As you may know, I’m using Vagrant for more than a year now with VirtualBox. Docker is a faster alternative that needs to be taken into consideration. Having the possibility to manage both of them with the same tool can be very interesting. For information, I mainly use it with VirtualBox because it’s any platform compatible and Docker because it’s perfect for a CI like Jenkins. I recently talked about my implication into the Smash project.
Fig is a fast, isolated development environments using Docker. For some features, it can be compared to Vagrant where the Dockerfike is not enough powerful to build multiple instances. For example, let’s say you want to test a new product version of a software like MediaWiki and you want to build the complete stack. So you may need to have several tools categories (depending of the usage): Web: Nginx, PHP-FPM, Varnish App Cahing: Redis Search: ElasticSearch In Vagrant you can natively build 3 VM and interconnect them without the need of additional tool.
I really like this kind of news, new versions of docker and RedHat: Docker 1.0: this is the first stable version after more than one year of development. This version is production ready and I will start using it asap. RedHat 7: this is a good news as the version 6 started to be a little bit old now. What’s new? MariaDB replace MySQL \o/ Docker integrated systemd XFS by default Kernel 3.
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.
> 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.
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.
Vagrant and Ansible are out in version 1.6! They are both bringing new super features. For Vagrant, each major versions are bringing incredible features, this time they are: Global Status and Control: Global Status shows you the status of all created Vagrant environments on your machine. Global Control lets you control any of these created environments from anywhere on your machine. You unfortunately need to have VM created under 1.
