Spring Boot Docker

开发环境

开发工具： Intellij IDEA 2018.2.6

springboot: 2.0.6.RELEASE

jdk： 1.8.0_192

maven: 3.6.0

docker: Docker Engine - Community 18.09.0

搭建项目

由于使用了 Spring Cloud 的Eureka所以加了 eureka 的依赖，基本不需要多加额外的配置

application.yml

启动类

/** *  * * @author Leone * @since 2018-03-06 **/@EnableEurekaServer@SpringBootApplicationpublic class DockerApplication {    public static void main(String[] args) {        SpringApplication.run(DockerApplication.class, args);    }}

Dockerfile

在src/main/docker目录下(没有则创建此目录)创建Dockerfile文件然后把maven编译后的jar文件拷贝到和Dockerfile同级的目录

# 基于哪个镜像FROM java:8# 将本地文件夹挂载到当前容器VOLUME /tmp# 维护者信息MAINTAINER leone "exklin@gmail.com"# 拷贝文件到容器ADD spring-docker.jar eureka.jar# 执行命令RUN bash -c 'touch eureka.jar'# 声明端口EXPOSE 8761# 配置容器启动后执行的命令ENTRYPOINT ["java","-jar","-Djava.security.egd=file:/dev/./urandom","eureka.jar"]

安装 idea Docker 插件后需要在 windows 下安装 Docker 在docker 插件的 Deploy configuration 里面配置 docker 容器参数之后点击Run后就会顺序执行 Dockerfile 里面的命令就会启动这个docker容器。打开浏览器访问http://localhost:8761,
