使用Docker部署 spring-boot maven应用的方法

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-web</artifactId>
</dependency>

@Controller
public class HelloWorld{
  @GetMapping("/hello")
  public void helloworld(HttpServletResponse response) throws IOException {
    response.getWriter().write("Hello Spring-boot");
  }
}

FROM frolvlad/alpine-oraclejdk8:slim
VOLUME /tmp
ADD demo-0.0.1-SNAPSHOT.jar app.jar
RUN sh -c 'touch /app.jar'
ENV JAVA_OPTS=""
ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar" ]

cd Z:/Desktop/springboot-demo

mvn package -Dmaven.test.skip=true docker:build

##最好添加--name参数
docker run --name=springboot-docker-demo -p 8080:8080 -t ramer/demo

cmd: docker ps

cmd: docker start/stop/restart/rm CONTAINER_ID/NAME
