unable to change timezone

Question

I'm trying to change the timezone of my container into "Europe/paris", I saw I had to set TZ environment variable so I did this, but it doesn't change the timezone..

here's my Dockerfile :

FROM node:latest

RUN mkdir /pind

WORKDIR /pind


ENV TZ Europe/Paris
RUN apt update && apt install tzdata -y

ENV PRODUCTION="true"

COPY ./ ./

RUN npm install

CMD npm run start

and the output of the command date in my container :

but the real time in Europe/Paris timezone is 16:21

For an alpine based image you have to install the tzdata first. (see this issue here)

RUN apk add --no-cache tzdata
ENV TZ Europe/Paris
