linux虚拟机部署docker时拉取image遇到的问题

1：防火墙问题
手动检查防火墙是否已经关闭
2：daemon.json问题

docker: Error response from daemon: Get "https://registry-1.docker.io/v2/": dial tcp 192.168.152.2:443: connect: connection refused.

解决

{   "registry-mirrors": ["https://ccr.ccs.tencentyun.com","https://registry.docker-cn.com","https://docker.mirrors.ustc.edu.cn","https://bytkgxyr.mirror.aliyuncs.com","http://hub-mirror.c.163.com"]
}

用以上内容即可
3：DNS解析问题

docker: Error response from daemon: Head "https://registry-1.docker.io/v2/library/mysql/manifests/latest": Get "https://auth.docker.io/token?scope=repository%3Alibrary%2Fmysql%3Apull&service=registry.docker.io": dial tcp: lookup auth.docker.io on 192.168.152.2:53: server misbehaving.

解决：

vim /etc/resolv.conf
添加：
nameserver 114.114.114.114
nameserver 8.8.8.8

dig @114.114.114.114 registry-1.docker.io

;; ANSWER SECTION:
registry-1.docker.io.	126	IN	A	54.196.99.49
registry-1.docker.io.	126	IN	A	3.219.239.5
registry-1.docker.io.	126	IN	A	34.226.69.105
选择其中一个ip，写入/etc/hosts中
vim /etc/hosts
54.196.99.49	registry-1.docker.io
