maven docker plugin 常见问题解决

1. maven 项目必须使用小写，不然会一直有500 的错误

500: HTTP 500InternalServerError

2. docker server 连接数超了

Failed to execute goal com.spotify:docker-maven-plugin:0.4.11:build (default-cli) on project activityservice:Exception caught: java.util.concurrent.ExecutionException: com.spotify.docker.client.shaded.javax.ws.rs.ProcessingException: java.io.IOException:No such file or directory

解决方法：
最简单的方法, 重启docker 服务

systemctl restart docker

3. maven 账户配置问题

<plugin>

<groupId>com.spotify</groupId>

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

<version>0.4.11</version>

<configuration>

<imageName>XXXXXXXXXX/activitycenter/${project.artifactId}</imageName>

<imageTags>activitycenter-${project.version}</imageTags>

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

<serverId>docker-image</serverId>

<useConfigFile>true</useConfigFile>

<resources>

<resource>

<targetPath>/</targetPath>

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

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

</resource>

</resources>

</configuration>

</plugin>

serverId docker-image 配置信息账户信息：

<server>

<id>docker-image</id>

<username>admin</username>

<password>XXXXX</password>

<configuration>
