Docker pull拉取镜像报错“Error response from daemon: Get “https://registry-1.docker.io/v2”解决办法

一、报错信息

[root@node ~]# docker pull o2oa/o2server
Using default tag: latest
Error response from daemon: Head "https://registry-1.docker.io/v2/o2oa/o2server/manifests/latest": net/http: TLS handshake timeout

二、检查daemon.json 文件 1.编辑daemon.json

可额外添加阿里云的镜像加速

[root@node ~]# cat /etc/docker/daemon.json
{"registry-mirrors": ["https://registry.docker-cn.com","http://hub-mirror.c.163.com"]}

2.重启服务

systemctl daemon-reload
systemctl restart docker

三、查看dns解析

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

;  DiG 9.9.4-RedHat-9.9.4-72.el7  @114.114.114.114 registry-1.docker.io
; (1 server found)
