Often, when installing deb packages in your Dockerfile, some packages will install tzdata as a dependency.
The tzdata installer will try to interactively prompt you for your location using
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 Geographic area:
This will stall your image build.
In order to fix that, we’ll need to make the tzdata prompt non-interactive.
The preferred method is to add
ENV DEBIAN_FRONTEND=noninteractive
before the first RUN statements in your Dockerfile.
Alternatively you can run just the apt install or apt-get install command using DEBIAN_FRONTEND=noninteractive:
RUN DEBIAN_FRONTEND=noninteractive apt install -y tzdata
This will automatically select a default configuration for tzdata.
