In the last post, I talked about how to manage Docker and VirtualBox with Vagrant. This post follows the last one, with the integration of Ansible as a provisioner. Once again, I’m using it for the Smash project. With Ansible, I made several “group_vars” files containing custom and common information related to the used environment (dev, uat, staging…). This helps to setup different kind of environment easily. Vagrant will help to build images with Ansible deployed inside.

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.

I’m currently developing a complete packaging stack based on Docker to easily make different kind of packages for several Linux distributions. This for MySecureShell project. This stack will be used to build packages in destination of upstream Linux distribution packages. But I’d like to provide a simpler and faster way to create custom repositories mainly for Debian, Ubuntu, CentOS and Fedora. In addition if packages could be automatically created when a new tag is pushed to the GitHub account, it would be perfect.

You may upgrade your Mac OS X version to Yosemite (10.10) and saw you dual boot with Linux not working anymore :-(. That’s because Apple made changes and Refind is not yet ready for it. So here is the solution to get your dual boot half back. It won’t fully work as expected, but you’ll be able to boot to Linux with Refind and Mac OS X with the alt key.

A colleague talked to me about this tool this week and I felt in love. It helps to easily navigate into your git repository. You can have a look on last log and directly in the same interface the diff of the current commit. I’ve attached one screenshot to let you see how cool it is. The are also a lot of other features but just for browsing purpose. You can’t update or make changes.

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.
