Support for docker - node:alpine

Issue or Feature

Hey, I'm unable to install canvas 2.8.0 on my docker container which is running node:alpine. Every time npm wants to install this package I get node-gyp error. Could someone help me out with this? Thanks.

Steps to Reproduce

Try to install node-canvas on docker container running node:alpine image

Your Environment

• Version of node-canvas : 2.8.0
• Environment: latest Node

@vdemcak how did you resolve this?

[vdemcak]

I used this. Works like a charm while being tiny.

Woah that is excellent! I'll be suggesting that to resemblejs team as a drop-in replacement...

In the meantime though I found my own solution. For posterity:

node-gfx/node-canvas-prebuilt#77 (comment)

Modify Dockerfile to include these lines somewhere before npm install --build-from-source

RUN apk add --no-cache build-base g++ cairo-dev jpeg-dev pango-dev giflib-dev

RUN apk add --update --repository http://dl-3.alpinelinux.org/alpine/edge/testing libmount ttf-dejavu ttf-droid ttf-freefont ttf-liberation ttf-ubuntu-font-family fontconfig

Yeah, I got it working in a similar way too but it increased the container size dramatically.
