无法在Docker容器中安装VI Editor / vim

Question

大家好，

我正在尝试在docker pulsar（我在docker容器中拉出pulsar映像）容器中安装vim，我的Windows机器中有docker。 我用了两个命令                        这两个命令都失败了.....

首先：apt-get更新

Err:1 http://security.debian.org/debian-security stretch/updates InRelease
Could not resolve 'security.debian.org'
Err:2 http://deb.debian.org/debian stretch InRelease
Could not resolve 'deb.debian.org'
Err:3 http://deb.debian.org/debian stretch-updates InRelease
Could not resolve 'deb.debian.org'
Reading package lists... Done
W: Failed to fetch http://deb.debian.org/debian/dists/stretch/InRelease  
Could not resolve 'deb.debian.org'
W: Failed to fetch http://deb.debian.org/debian/dists/stretch- 
updates/InRelease  Could not resolve 'deb.debian.org'
W: Failed to fetch http://security.debian.org/debian- 
security/dists/stretch/updates/InRelease  Could not resolve ' 
'security.debian.org'
W: Some index files failed to download. They have been ignored, or old ones 
used instead.

第二次：apt-get install vim

libgpm2 vim vim-common vim-runtime xxd

您的DNS存在问题。我敢肯定，如果您这样做：

$ ping deb.debian.org

您还将收到一个错误。
