Alpine Linux timezone doesn't stick if tzdata is removed

  • 772

This used to work to set the timezone. I have a container on Alpine 3.9.4 where it worked:

RUN apk add --no-cache tzdata
ENV TZ America/Chicago
RUN apk del tzdata

I'm now creating a Docker container with Alpine Linux v3.10.3, and it doesn't work anymore. A user suggested that I need to copy to /etc/localtime:

RUN apk add --no-cache tzdata
ENV TZ America/Chicago
RUN cp /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
RUN apk del tzdata

Neither of these work if tzdata is removed. However, they work if tzdata is not removed. Why is this?

  1. You can try the setup-timezone script from alpine-conf package for that scenario.
