使用docker pull从镜像仓库拉取镜像时报错如下：

[root@docker-registry ~]# docker pull Using default tag: latestTrying 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

解决办法：

[root@docker-registry ~]# yum install bind-utils                          // 安装dig工具[root@docker-registry ~]# dig @114.114.114.114 registry-1.docker.io ; < <>> DiG 9.9.4-RedHat-9.9.4-61.el7_5.1 < <>> @114.114.114.114 registry-1.docker.io; (1 server found);; global options: +cmd;; Got answer:;; ->>HEADER< <- opcode: QUERY, status: NOERROR, id: 51198;; flags: qr rd ra; QUERY: 1, ANSWER: 8, AUTHORITY: 0, ADDITIONAL: 1 ;; OPT PSEUDOSECTION:; EDNS: version: 0, flags:; udp: 4096;; QUESTION SECTION:;registry-1.docker.io.

选择上面命令执行结果中的一组解析放到本机的/etc/hosts文件里做映射

[root@docker-registry ~]# vim /etc/hosts54.175.43.85    registry-1.docker.io

接着再进行docker pull镜像下载操作

[root@docker-registry ~]# docker pull centosUsing default tag: latestTrying to pull repository docker.io/library/centos ...latest: Pulling from docker.io/library/centosaeb7866da422: Pull completeDigest: sha256:67dad89757a55bfdfabec8abd0e22f8c7c12a1856514726470228063ed86593bStatus: Downloaded newer image for docker.io/centos:latest [root@docker-registry ~]# docker imagesREPOSITORY           TAG                 IMAGE ID            CREATED             SIZEdocker.io/centos     latest              75835a67d134        3 weeks ago         200 MB
