Docker构建等待用户输入

Question

我正在尝试从docker的源代码构建python。我正在从这里准备依赖项¹。

$ type .Dockerfile_07_python.txt
##############
#            #
# image name #
#            #
##############
FROM ubuntu:20.04
#################
#               #
# apt-get stuff #
#               #
#################
RUN 
apt-get update -y && 
apt-get install build-essential -y && 
apt-get install gdb -y

显然，docker构建卡住了，因为它等待一些奇怪的(?)用户输入关于我的位置(??):

$ docker build --tag host --file .Dockerfile_07_python.txt .
=> [2/2] RUN apt-get update -y && apt-get install build-essential -y && apt-get install gdb -y         225.5s
=> => # questions will narrow this down by presenting a list of cities, representing

=> => # Geographic area:

¹请注意，实际的依赖列表要长得多，这是触发此行为的最小值

您可以将环境变量DEBIAN_FRONTEND设置为'noninteractive'， apt-get将不会提示您。这样的
