配置master为镜像仓库

#master节点

#替换配置文件中的这行，使用下面的内容
#配置docker加速，和信任私有仓库（注意，系统自带或者我们后安装的docker版本，配置文件是/etc/docker/daemon.jason）
[root@k8s-master ~]#vim /etc/sysconfig/docker
OPTIONS=‘--selinux-enabled --log-driver=journald --signature-verification=false --registry-mirror=https://aeckruos.mirror.aliyuncs.com --insecure-registry=192.168.6.129:5000‘

#重启docker
[root@k8s-master ~]#systemctl restart docker

#起仓库容器（普通的registry） 前面docker文件里面有单独一遍讲解如何安装registry，这里不在描述
[root@k8s-master ~]# docker run -d -p 5000:5000 --restart=always --name registry -v /opt/myregistry:/var/lib/registry registry
Unable to find image ‘registry:latest‘ locally

仓库搭好了。
===============================
再次确认k8s三台的起的容器能网络是通的：
[root@k8s-master ~]# docker run -it busybox /bin/sh #三台都起一个容器，互相ping
/ # ping 172.16.16.2
PING 172.16.16.2 (172.16.16.2): 56 data bytes
^C
--- 172.16.16.2 ping statistics ---

round-trip min/avg/max = 0.538/0.824/1.728 ms
/ # ^C
/ # ping 172.16.83.2
