映像生成错误期间docker repo解决错误（检查存储库文件） [英] docker repo resolving error during image build ERROR (check repositories file)

问题描述

我在构建docker映像时遇到问题，并尝试了其他DNS选项，但似乎没有运气。

I have a problem with building docker image and tried different DNS option but seems no luck.

Docker版本1.9.1，构建a34a1d5

Docker version 1.9.1, build a34a1d5

回购还活着。
为了运行容器，我使用了 docker run --dns = 192.168.1.1 -d -ti --name alpine3 alpine 标记，dns在那里工作。

Repos are alive. For running container I used docker run --dns=192.168.1.1 -d -ti --name alpine3 alpine tag and dns works weel there.

对于图像，我将DNS IP 192.168.1.1添加到了/etc/docker/daemon.json和/etc/default/docker.io以及docker eth DNS中，但这没有

For images I added my DNS IP 192.168.1.1 to /etc/docker/daemon.json and /etc/default/docker.io and to docker eth DNS but this didn't help.

然后我重新启动了docker服务多次并重新拉出了高山图像。

And I restarted docker service many times and re-pulled alpine image.

我什至在本地创建了使用本地主机进行回购，在构建过程中可以通过日志中的路径访问本地主机，我可以下载所需的文件，但是运行docker build时会收到错误。

I even created local repo with localhost which is reachable with path in the log during build, I can download needed file, but when I run docker build I receive errors.

这里是dockerfile

推荐答案

这是DNS问题，您可以使用以下步骤：

It's DNS issue you can solve it by using the following steps:

1）使用以下命令查找您的DNS IP

1) Find your DNS ip using below command

nmcli dev show | grep 'IP4.DNS'

IP4.DNS [1]：192.168.0.1

IP4.DNS[1]: 192.168.0.1

2）在桌面上创建一个文件，文件名为 deamon.json ，文件包含以下数据：
{
dns：[ 192.168.0.1， 8.8.8.8]
}

2) Create a file in the desktop which name is deamon.json and file has below data: { "dns": ["192.168.0.1", "8.8.8.8"] }

注意：将ip 192.168.0.1 替换为您的dns ip

note: replace that ip 192.168.0.1 to your dns ip

3）在系统中转到该目录 / etc / docker / 并粘贴文件 deamon.json

3) Go that directory /etc/docker/ in your system and paste file deamon.json that you just created

4）然后重新启动docker / your系统，它将解决您的问题。

4) Then restart your docker/your system, it will solve your issue.
