Gaudi: graphically manage your docker architecture

6 June 2014 in Docker, Hi-Tech

Luc (@lstep) informed me about an interesting software that looks like Juju at first and I wanted to share it with you. It’s called Gaudi. If you already use Docker to setup your dev box for large applications, don’t you suffer to maintain complex Dockerfiles? Splitting a service Oriented Architecture into several Docker containers is the solution, except managing links and mounts between them is a pain. gaudi solves that by offering a way to describe a system of Docker containers using a simple DSL.

Ceph: cluster GUI is now OpenSource!!! Thanks RedHat

4 June 2014 in Ceph, Hi-Tech

This is a very good news if you’re using Ceph in production! Originally delivered as a proprietary dashboard included with Inktank Ceph Enterprise, Calamari has some really great visualization stuff for your cluster as well as the long term goal of being the all-in-wonder management system that can configure and analyze a Ceph cluster. Calamari is composed in 2 elements: Backend: the Calamari backend is written in Python 2.6+, using Saltstack, ZeroRPC, gevent, Django, django-rest-framework, graphite, (and a few others I may have forgotten) and instantiates a new REST API for integration with other systems.

CoreOS: minimize your bare metal usage

29 May 2014 in Docker, Hi-Tech, Virtualization

CoreOS is a new Linux distribution that has been rearchitected to provide features needed to run modern infrastructure stacks. The strategies and architectures that influence CoreOS allow companies like Google, Facebook and Twitter to run their services at scale with high resilience. We’ve implemented them correctly so you don’t have to endure the slow, learn-as-you-go infrastructure building process. CoreOS can run on your existing hardware or on most cloud providers.

Docker: only 10 min to play with basics

27 May 2014 in Debian, Docker, Hi-Tech, Linux, LXC, Virtualization

I’ve heard of Docker a year ago, started to play with it for some months and really start using it a few days ago. At first, I thought it was more complex than expected and finally I saw how simple it is and how many time I’ve lost because I didn’t used it. Docker is an open-source engine that automates the deployment of any application as a lightweight, portable, self-sufficient container that will run virtually anywhere.
