How to apt-get install firefox on an openjdk:11 docker base image without "no installation candidate" error?

  apt-get, docker, dockerfile

I am trying to create a docker image which includes an installed Firefox browser, using openjdk:11-slim or openjdk:11 as my base image.

This is a minimal reproducible example of my dockerfile:

FROM openjdk:11

RUN rm -rf /var/lib/apt/lists/* && 
    apt-get update && apt-get install -y --no-install-recommends firefox

Here is the output of running docker build .:

$ docker build -t testing/simpleopenjdkfirefox .

Package firefox is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'firefox' has no installation candidate
The command '/bin/sh -c rm -rf /var/lib/apt/lists/* &&     apt-get update && apt-get install -y --no-install-recommends firefox' returned a non-zero code: 100

My reasons to believe that running apt-get install firefox should be possible are:

I’ve tried using the following base images:

  • openjdk:11-slim – my desired base image for what I’m working on
  • openjdk:11 – the full de facto openjdk image, should be the default working case
  • openjdk:11-buster – to see if Debian 10 would work

Why does the apt-get install fail in the docker build, but not in the Ubuntu CLI?
Is the issue Linux OS compatibility or something else?
