Running geckodriver in an Alpine docker container

Question

I\'m trying to run GeckoDriver v0.26.0 inside an Alpine 3.10 docker container, specifically python:3.6.6-alpine3.10.

After figuring some things out, I\'

Answer 1

So the root cause of the issue appears to be that Alpine uses musl libc and GeckoDriver (indirectly) uses glibc.

SGerrand has a great glibc compatibility layer package for Alpine Linux which we'll make use of.

To get GeckoDriver running on Alpine:

# Get all the prereqs
wget -q -O /etc/apk/keys/sgerrand.rsa.pub https://alpine-pkgs.sgerrand.com/sgerrand.rsa.pub
wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.30-r0/glibc-2.30-r0.apk
wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.30-r0/glibc-bin-2.30-r0.apk
apk add glibc-2.30-r0.apk
apk add glibc-bin-2.30-r0.apk

# And of course we need Firefox if we actually want to *use* GeckoDriver
apk add firefox-esr=60.9.0-r0

# Then install GeckoDriver
wget https://github.com/mozilla/geckodriver/releases/download/v0.26.0/geckodriver-v0.26.0-linux64.tar.gz
tar -zxf geckodriver-v0.26.0-linux64.tar.gz -C /usr/bin
geckodriver --version

Caveats:

• Only tested on the python:3.6.9-alpine3.10 docker image.
• Alpine 3.10 only has Firefox ESR 60. Luckily GeckoDriver v0.26 has a minimum version of FireFox 60.
  • The Alpine Edge branch has Firefox-ESR 86 and Firefox 70.
