Docker Timezone in Ubuntu 16.04 Image

Question

I have created a Docker container using the Ubuntu 16.04 image.

docker run -it -d --name containername -v /var/www/public --privileged ubuntu

Answer 1

Simply map the volume while running docker container

-v /etc/timezone:/etc/timezone:ro

Answer 2

Try:

echo "Asia/Kolkata" > /etc/timezone
rm -f /etc/localtime
dpkg-reconfigure -f noninteractive tzdata

You have to do rm /etc/localtime because of the Ubuntu bug.

Answer 3

Updating /etc/timezone is the usual way, but there's a bug in Xenial which means that doesn't work.

Instead you need to create a link from the desired timezone to etc/localtime:

FROM ubuntu:xenial     
RUN ln -fs /usr/share/zoneinfo/US/Pacific-New /etc/localtime && dpkg-reconfigure -f noninteractive tzdata

Answer 4

SOLVED:

FROM ubuntu:16.04

RUN apt-get update && \
    apt-get install -y software-properties-common apt-utils locales tzdata

RUN echo "tzdata tzdata/Areas select Europe" > timezone.txt
RUN echo "tzdata tzdata/Zones/Europe select Rome" >> timezone.txt
RUN debconf-set-selections timezone.txt
RUN rm /etc/timezone
RUN rm /etc/localtime
RUN dpkg-reconfigure -f noninteractive tzdata
