如何在ubuntu docker映像中静默安装r-base

Question

我需要在ubuntu：18.04 dockerimage中安装r-base。我在通过

建立图像时正在执行此操作

RUN apt-get update; apt-get install -y r-base [many other packages]

以及许多其他软件包安装。问题是，在安装过程结束时设置r-base时，它要求用户输入时区，然后输入指定时区内的city。我显然在构建容器时无法输入数据。无论如何，我如何设法安装r-base？

## Set a default user. Available via runtime flag `--user docker` 
## Add user to 'staff' group, granting them write privileges to /usr/local/lib/R/site.library
## User should also have & own a home directory (for rstudio or linked volumes to work properly). 
RUN useradd docker \
    && mkdir /home/docker \
    && chown docker:docker /home/docker \
    && addgroup docker staff

RUN apt-get update \
    && apt-get install -y --no-install-recommends \

## Configure default locale, see https://github.com/rocker-org/rocker/issues/19
RUN echo "en_US.UTF-8 UTF-8" >> /etc/locale.gen \
    && locale-gen en_US.utf8 \

ENV LC_ALL en_US.UTF-8

## This was not needed before but we need it now
ENV DEBIAN_FRONTEND noninteractive

# Now install R and littler, and create a link for littler in /usr/local/bin
# Default CRAN repo is now set by R itself, and littler knows about it too
# r-cran-docopt is not currently in c2d4u so we install from source
