Question

I have the following docker file, and I am using the command docker build -t demo:v1 . to build the image.

FROM ubuntu:18.04
WORKDIR /app
RUN ap         


        

Answer 1

add this to your Dockerfile

ARG DEBIAN_FRONTEND=noninteractive

before installing postgresql

and I think you may want to use apt-get instead of apt to avoid this warning:

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
