If you are into open source , you just can't mis this event where thousands of likeminded people will meet.</p> <p>And if 2 days of FOSDEM madness isn't enough people organise events around it.</p> <p>Last year I organised PuppetCamp in Gent, the days before Fosdem and a MonitoringLove Hackfest in our office the 2 days after FOSDEM This year another marathon is planned.</p> <p>On Friday (31/1/2014) the CentOs community is hosting a <a href="http://wiki.centos.org/Events/Dojo/Brussels2014" rel="nofollow">Dojo in Brussels</a> at the IBM Forum. (Free, but registration required by the venue)</p> <p>After the success of PuppetCamp in Gent last year we decided to open up the discussion and get more Infrastructure as Code people involved in a <a href="http://cfgmgmtcamp.eu/" rel="nofollow">CfgMgmtCamp.eu</a> </p> <p>The keynotes for CfgMgmtCamp will include the leaders of the 3 most popular tools around , both Mark Burgess, Luke Kanies and Adam Jacob will present at the event which will take place in Gent right after Fosdem. We expect people from all the major communities including, but not limited to , Ansible, Salt, Chef, Puppet, CFengine, Rudder, Foreman and Juju (Free but registration required for catering)</p> <p>And because 3 events in one week isn't enough the RedHat Community is hosting their <a href="http://community.redhat.com/blog/2013/12/announcing-infrastructure-next/" rel="nofollow">Infrastructure.next</a> conference after CfgMgmtCamp at the same venue.

I`m into devops .. I`m also a little bit into Drupal, (blame my last name..) , so one of the frustrations I've been having with Drupal (an much other software) is the automation of deployment and upgrades of Drupal sites ... </p> <p>So for the past couple of days I've been trying to catch up to the ongoing discussion regarding the results of the <a href="http://groups.drupal.org/node/155559" rel="nofollow">configuration mgmt sprint</a> , I've been looking at it mainly from a systems point of view , being with the use of Puppet/ Chef or similar tools in mind .. I know I`m late to the discussion but hey , some people take holidays in this season :) So below you can read a bunch of my comments ... and thoughts on the topic ..</p> <p>First of all , to me JSON looks like a valid option.<br /> Initially there was the plan to wrap the JSON in a PHP header for "security" reasons, but that seems to be gone even while nobody mentioned the problems that would have been caused for external configuration management tools.<br /> When thinking about external tools that should be capable of mangling the file plenty of them support JSON but won't be able to recognize a JSON file with a weird header ( thinking e.g about Augeas (augeas.net) , I`m not talking about IDE's , GUI's etc here, I`m talking about system level tools and libraries that are designed to mangle standard files. For Augeas we could create a separate lens to manage these files , but other tools might have bigger problems with the concept.</p> <p>As <a href="http://groups.drupal.org/node/155559#comment-520134" rel="nofollow">catch</a> suggest a clean .htaccess should be capable of preventing people to access the .json files There's other methods to figure out if files have been tampered with , not sure if this even fits within Drupal (I`m thinking about reusing existing CA setups rather than having yet another security setup to manage) , </p> <p>In general to me tools such as puppet should be capable of modifying config files , and then activating that config with no human interaction required , obviously drush is a good candidate here to trigger the system after the config files have been change, but unlike some people think having to browse to a web page to confirm the changes is not an acceptable solution. Just think about having to do this on multiple environments ... manual actions are error prone.. </p> <p>Apart from that I also think the storing of the certificates should not be part of the file. What about a meta file with the appropriate checksums ? (Also if I`m using Puppet or any other tool to manage my config files then the security , preventing to tamper these files, is already covered by the configuration management tools, I do understand that people want to build Drupal in the most secure way possible, but I don't think this belongs in any web application. </p> <p>When I look at other similar discussions that wanted to provide a similar secure setup they ran into a lot of end user problems with these kind of setups, an alternative approach is to make this configurable and or plugable. The default approach should be to have it enable, but the more experienced users should have the opportunity to disable this, or replace it with another framework. Making it plugable upfront solves a lot of hassle later.</p> <p>Someone in the discussion noted :<br /> "One simple suggestion for enhancing security might be to make it possible to omit the secret key file and require the user to enter the key into the UI or drush in order to load configuration from disk."</p> <p>Requiring the user to enter a key in the UI or drush would be counterproductive in the goal one wants to achieve, the last thing you want as a requirement is manual/human interaction when automating setups. therefore a feature like this should never be implemented </p> <p>Luckily there seems to be new idea around <a href="http://groups.drupal.org/node/157379" rel="nofollow">that</a> doesn't plan on using a raped json file<br /> <cite>instead of storing the config files in a standard place, we store them in a directory that is named using a hash of your site's private key, like sites/default/config_723fd490de3fb7203c3a408abee8c0bf3c2d302392. The files in this directory would still be protected via .htaccess/web.config, but if that protection failed then the files would still be essentially impossible to find. This means we could store pure, native .json files everywhere instead, to still bring the benefits of JSON (human editable, syntax checkable, interoperability with external configuration management tools, native + speedy encoding/decoding functions), without the confusing and controversial PHP wrapper.</cite></p> <p>Figuring out the directory name for the configs from a configuration mgmt tool then could be done by something similar to </p> <p><div class="geshifilter"><pre class="text geshifilter-text" style="font-family:monospace;"><ol><li style="font-family: monospace; font-weight: normal;"><div style="font-family: monospace; font-weight: normal; font-style: normal">cd sites/default/conf/$(ls sites/default/conf|head -1)</div></li></ol></pre></div></p> <p>In general I think the proposed setup looks acceptable , it definitely goes in the right direction of providing systems people with a way to automate the deployment of Drupal sites and applications at scale.</p> <p>I`ll be keeping a eye on both the direction they are heading into and the evolution of the code !</p> http://127.0.0.1:8080/blog/drupal-and-configuration-mgmt-were-getting-there#comments chef configuration management deployment devops drupal open source puppet Sun, 17 Jul 2011 20:39:27 +0000 Kris Buytaert 1045 at http://127.0.0.1:8080/blog The New devops Audience, Drupalistas ! http://127.0.0.1:8080/blog/new-devops-audience-drupalistas <p>When I first started out giving talks about devops , I realized that I was preaching to the choir, some Barcamps, the Keynote at Loadays , the Dutch Unix Usergroup etc .. lots of people in the audiences knew about the pains we were trying to solve, lots of them already knew some of the tools we use and lots of them already talk a lot with their developers or are part of the deveoplment teams</p> <p>With <a href="http://www.slideshare.net/jedi4ever/from-devops-to-devops-what-a-difference-one-character-makes" rel="nofollow">our</a> Devoxx talk, Patrick and I started to talk to a different audience , the Java devs , and it was great, we all learned from it.

