Multi-arch builds of radicale!

robertbeal commented 6 years ago

This will build radicale in (currently) 4 different architectures using Travis.

build.sh generates a Dockerfile for each "arch" simply using sed to change the base image at the top of the file.
As a base image (for non amd64 builds) I've used resin's alpine images which have qemu installed
This has meant installing python3 and python3-dev as part of the build. This actually results in a smaller image (circa 40mb, as the python3-dev packages are removed once it is built which they weren't on the python:3.6.4-alpine3.7 base image)
You'll need to go into the Settings on your Travis build for radicale, and add two ENV variables, DOCKER_USER and DOCKER_PWD to allow Travis to push built images to your dockerhub account.
Variables are now set and controlled in .travis.yml, ie that's where you would upgrade the VERSION
I've cleaned up MAINTAINER in the Dockerfile as this is a deprecated tag, and replaced it with LABEL

Hi Robert, Nice work and good idea!

I just moved and lacking a reliable internet connection at @home, so I will check that in the following days.

All seems good (and working for amd64 here, not tested the other archs). Can you check my comment of build.sh?
