项目结构:
在main 目录下创建 docker 文件夹, 再在里面创建一个Dockerfile文件,文件内容为:
FROM openjdk:8-jdk-alpine VOLUME /tmp ADD deploy-0.0.1-SNAPSHOT.jar app.jar ENTRYPOINT ["java","-jar","/app.jar"]
- 基础镜像信息
- 数据持久化的方式
- 重命名为app.jar
- 启动运行 java -jar app.jar
Application 文件
@SpringBootApplication @RestController public class DeployApplication { @RequestMapping("/") public String demo() { return "第一次使用 docker 部署 springboot "; } public static void main(String[] args) { SpringApplication.run(DeployApplication.class, args); } }
application.properties
server.port=8080
勾选这个选项
命令行进入项目目录输入:mvn clean
再执行:mvn package
部署上docker
在命令行输入:mvn package docker:build
运行没有报错就没有问题了。
命令行运行:docker images 查看当前所有镜像
再输入:docker run -p 8080:8080 -t -i springboot/deploy 运行镜像 (-p 指定端口映射, -t 容器重新分配一个伪输入终端 ,-i 以交互模式运行容器)
再输入:docker ps 查看我们正在运行的容器
在浏览器输入:http://localhost:8080/
