Ansible Inventory 2.0 design rules

This is my third post in the Ansible Inventory series. See the first and the second posts for some background information. Preliminary note: in this post, I try to give an example of a typical deployment inventory, and what rules we might need the inventory to abide to. Whilst I tried to keep things as simple as […]

Some first design ideas for an Ansible Inventory 2.0

In a my previous post “Current state of the Ansible inventory and how it might evolve” I explained some parts of the Ansible Inventory internals, and pointed out some features I would like to improve.

Current state of the Ansible inventory and how it might evolve

This is an introductory post about the Inventory in Ansible where I’m looking at the current design and implementation, some of it internals, and where hope to yield some discussion and ideas on how it could be improved, be extended. A recent discussion at Devopsdays Ghent last week, re-spawned my interest in this topic, with some people actively […]

Packt Publishing Ansible Configuration Management review

Git and Github: keeping a feature branch updated with upstream?

Fork the project to your personal Github account, clone your fork locally, create a feature branch, make some patch, commit, push back to your personal Github account, and issue a pull request […]

Quote from Linus Torvalds: “and some kernel people tend to dismiss Ubuntu, but I really think that Ubuntu has generally had the right approach, and been very user-centric” http://techcrunch.com/2012/04/19/an-interview-with-millenium-technology-prize-finalist-linus-torvalds/

The Linux-Training Project: Linux Training v2 released

As announced in February new versions of the Linux training courses were being (re-)written by Paul. I’m pleased to announce that v2 was merged in the master branch on github. I you want to test it or just check it out: git clone git://github.com/linuxtraining/lt.git cd lt git submodule init git submodule update ./make.sh ./make.sh build […]

SSH RemoteCommand over netcat hopping, or not.

Patrick Debois‘ article on Chaining SSH tunnels inspired me to effectively start using this technique. At first my use case was pretty simple. It wasn’t the host I needed to connect to which behind a firewall, but, as it turned out, I was. I’ve got a box at home listening on a high port, as […]
