Docker Machine driver for Scaleway

We just released the Docker Machine driver for Scaleway;Β You can now use Machine to create Docker hosts on Scaleway servers.

This tool comes as an alternative method of provisionning Docker engines on Scaleway and won’t replace the Docker Instant-App.

Using Docker-Machine, it is now very easy to create a Swarm cluster in minutes:Β scriptΒ (output).

It is now easy to manage a Swarm cluster of hybrid servers (x86_64 + armhf).

It is also very convenient to use a Swarm cluster composed of Raspberry PI using the Hypriot OSΒ and Scaleway servers together.


docker-diff is a mini tool to quickly compare the contents of two Docker images.

Docker + multiarch = πŸ’–

Docker + multiarch = <3

Recently, I started the multiarch organization on GitHub.

Multiarch aims to provide

1. Docker images builds of Linux distributions for multiple architecture

full list onΒ multiarch on Docker hub.

2. tools around multiarch

  • multiarch/docker-goxc: a ready-to-use goxc in Docker, build GO projects for multiple architectures from an x86_64 host
  • multiarch/true: minimalist Docker images for multiarch, ideal for testing runtime
  • multiarch/qemu-user-static: qemu-user-static Docker images for all architectures + a register special image that helps to configure the Kernel binfmt support
  • multiarch/crossbuild: multiarch cross compiling environments, cross-build C/C++ programs using Docker from an x86_64 host

3. Proof-of-concept around experimental multiarch support in Dockefile


Today, I released the first version of iocat.

iocat can be used to debug your websocket and applications from your command-line interface.

It’s an equivalent of netcat, and can act as client or server.
