When I try to 

apt-get install -y tzdata

the command line option for picking timezone shows up. I am trying to use this in a script to do some setup, how can I make the apt-get run without user input?

I know to reconfigure the tzdata I can do 

echo "America/New_York" > /etc/timezone
dpkg-reconfigure -f noninteractive tzdata

But when installing I need it to run fully even if it doesn't set the right timezone, I can always reconfigure it.

I tried 

echo 5 | apt-get install -y tzdata

but it is not working as expected.

dockerfile apt-get ubuntu bash

If someone wants to achieve it in Dockerfile, use as below.

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

To avoid playing directly with symlinks and to run configuration only once, I suggest to use debconf-set-selections command:

echo 'tzdata tzdata/Areas select Europe' | debconf-set-selections
echo 'tzdata tzdata/Zones/Europe select Paris' | debconf-set-selections
DEBIAN_FRONTEND="noninteractive" apt install -y tzdata

I have recently found the following solution in a Dockerfile building the Cingulata FHE library:

ln -snf /usr/share/zoneinfo/$(curl https://ipapi.co/timezone) /etc/localtime

It basically uses the API provided by ipapi.co to retrieve the timezone information. This automatically configures the timezone properly instead of skipping the dialog and using the default (UTC).

All credit for this should go to @PYA but the right order should be:

ln -fs /usr/share/zoneinfo/America/New_York /etc/localtime
export DEBIAN_FRONTEND=noninteractive
apt-get install -y tzdata
dpkg-reconfigure --frontend noninteractive tzdata

Here is how I did it:

echo 1 > input.txt
echo 1 >> input.txt
apt-get install -y tzdata < input.txt
ln -fs /usr/share/zoneinfo/America/Los_Angeles /etc/localtime
echo America/Los_Angeles > /etc/timezone

The first two echo statements create a text file that contains the selection numbers for the geographic area menu and the city/region menu. This file is then used to provide input to the apt-get install command. The tzdata package will be installed without asking for any user input. The timezone will be set to Africa/Abidjan as if you entered 1 and 1 in response to the prompts you would normally get. Then I change the timezone to what I want with the last two commands.

Instead of 1 and 1, you could use the actual numbers for the geographic area and city/region that you want, but it seems to me that those numbers could change.

here is what worked for me:

from ubuntu:bionic
ARG DEBIAN_FRONTEND=noninteractive
RUN apt-get update && apt-get install -y tzdata

RUN unlink /etc/localtime
RUN ln -s /usr/share/zoneinfo/America/New_York /etc/localtime
