Why does docker image DNS lookup error occur? Before we dive into resolving the issue, let’s take a look at why the DNS lookup errors keep occurring. In fact, a DNS server that is locally defined in the /etc/resolv.conf file, containers by default, use 8.8.8.8, Google’s public DNS...

但本地DNS通过/etc/resolv.conf中的文件解决，该文件具有以下默认内容：

Error response from daemon: Get "https://index.docker.io/v1/search?q=nginx&n=25": dial tcp: lookup index.docker.io: no such host 解决方法 这种情况大概率是DNS污染,我们可以通过host来绕过DNS污染的问题。 在ssh中输入 Code 1 dig @114.114.114.114 index.docker.io ...
是因为Docker在构建镜像时默认不会使用主机的DNS解析服务。解决这个问题的方法有两种: 使用--network参数:可以通过在Docker build命令中添加--network参数来指定网络模式,例如使用主机网络模式(host)可以解决DNS解析问题。命令示例:docker build --network=host。
在开发过程中,我们经常遇到各种错误和异常。其中之一是 “dial tcp: lookup index.docker.io on 192.168.100.1:53: read udp 192.168.100.2” 错误。这个错误通常是由于 DNS 解析失败引起的。DNS 解析是将域名转换为对应的 IP 地址的过程,如果 DNS 解析失败,就无法建立网络连接。

Error response from daemon: Get https:/xxxxx/: dial tcp: lookup xxxxx on 8.8.8.8:53: no such host 2. 这一看就属于DNS问题,因此需要找到linux环境下的/etc/resolv.conf vim /etc/resolv.conf 这个nameserver 8.8.8.8出现很怪.google求之。
Docker is a platform designed to help developers build, share, and run container applications. We handle the tedious setup, so you can focus on the code.
