Missing restrictions when installing packages on Alpine docker

Question

I am creating a ruby:2.3-alpine based docker image. I need to install a couple packages for my rails application to work properly. Unfortunately, the following packages do not exist in alpine repositories.

How to install them?

 $ uname -a Linux 50642453afd5 4.1.17-boot2docker #1 SMP Thu Feb 11 08:12:31 UTC 2016 x86_64 Linux $ apk add iceweasel ERROR: unsatisfiable constraints: iceweasel (missing): required by: world[iceweasel] 

Installation packages:

• libav tools
• xfonts base
• xfonts-75dpi
• Iceweasel

Answer 1

As of June 2016, "firefox-esr" is replacing Iceweasel.

Here's how to install it in an Alpine Docker container and run it to make sure it is installed correctly:

 FROM ruby:2.3-alpine RUN apk add --no-cache firefox-esr RUN firefox --version 

You will also need a virtual display (framebuffer) such as xvfb. See This for more information => https://github.com/rickypc/docker-python-firefox-xvfb/blob/master/Dockerfile
