在前两篇文章2.Docker-resigtry2和3.SpringCloud-Eureka-Docker基础上进行配置。
例子使用com.spotify的maven插件，后续会对比研究io.fabric3的maven插件。
1.将插件配置到pom文件中
1.1 定义变量
配置hosts文件，加入59.110.14.120 docker.registry.server
<properties>
<docker.registry.server>docker.registry.server:5000</docker.registry.server>
</properties>
1.2 配置插件
<plugin>
<groupId>com.spotify</groupId>
<artifactId>docker-maven-plugin</artifactId>
<version>3.7.0</version>
<configuration>
<!--setting.xml的id-->
<serverId>docker.registry.server</serverId>
<!--推送到私有仓库-->
<imageName>${docker.registry.server}/${project.artifactId}</imageName>
<!--推送到本地仓库-->
<!--<imageName>${project.artifactId}</imageName>-->
<!--使用dockerfile构建镜像-->
<!--<dockerDirectory>docker</dockerDirectory>-->
<!--标签定义命令-->
<baseImage>openjdk:8u131-jdk-alpine</baseImage>
<entryPoint>["java", "-jar", "/${project.build.finalName}.jar"]</entryPoint>
<resources>
<resource>
<targetPath>/</targetPath>
<directory>${project.build.directory}</directory>
<include>${project.build.finalName}.jar</include>
</resource>
</resources>
</configuration>
<!--绑定生命周期-->
<executions>
<execution>
<id>build-image</id>
<phase>package</phase>
<goals>
<goal>build</goal>
</goals>
</execution>
<execution>
<id>tag-image</id>
<phase>package</phase>
<goals>
<goal>tag</goal>
</goals>
<configuration>
<image>${docker.registry.server}/${project.artifactId}</image>
<newName>${docker.registry.server}/${project.artifactId}</newName>
</configuration>
</execution>
</executions>
</plugin>
1.3 setting.xml配置
<server>
<id>docker.registry.server</id>
<username>gaojingyuan</username>
<password>testpwd</password>
<configuration>
<email>gaojingyuanyuan@126.com</email>
</configuration>
</server>
2.打包并推送image
mvn clean package -DpushImage
3. 服务器下载并启动服务
登录私服
docker login docker.registry.server:5000
下载镜像
docker pull docker.registry.server:5000/eurekaserverdocker
启动服务
docker stack deploy -c docker-compose.yml eurekaserverdocker
停止服务
docker stack rm eurekaserverdocker
常见错误：
1.执行mvn clean package -DpushImage5次retry后报错：
Failed to push docker.registry.server:5000/eurekaserverdocker, retrying in 10 seconds (5/5).
com.spotify.docker.client.exceptions.DockerException: no basic auth credentials
解决方法：
需要配置 vim .docker/config.json
把"docker.registry.server:5000": {},改为"https://docker.registry.server:5000": {},
"auths": {
"https://docker.registry.server:5000": {},
"https://index.docker.io/v1/": {}
},
https://github.com/spotify/docker-client/issues/804
2.执行mvn clean package -DpushImage报错：
Failed to execute goal com.spotify:docker-maven-plugin:1.0.0:tag (tag-image) on project eurekaserverdocker: Exception caught: Image not found: eurekaserverdocker: Request error: POST unix://localhost:80/images/eurekaserverdocker/tag?repo=docker.registry.server%3A5000%2Feurekaserverdocker: 404, body: {"message":"No such image: eurekaserverdocker:latest"}: HTTP 404 Not Found -> [Help 1]
解决方法：
需要正确配置<image>和<newName>
<execution>
<id>tag-image</id>
<phase>package</phase>
<goals>
<goal>tag</goal>
</goals>
<configuration>
<image>${docker.registry.server}/${project.artifactId}</image>
<newName>${docker.registry.server}/${project.artifactId}</newName>
</configuration>
</execution>
