一、工程結構

二、Pom配置

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <!-- tag::plugin[] -->
            <
 
plugin>
                <groupId>com.spotify</groupId>
                <artifactId>docker-maven-plugin</artifactId>
                <version>0.4.3</version>
                <configuration>
                    <imageName>${docker.image.prefix}/${project.artifactId}</
 
imageName>
                    <dockerDirectory>src/main/docker</dockerDirectory>
                    <skipDockerBuild>false</skipDockerBuild>
                    <resources>
                        <resource>
                            <targetPath>/</targetPath
 
>
                            <directory>${project.build.directory}</directory>
                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>
                </configuration>
            </plugin>
            <!-- end::plugin[] -->
        </plugins>
    </build>

yml配置信息

server:
  port: 8661
#  context-path: /hello

eureka:
  instance:
    prefer-ip-address: true
  client:
    registerWithEureka: false
    fetchRegistry: false

三、dockerfile信息

創建dockerfile文件，位置：src/main/docker

FROM frolvlad/alpine-oraclejdk8:slim
VOLUME /tmp
ADD eureka-server-docker-0.0.1-SNAPSHOT.jar app.jar
#RUN bash -c ‘touch /app.jar‘
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
EXPOSE 8761

四、修改遠程Linux服務器docker配置，作者版本為Centos7

1、編輯docker.service文件

vi /usr/lib/systemd/system/docker.service

在ExecStart這一行後面追加-H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock

ExecStart=/usr/bin/dockerd-current           -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock           --add-runtime docker-runc=/usr/libexec/docker/docker-runc-current           --default-runtime=docker-runc           --exec-opt native.cgroupdriver=systemd           --userland-proxy-path=/usr/libexec/docker/docker-proxy-current           $OPTIONS           $DOCKER_STORAGE_OPTIONS           $DOCKER_NETWORK_OPTIONS           $ADD_REGISTRY           $BLOCK_REGISTRY           $INSECURE_REGISTRY

2、重啟docker服務

service docker restart

3、查看端口是否啟動

netstat -anp|grep 2375

4、防火墻開放2375端口

firewall-cmd --zone=public --add-port=2375/tcp --permanent

firewall-cmd --reload

五、Windows增加DOCKER_HOST環境變量

六、Maven打包構建

mvn clean package docker:build -DskipTests

七、啟動容器

docker run --name eureka-server -p 8661:8661 -d mydocker/eureka-server-docker

八、訪問測試

spring could Windows打包構建docker鏡像到linux
