在microsoft/dotnet:2.0.0-sdk中安装vim编辑器

在Docker中安装了dotnetcore 2.0.0 的sdk，没有发现可用的编辑器，该sdk是基于debian:stretch构建的，以前没玩过debian，因为CentOS玩的多一些所以对vim熟一些，所以继续入vim的坑，但是根据搜到的结果执行update-alternatives --config editor没有任何内容，执行apt-get install vim同样无效。

可以先执行apt-get update然后执行apt-get upgrade，然后再去执行apt-get install vim就可以了。
