1.创建spring boot项目

https://start.spring.io/

pom.xml文件新增docker支持 

    <build>

        <plugins>

            <plugin>

                <groupId>org.springframework.boot</groupId>

                <artifactId>spring-boot-maven-plugin</artifactId>

            </plugin>

            <plugin>

                <groupId>com.spotify</groupId>

                <artifactId>docker-maven-plugin</artifactId>

                <version>1.0.</version>

                <configuration>

                    <imageName>${docker.image.prefix}/${project.artifactId}</imageName>

                    <dockerDirectory>src/main/docker</dockerDirectory>

                    <resources>

                        <resource>

                            <targetPath>/</targetPath>

                            <directory>${project.build.directory}</directory>

                            <include>${project.build.finalName}.jar</include>

                        </resource>

                    </resources>

                </configuration>

            </plugin>

        </plugins>

    </build>
    <properties>

        <java.version>1.8</java.version>

        <docker.image.prefix>springboot</docker.image.prefix>

    </properties>

添加swagger支持 

<dependency>

            <groupId>io.springfox</groupId>

            <artifactId>springfox-swagger2</artifactId>

            <version>2.5.</version>

        </dependency>

        <!-- swagger-ui -->

        <dependency>

            <groupId>io.springfox</groupId>

            <artifactId>springfox-swagger-ui</artifactId>

            <version>2.5.</version>

        </dependency>

开启swagger，并创建测试控制器 

@EnableSwagger2

@SpringBootApplication

public class Application {

    public static void main(String[] args) {

        SpringApplication.run(Application.class, args);

    }

}
@Controller

@RequestMapping(value = "/test")

public class TestController {

    @RequestMapping(value = "/fun", method = RequestMethod.GET)

    @ResponseBody

    public String fun(@RequestParam(name = "str") String str) {

        String hostAddress = "";

        try {

            InetAddress address = InetAddress.getLocalHost();//获取的是本地的IP地址

            hostAddress = address.getHostAddress();

        } catch (Exception ex) {

        }

        return hostAddress + "返回：" + str;

    }

}

2.docker开始部署springBoot项目

进入发布服务器，创建目录，并新建Docker编译支持，Dockerfile文件 

# From java image, version : 8

#指定镜像，这里用网易云仓库的java8镜像

FROM hub.c.163.com/library/java:8-jre

# 挂载test-docker目录

VOLUME /tmp

# COPY or ADD to image

COPY example.dockertest-0.0.1-SNAPSHOT.jar app.jar

ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

使用Docker创建镜像 

 docker build -t service-test .

-t代表要构建的镜像的tag

.代表当前目录，也就是Dockerfile所在的目录。

查看镜像列表

运行镜像并测试是否成功 

docker run -d -p : service-test

curl http://192.168.50.23:8080/test/fun?str=aaa

curl http://192.168.50.23:8081/test/fun?str=aaa

curl http://192.168.50.23:8082/test/fun?str=aaa

将镜像文件上传docker镜像服务器，私有镜像服务器搭建参见 https://www.cnblogs.com/woxpp/p/11871886.html 

docker tag service-test 192.168.50.24:/service-test:latest

docker push 192.168.50.24:/service-test:latest

拉取进行并启动

测试是否可用
