这是一篇关于如何实现Docker镜像的持续集成与持续交付的交付文档，产生这份文档的缘由是之前服务过的郑州市某家欠薪公司的及其客户一再打电话给我，希望我能提供一份相关操作文档。在我没有收到赔偿款和正式道歉视频之前，这份文档我不会披露更多细节，但可以在此大概描述一下关于Jenkins、Maven和Docker的部分。
什么是CI？CI全拼是Continuous Integration，译作持续集成，在业务语境中主要针对代码编写人员及测试人员，他们需要不定时地频繁提交代码、测试代码，以便快速发现软件工程中的代码质量问题并进行修复。这部分工作和平台运维没有任何关系，但和软件产品运维有较大关系。
什么是CD？CD全拼是Continuous Deployment或Continuous Delivery，根据协同分工的组织划分不同，CD有不同含义。在规模适当、权责明晰的产品型组织团队中，CD指代Continuous Deployment，意在将软件工程项目灵活部署到任意环境，主要供内部测试团队或尝鲜用户使用。而在规模较小而指责不清晰的管理型组织团队中，CD指代Continuous Delivery，意指将成熟的、定型的软件产品交付给终端使用者，涵盖了软件工程的部署和维保培训。在河南省的IT环境中，CD偏向于指代Continuous Delivery，有时也兼指Continuous Deployment和Continuous Delivery，比如我曾服务过的郑州市某ZY公司，总计职员27人，每个技术人员对应了5个管理人员，号称“人人皆可管理技术”。
该项目的工作流程描述：代码由《开发电脑》提交至《git》；触发《Jenkins》的自动代码编译并构建镜像，而后将镜像推送到《docker》仓库；《测试环境或生产环境》从《docker》仓库中拉取镜像进行《部署》。
项目实施环境：

Host OS：CentOS 7 1804 64Bit
 Package：git、JDK、Maven、Tomcat、Jenkins
 Role：Git/Registry、 Docker、Jenkins
 IP Range：192.168.207.177~192.168.207.180
