解决docker search influxdb 报错Error response from daemon: Get "https://index.docker.io/v1/search?q=influxdb&n=25": dial tcp: lookup index.docker.io on 192.168.12.2:53: read udp 192.168.12.128:39189->

解决docker search influxdb 报错Error response from daemon: Get "https://index.docker.io/v1/search?q=influxdb&n=25": dial tcp: lookup index.docker.io on 192.168.12.2:53: read udp 192.168.12.128:39189->192.168.12.2:53: i/o timeout

docker pull && docker search出现：Error response from daemon: Get https://index.docker.io/v1/search?q=nginx&n=25: dial tcp: lookup index.docker.io on 172.16.16.2:53: read udp 172.16.16.23:44580->172.16.16.2:53: i/o timeout此类报错
如图：

解决方法一：
这个是因为dns域名没有解析的原因，编辑/etc/resolv.conf 文件，增加一行dns地址，例如：nameserver 8.8.4.4
类似这种：

解决方法二：
也可直接在hosts文件里添加解析，从 dig返回的ip随便选个加进hosts文件：

[root@docker ~]# dig @114.114.114.114 index.docker.io

/etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

18.215.138.58 index.docker.io
52.1.184.176 index.docker.io
34.194.164.123 index.docker.io

然后在进行docker pull & docker search influxdb就可以了
