Comment installer tzdata sur une image Docker Ubuntu?

J'ai la ligne suivante dans le Dockerfile.

RUN apt-get install -y tzdata

Lorsque je l'exécute, il demande mon avis. Après avoir fourni ma contribution, elle s'est accrochée là. Est-ce que quelqu'un sait comment résoudre ce problème?

Configuring tzdata
------------------

Please select the geographic area in which you live. Subsequent configuration
questions will narrow this down by presenting a list of cities, representing
the time zones in which they are located.

  1. Africa      4. Australia  7. Atlantic  10. Pacific  13. Etc
  2. America     5. Arctic     8. Europe    11. SystemV
  3. Antarctica  6. Asia       9. Indian    12. US

Vous devez exécuter une série de commandes:

# set noninteractive installation
export DEBIAN_FRONTEND=noninteractive
#install tzdata package
apt-get install -y tzdata
# set your timezone
ln -fs /usr/share/zoneinfo/America/New_York /etc/localtime
dpkg-reconfigure --frontend noninteractive tzdata

(commandes commençant par # sont des commentaires et vous pouvez les ignorer)

La meilleure façon est de créer un script, de le copier dans un conteneur et de l'exécuter dans Dockerfile:

ADD yourscript.sh /yourscript.sh
RUN /yourscript.sh

Définissez deux variables d'environnement dans un fichier docker-compose. L'un désactive l'invite et l'autre définit le fuseau horaire.

docker-compose.yml

version: '3.7'
services:
  timezone:
    build: .
    environment:
      - TZ=America/New_York
      - DEBIAN_FRONTEND=noninteractive

Ensuite, installez simplement tzdata dans votre image.

Dockerfile

FROM ubuntu:18.04
RUN apt-get update && apt-get install -y tzdata
# Testing command: Print the date.  It will be in the timezone set from the compose file.
CMD date

Tester:

docker-compose up
