Full Description

A web screenshot container based on phantomjs's rasterize.js.

Based on the work of ubermuda.

Usage

Because phantomjs runs inside the container, you need to bind mount a volume to retrieve the screenshot.

The container is configured to write screenshots to /srv, so bind-mounting $PWD (or whatever directory you want to screenshot created in) to it seems like a good idea.

$ docker run ubermuda/screenshot
Usage: rasterize.js URL filename [paperwidth*paperheight|paperformat] [zoom]
paper (pdf output) examples: "5in*7.5in", "10cm*20cm", "A4", "Letter"
image (png/jpg output) examples: "1920px" entire page, window width 1920px
                                "800px*600px" window, clipped to 800x600

$ docker run -v $PWD:/srv ubermuda/screenshot http://www.google.com/ google.com.png 1920px

Authentication

This container now supports both Basic (browser) auth and simple HTML forms auth.
To use it, add --env-file=password.env to your docker run statement, and set
the (line based) environment variables for the authentication you need:

# Basic Auth settings
# BASICUSER=
# BASICPASS=

# HTML auth settings
LOGINURL=https://hub.docker.com/account/login
LOGINFORM=form-login
USERINPUT=id_username
PASSINPUT=id_password

USER=docsuser
PASS=notmyrealpassword

Test images from make run

no authentication:
