用Jib配置idea的maven项目中，实现springboot、tomcat 来build镜像
2. Jib+Maven+Springboot 实践代码例子
2.1在maven项目中的pom.xml文件中配置Jib插件
<plugin>
<groupId>com.google.cloud.tools</groupId>
<artifactId>jib-maven-plugin</artifactId>
<version>1.0.1</version>
</plugin>
pluginManagement & plugins 如果在idea右边不显示插件jib，注意把pluginManagement注释了，就可以正常显示了
2.2 配置详情
1.这里有一个验证直接使用用户名和密码，来替代credHelper使用。验证成功后可以直接从Docker hub或者网易hub.c.163.com上获取官方镜像（依据个人喜好配置对应的auth）
<!--jib 构建插件-->
<plugin>
<groupId>com.google.cloud.tools</groupId>
<artifactId>jib-maven-plugin</artifactId>
<version>1.0.1</version>
<configuration>
<from>
<image>openjdk:alpine</image>
<!--直接指定凭证（替代credHelper）-->
<auth>
<username>${registry_username}</username>
<password>${registry_password}</password>
</auth>
</from>
<to>
<image>${registry_url}/${project.artifactId}</image>
<tags>
<tag>latest</tag>
</tags>
</to>
<container>
<mainClass>com.ecdata.CmpApplication</mainClass>
<!--使用当前时间-->
<useCurrentTimestamp>true</useCurrentTimestamp>
<!--容器在运行时暴露的端口-->
<ports>
<port>8088</port>
</ports>
</container>
<!--如果私有镜像仓库没有启用https，设置allowInsecureRegistries参数为true-->
<allowInsecureRegistries>false</allowInsecureRegistries>
</configuration>
<!--绑定jib:build到 Maven生命周期，例如package-->
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>dockerBuild</goal>
</goals>
</execution>
</executions>
</plugin>
已绑定jib:build到 Maven生命周期package，所以直接运行package

2.3 验证生成好的镜像：
sai:~ ws$ docker images | grep 31.16.14.55/szy/cmp
31.16.14.55/szy/cmp latest 70440c0ad660 6 minutes ago 213MB
sai:~ ws$
2.4 push镜像到镜像仓库：
sai:~ ws$ docker push31.16.14.55/szy/cmp
