拉取docker中的鏡像時報錯:
[root@master ~]# docker pull docker.io/centos:latest
Trying to pull repository docker.io/library/centos ...
Pulling repository docker.io/library/centos
Error while pulling image: Get https://index.docker.io/v1/repositories/library/centos/images: x509: certificate is valid for ruijie, not index.docker.io
解決辦法:
1.執行 yum install bind-utils,安裝dig工具。
[root@master ~]# yum install bind-utils
已加載插件：fastestmirror, langpacks
Loading mirror speeds from cached hostfile
軟件包 32:bind-utils-9.11.4-9.P2.el7.x86_64 已安裝並且是最新版本
無須任何處理
2.通過dig @114.114.114.114 registry-1.docker.io找到可用IP
dig @114.114.114.114 registry-1.docker.io
; <<>> DiG 9.11.4-P2-RedHat-9.11.4-9.P2.el7 <<>> @114.114.114.114 registry-1.docker.io

3.選擇上面命令執行結果中的一組解析放到本機的/etc/hosts文件里做映射
vim /etc/hosts
插入 34.232.31.24 registry-1.docker.io
然后保存。
4.接着執行拉取鏡像的操作。
docker pull docker.io/centos
Using default tag: latest
Trying to pull repository docker.io/library/centos ...
latest: Pulling from docker.io/library/centos
Digest: sha256:f94c1d992c193b3dc09e297ffd54d8a4f1dc946c37cbeceb26d35ce1647f88d9
5.檢測是否拉取成功。
[root@master ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
docker.io/centos latest 0f3e07c0138f 11 weeks ago 219.5 MB