Support not mandatory. Customers will not be required to purchase support services from Oracle as a condition to obtaining a commercial license to MySQL. </cite></p> <p>Yes we want support, but no we don't want a commercial license with it, we want support on the GPL version, which is a problem lots of Open Source vendors struggle with , some of them<br /> force people wanting to buy support to go for the commercial license.

I like the phone ..</p> <p>However there's <a href="http://laforge.gnumonks.org/weblog/2009/11/04/#20091104-android_mythbusters" rel="nofollow">lots</a> of people out there warning us that the Android isn't really an Open phone, true, lots of the software on it is proprietary, and lots of the software in the Market is cripple or pay ware. However imvho it's a step in the good direction going from a fully closed phone so something already more open...</p> <p>The Bad</p> <p>The volume button is to easy to use when in your pocket , hence putting the phone on silent by walking around is not unusable and Camera Autofocus is pretty bad .. no I'm not comparing to my EOS 400D, but to my previos Ericsson phone. the quality of the pictures is shaky and there is no way to cover the lens.</p> <p>As for the The Ugly I'd have to say Bluetooth support, hey I want to be able to browse / download my addressbook from my Phone to my Bluetooth enabled car , this is a feature I had on my previous phone, and the phone before that ..I want to be able to upload and download files over Bluetooth, works on both my previous phones , I want to be able to send phonebook entries over bluetooth .. so that's pretty much my biggest annoyancy<br /> (unless someone knows solutions for this ?) </p> <p>So when will Sony Ericsson release their Android in Europe ? I`m hoping they'd keep the features they already had on their previous phones , so I`m hoping for better camera and better bluetooth support ..</p> <p>We have come a long way for Linux to be present in our daily life , even for Joe Average, at home we watch TV using MythTV, my alarm is a Chumby, the phone in my downstairs office is a TuxScreen ...
