8>.docker镜像加速配置
此过程相对较简单，和Ubuntu配置镜像加速几乎雷同，可参考我的笔记:"https://www.cnblogs.com/yinzhengjie/p/12182645.html"
二.docker存储引擎
1>.官方推荐使用overlay2存储引擎
目前docker默认的存储引擎为overlay2，需要磁盘分区支持d-type文件分层功能，因此需要系统磁盘的额外支持。
官方文档关于docker存储引擎的选择说明:https://docs.docker.com/storage/storagedriver/select-storage-driver/
2>.官网提示xfs文件系统格式需要添加"ftype=1"参数，否则在启动容器的时候会报错哟
docker官方推荐首选存储引擎为overlay2其次为devicemapper，但是devicemapper存在空间方便的一些限制，虽然开源通过后配置解决但官方依然推荐使用overlay2。
如果docker数据目录是一块单独的磁盘分区而且是xfs格式的，那么需要在格式化的时候加上"-n ftype=1",否则后期在启动容器的时候会报错不支持(" ... without d-type support."),这一点官网也有声明，如下图所示。
3>.centos 7.2安装docker默认的存储引擎是"devicemapper"(生产环境建议使用较新版本的CentOS 7.6发行版本)

Docker version 19.03.5进程关系
dockerd:
被客户端直接访问，其父进程为宿主机的systemd守护进程。
docker-proxy:
实现容器通信,其父进程为dockerd。
containerd:
被dockerd进程调用以实现runc交互。
containerd-shim:
真正运行容器的载体，其父进程为containerd。
2>.容器的创建于管理过程
创建容器通信过程如下:
1>.dockerd通过grpc和containerd模块通信，dockerd由libcontainerd负责和containerd进行交换，dockerd和containerd通信文件"/run/containerd/containerd.sock";
2>.containerd在dockerd启动时被启动,然后containerd启动grpc请求监听，containerd处理grpc请求，根据请求做相应动作;
3>.若是start或是exec容器,containerd拉起一个container-shim,并进行相应的操作。
4>.container-shim被拉起后，start/exec/create拉起runc进程，通过exit/control文件和containerd通信,通过父子进程关系和SIGCHLD监控容器中进程状态;
5>.在整个生命周期中，containerd通过epoll监控容器文件，监控容器事件。
