在microsoft/dotnet:2.0.0-sdk中安裝vim編輯器

在Docker中安裝了dotnetcore 2.0.0 的sdk，沒有發現可用的編輯器，該sdk是基於debian:stretch構建的，以前沒玩過debian，因爲CentOS玩的多一些所以對vim熟一些，所以繼續入vim的坑，但是根據搜到的結果執行update-alternatives --config editor沒有任何內容，執行apt-get install vim同樣無效。
可以先執行apt-get update然後執行apt-get upgrade，然後再去執行apt-get install vim就可以了。
