Dockerfile getting stuck while installing Apache2-CodePudding

I was trying to create a Dockerfile for installing Apache2 on an Ubuntu base image and running Apache2 automatically when the container starts. Here are the instructions I wrote in it:

FROM ubuntu

RUN apt update; \
apt install apache2 -y

EXPOSE 80

CMD [“service”, “apache2”, “start”]

But, while installing, Apache2 is asking for geographic area and time zone and Dockerfile is getting stuck. Can anyone help with this?

CodePudding user response：

Just add the environment variable DEBIAN_FRONTEND=noninteractive before the command.

FROM ubuntu

RUN apt update; \
DEBIAN_FRONTEND=noninteractive apt install apache2 -y

EXPOSE 80

CMD [“service”, “apache2”, “start”]
