docker拉取镜像报错

环境

虚拟机CentOS7

安装好docker之后拉取emby镜像报错：

[root@localhost ~]# docker pull yukinococo/emby_crack
Using default tag: latest
Error response from daemon: Head https://registry-1.docker.io/v2/yukinococo/emby_crack/manifests/latest: read tcp 112.118.3.11:55128->34.238.187.50:443: read: connection reset by peer
[root@localhost ~]# vim /etc/resolv.conf

解决方案：

dig命令报错

[root@localhost ~]# dig @114.114.114.114 registry-1.docker.io
-bash: dig: command not found
[root@localhost ~]# yum -y install bind-utils

[root@localhost ~]# dig @114.114.114.114 registry-1.docker.io
