⚫ OCI：Open Container Initiative的简称，由Linux基金会主导开发OCI规范和标准，目的是
围绕容器格式和Runtime（运行时）制定的一个开放的工业化标准。
⚫ Containerd：Docker为了兼容OCI标准，将容器Runtime及其管理功能从Docker守护进程中
剥离出来，用于不启动Docker也能直接通过Containerd来管理容器。
⚫ RunC：Docker按照OCF（Open Container Format）开放容器格式标准制定的一个轻量级
工具，可以使用RunC不通过Docker引擎即可实现容器的启动、停止和资源隔离等功能。 文 章 源 自 note.t4x.orgByrd's Blog-https://note.t4x.org/cloud/about-config-docker/
