/quarkus_testspring.datasource.username=quarkusspring.datasource.password=123456spring.datasource.driver-class-name=org.postgresql.Driverspring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialectspring.jpa.properties.hibernate.hbm2ddl.auto=updatespring.datasource.hikari.maximum-pool-size=256
  • 我这里，application.properties的路径是：/home/lighthouse/config/springboot/application.properties
  • 检查application.properties文件的可读性，执行以下命令设置
sudo chmod a+r application.properties
  • 执行以下命令即可部署和启动springboot应用，注意application.properties文件的位置要换成您自己的配置文件路径
docker run -idt \--name springboot \-p 8080:8080 \-v /home/lighthouse/config/springboot/application.properties:/application/BOOT-INF/classes/application.properties \bolingcavalry/springboot-postgresql-demo:x64-0.0.3
  • 上述命令中，springboot应用的镜像bolingcavalry/springboot-postgresql-demo:x64-0.0.3是我提前准备好的，本篇只管使用即可，至于如何制作此镜像，接下来的文章会有详细说明
  • 看到以下日志，证明应用启动成功
