dockerself is a program that creates a new Docker container, injects itself, and finally runs itself from within Docker.
For the record, I was working on pathwar (a security learning platform) and was trying to design the less-constraining way of creating new levels.
My current best idea is to inject a custom entrypoint when the platform starts a new container, instead of requiring the level developers to adapt their Dockerfile.
Additionally, to the simplicity that is added for a level developer, this pattern also has the advantage of always putting the latest version of the entrypoint, even if the image was not updated for a very long time.
We just released the Docker Machine driver for Scaleway; 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.
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 OS and Scaleway servers together.
docker-diff is a mini tool to quickly compare the contents of two Docker images.
