如何在 debian 上安装(任何东西)：Dockerfile 中的"apt 是未知指令"

Question

如何在debian上安装(任何东西):'apt is unknown instruction' in Dockerfile

如果我搜索:[如何在debian上安装wget)

我得到的文章说:

$sudo apt install wget

---

所以我尝试在Docker中这样做:

FROM debain
apt install wget

我得到这个错误

这里可能有什么问题?

需要添加RUN指令，如下所示:

FROM debian
RUN apt install wget
