Docker Crossarch builds

This repository contains the code required to build cross-architecture Docker images on a daily basis. Images are built automatically on Travis CI.

What does it do?

The build script emulates, using QEMU, all supported environments and triggers a Docker build of all Dockerfile. Then, the following tags are pushed:

• <arch>-<version>
• <arch>-latest

If the release scheme of the software is MAJOR.MINOR, these tags are also pushed:

• <arch>-<major>
• <arch>-<major>.<minor>

Plus, if the software follows semver:

• <arch>-<major>.<minor>.<patch>

Supported architectures

• amd64
• armhf

Add a new software

Of course, we appreciate contributions.

Instructions

• Fork the project
• Duplicate one of the current software folder in the repos directory. It contains:
  • A Dockerfile. It is a normal Dockerfile, except it does not have a FROM image
  • A Repofile.js. This contains a function that must return the version of the software
  • A README.md. It describes how to use your image
• Add a <yoursoftware> key to the repos/settings.json file The following settings must be set:
  • image: The base image to use. Can be alpine or ubuntu
  • versioning: The versioning scheme of the software. Can be as-is, major-minor, or semver
• Add a BUILD=<yoursoftware> job to the .travis.yml file
• Submit a PR

Notes for Dockerfile

• A fresh, up-to-date (24h or less) Alpine (edge) or Ubuntu (latest release) image is used
• The CROSSARCH_ARCH environment variable is set to the currently being built architecture
