使用docker pull從映象倉庫拉取映象時報錯如下：
[root@docker-registry ~]# docker pull centos
Using default tag: latest
Trying to pull repository docker.io/library/centos ...
Get https://registry-1.docker.io/v2/library/centos/manifests/latest: Get https://auth.docker.io/token?scope=repository%3Alibrary%2Fcentos%3Apull&service=registry.docker.io: net/http: TLS handshake timeout

解決辦法：

[root@docker-registry ~]# yum install bind-utils                          // 安裝dig工具
[root@docker-registry ~]# dig @114.114.114.114 registry-1.docker.io

選擇上面命令執行結果中的一組解析放到本機的/etc/hosts檔案裡做對映
[root@docker-registry ~]# vim /etc/hosts
54.175.43.85    registry-1.docker.io

接著再進行docker pull映象下載操作
[root@docker-registry ~]# docker pull centos
Using default tag: latest
Trying to pull repository docker.io/library/centos ...
