Docker 构建等待用户输入

Question

我正在尝试从 docker 上的源代码构建 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 构建被卡住了，因为它等待一些关于我的位置的奇怪（？）用户输入（？？）：

$ 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

¹请注意，实际的依赖项列表要长得多，这是触发此行为的最小依赖项列表

Answer 1

您可以将环境变量 DEBIAN_FRONTEND 设置为“noninteractive”，apt-get 不会提示您。像这样

##############
#            #
# image name #
#            #
##############
FROM ubuntu:20.04

#################
#               #
# apt-get stuff #
#               #
#################
RUN \
apt-get update -y && \
apt-get install build-essential -y && \
DEBIAN_FRONTEND=noninteractive apt-get install gdb -y
