dockerfile 安装 tzdata 是无法交互问题 How to install tzdata on a ubuntu docker image?

 Q:

 

I have the following line in the Dockerfile.

RUN apt-get install -y tzdata

When I run it, it asks for my input. After I provided my input, it hung there. Does anybody know how to solve this problem?

One line only:

RUN DEBIAN_FRONTEND="noninteractive" apt-get -y install tzdata

在 dockerfile 里面添加一行

You can use ARG and ENV directives to your advantage:

 

ARG DEBIAN_FRONTEND=noninteractive
ENV TZ=Europe/Moscow
RUN apt-get install -y tzdata

 

This way DEBIAN_FRONTEND will be defined only while you build your image while TZ will persist at runtime.

在dockerfile里面添加三行
