使用maven插件构建微服务的Docker镜像

1.在服务中pom中添加插件

<plugin>
<groupId>com.spotify</groupId>
<artifactId>docker-maven-plugin</artifactId>
<version>0.4.13</version>
<configuration>
<imageName>eureka</imageName>
<dockerDirectory>${project.basedir}/src/main/docker</dockerDirectory>
<dockerHost>http://Docker宿主机ip:2375</dockerHost>
<resources>
<resource>
<targetPath>/</targetPath>
<directory>${project.build.directory}</directory>
<include>${project.build.finalName}.jar</include>
</resource>
</resources>
</configuration>

</plugin>

2.添加src/main/docker source folder，并添加Dockerfile, 内容：

FROM java:8

VOLUME /temp

ADD eureka-service-1.0.jar app.jar
RUN bash -c 'touch /app.jar'

EXPOSE 8088

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

3.在本地使用： mvn clean package docker:build -DskipTests

如果你运气够好，上面三步应该就可以在本地构建镜像到服务器上。下面说一下我遇到的各种坑！！！

1)Failed to execute goal com.spotify:docker-maven-plugin:0.4.13:build (default-cli) on project springb: Exception caught: java.util.concurrent.ExecutionException: com.spotify.docker.client.shaded.javax.ws.rs.ProcessingException: org.apache.http.conn.HttpHostConnectException: Connect to localhost:2375 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused: connect ====》这个问题可以通过在pom中配置<dockerHost>http://Docker宿主机ip:2375</dockerHost> 来解决，但是这样做可能会报出下面的错，我就是这样

2） Failed to execute goal com.spotify:docker-maven-plugin:0.4.13:build (default-cli) on project eureka-service: Exception caught: Timeout: GET http://10.61.213.105:2372135/version: com.spotify.docker.client.shaded.javax.ws.rs.ProcessingException: org.apache.http.conn.ConnectTimeoutException: Connect to 10.61.213.105:2375 [/10.61.213.105] failed: connect timed out

==========================下面是解决方案===============================

/usr/lib/systemd/system/docker.service添加属性：

把ExecStart=/usr/bin/dockerd-current 换成 ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock，原本的\要保留然后systemctl daemon-reload。重启docker，telnet成功(相信我这里有很多坑)，效果图如下：![在这里插入图片描述](https://img-blog.csdnimg.cn/20200219224008611.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zMjgyMjc1OQ==,size_16,color_FFFFFF,t_70)

3）如果上面问题依然存在，需要检查服务器端口有没有对远程连接开放，可能会需要对防火墙做一些操作，这些可以在网上找到一些资料，最后祝大家好运，能用jenkins就别使用这种方式了。。。
