June 19, 2013. One of the stumbling blocks for teamwork with Chef. Is sharing secrets; there are some files and other data that are sensitive, should not be committed to the version control repository, and the admins (or administration scripts) need them in daily work. Such files include secrets for encrypted data bags, private SSL keys,. Keys (and other access keys and passwords), or private SSH keys to log into newly created EC2 instances. Until now, I kept these in. And soon on Rubygems (I want to giv...

Of Containers, Dockers, Rockets, and Daemons. December 6, 2014. December 6, 2014. I have started using Docker. Soon after it showed up. I’ve been running dockerized services in production since well before 1.0. I am still using it quite extensively and recommend it to people. I have also recently decided to run my next project on FreeBSD. On top of that it has native ZFS. There’s just one “but”: Docker runs only on Linux, and I got used to containerized services. Jails. But it seems stalled, and porting ...

September 22, 2013. September 22, 2013. Seems to be the New Hot Thing these days. It is an application container engine it lets you pack any Linux software into a self-contained, isolated. That can be easily distributed and run on different host machines. An image is somewhere in between a well built Omnibus package. And a full-on virtual machine: it’s an LXC. Live environments that actually run the software. To conserve disk space (and RAM cache), Docker uses AUFS. It turns out we can use shared volumes...

Where does the distribution end? | Three of Coins
https://3ofcoins.net/2014/06/18/where-does-the-distribution-end
Where does the distribution end? June 18, 2014. June 18, 2014. Yesterday I’ve had an inspiring Twitter conversation with Miah Johnson. The conversation was long, branchy, and restricted by the 140 character limit. It kept me thinking. It seems the main difference we had was about where does the distribution end, and the userspace begin. I find the clunky duct tape automation and idiosyncratic distro’s solutions. Want to do stuff myself, yes, thank you, I know what I’m doing. Case in point: Python and Rub...

October 12, 2013. As I’ve used to live in Barcelona, I couldn’t pass by the opportunity to represent the dev part of 3ofcoins on the devopsdays event that took place there this week. Here are my takeaways from the dev point of view. Firstly, I’d like to thank the organizers for making this happen. I’ve done my share of conference organizing and I know how much work and stress that can be. Kudos to you guys! There were some things that could’ve gone better, but you live and learn. 8211; something few team...

Access Chef node’s attributes by JSONPath. July 21, 2013. July 22, 2013. I have just released chef-helpers 0.0.7. The gem is just a bag of helpers for Chef recipes, without any common theme. This release adds one feature that may be really useful: it overloads. To allow deep indexing with JSONPath. When is it useful? A code snippet is worth a thousand words. Clause) to take care of that:. Raises "NoMethodError: undefined method `[]' for nil:NilClass". Nil or value (most of the time). Solo require attribu...

Sunday, 17 March 2013. I've been at London 2013 DevOps Days. The last couple of days; great fun it was too. I was expecting some good presentations, but I wasn't expecting to have so many awesome chats with interesting people. Nor was I expecting a free bar that would serve me mojitos until the mint ran out, but that's another story entirely. I wrote down all the suggestions, and promised to share my notes. So here they are. Through the year, all over the world. Also throughout the year. There's enough h...
