FROM node:11
#
# This container uses the current version of pa11y (version 5.1.0 as of this writing) but downgrades
# to pa11y-ci version 1.3.1.  Versions 2.0.0 and above are failing to load Chromium, and I have not
# been able to get this resolved other than to downgrade the pa11y command line tool version
#
# A sample docker-compose file for this container is as follows:
#
# version: '3.4'
# services:
#   pa11y:
#     image: promet/docker-pa11y-ci
#     volumes:
#        - ./config.json:/workspace/config.json
#
#
# A config.json example file is as follows (note as of this writing www.google.com fails testing,
# while the other two URLs pass):
#
# {
#	"chromeLaunchConfig": {
#        "executablePath": "/usr/bin/google-chrome-stable",
#        "ignoreHTTPSErrors": false
#    },
#    "urls": [
#        "http://pa11y.org/",
#        "http://pa11y.org/contributing",
#        "https://www.google.com"
#    ]
# }
#
# To use this command line tool, execute the following from the command line with docker-compose
# (assumes this container is set up as a service named "pa11y"):
#
# docker-compose run pa11y /bin/bash -c "pa11y-ci --config /workspace/config.json"
