操作场景
本文介绍如何把业务镜像分层构建与管理，使用 TCR 高效的管理各类容器镜像的最佳实践。
容器镜像分层的优势
共享资源，提升资源利用率。
镜像管理规范化与标准化，便于 Devops 落地实施。
TCR 的免运维、镜像加速，可轻松提升大规模镜像分发速度 5-10 倍。
TCR 企业版内实例、命名空间、镜像仓库等资源的读写操作已接入操作审计，通过控制台进入审计日志即可查看相关操作记录。
前提条件
如果使用子账号进行操作，请参考 企业版授权方案示例 提前为子账号授予对应实例的操作权限。
说明：
已有容器镜像服务也适用，修改镜像仓库地址即可。

alpine/Dockerfile ：使用 alpine 官方提供的 3.13 docker 镜像 构建，添加常用运维工具与中文支持等配置。
centos-7.8/Dockerfile ：使用 Centos 官方提供的 7.8 docker 镜像 构建，添加常用运维工具与中文支持等配置。
Dockerfile-alpine-kona ：使用 Dockerfile-alpine 和 TencentKona 8.0.5 二进制包 构建，为控制镜像大小对 Kona 做了部分裁剪。
Dockerfile-jmeter-base ：基于 Jmeter 官方提供的 5.4.1 二进制包 构建。
Dockerfile-jmeter-grafana-reporter ：基于 Grafana-Reporter 构建 ，提供 Grafana 仪表板生成 Jmeter PDF 报告的功能。
Dockerfile-jmeter-master ：基于 Jmeter-base 镜像构建，实现 Jmeter 分布式压测 Master 的功能。
Dockerfile-jmeter-slave ：基于 Jmeter-base 镜像构建，实现 Jmeter 分布式压测 Slave 的功能。
Dockerfile-alpine-nginx ：基于 Dockerfile-alpine 构建 ，添加 nginx 配置初始化与日志规范等配置。
Dockerfile-alpine-kona-skywalking ：使用 Dockerfile-alpine-kona 和 skywalking 官方提供的 8.5 二进制包 构建。
