If you are automating your infrastructure using Puppet, then this blog is for you. We are glad to announce the availability of a Puppet module for ClusterControl. For those using Chef, we already published Chef cookbooks for Galera Cluster and ClusterControl some time back.
The ClusterControl module initial release is available on Puppet Forge, installing the[Read more...]
Lately there have been a lot of organisations trying to hire a devops engineer.
I myselve have been asked to fill in devops roles ..
There's a number of issues with that.
The biggest problem is that I always have to ask what exactly the organisation is looking for.
So you want a devops engineer with experience in Linux, MongoDB, MySQL and Java , does that mean you want a Java developer who is familiar with MySQL and Linux and breaths a devops Culture.
Or a Linux expert who understands Java developers and knows how to tune Mongo and MySQL ?
It's absolutely unclear what you want when you are hiring "A devops engineer"
The second problem is that you are trying to hire people who are knowledgeable about devops,
Yet a lot of those people know that you can't do devops on your own , devops is not a jobtitle. devops is not a new devops[Read more...]
A couple of us have been taking about it a lot already .. we wanted to host a one day #devops event in .be already last year.. then talks about starting a meetup group started again with @wonko_be but it was @fs111 pushing the final button and calling the rest of the .be community to order, we've set a date
and the first session will take place (agenda still needs to be detirmined)
So all you Belgian devops enthousiasts, maark October 11th in your calendar and go register here
We already have 2 other venues (Gent, Boom) lined up .. but let's get this first one started :)
Next to that here's an update for the rest of my upcoming Conference Season :
With 2 of the bigger Open Source projects I care about talking about certifications programs questions pop up again ...
Should we certify ourselves ?
So let me tell you about my experiences in getting Open Source related Certifications ..
Over a decade ago, (2001) when RedHat was still Redhat and not yet Fedora the company I was working for was about to partner with RedHat and needed to get a number of people certified for that.
So I took the challenge, I bored myselve to death during a 4 day RedHat fast track training and set out to do the exam the next day. Obviosly I scored pretty well given my yearlong experience in the subject. Back then I was told that I scored the one but European Record on the exam which was actually held by another collegue (hey Ico) , our CTO however was not amused when I told that I could have scored better but I[Read more...]
Devopsdays Mountainview sold out in a short 3 hours .. but there's other events that will breath devops this summer.
DrupalCon in Munich will be one of them ..
Some of you might have noticed that I`m cochairing the devops track for DrupalCon Munich,
The CFP is open till the 11th of this month and we are still actively looking for speakers.
We're trying to bridge the gap between drupal developers and the people that put their code to production, at scale.
But also enhancing the knowledge of infrastructure components Drupal developers depend on.
We're looking for talks both on culture (both success stories and failure) , automation,
specifically looking for people talking about drupal deployments , eg using tools like Capistrano, Chef, Puppet,
We want to hear where Continuous Integration fits in your deployment , do you do Continuous Delivery of a

Debian and Ubuntu make use of the !includedir directive at the end of the packaged my.cnf to allow for extending and overriding their default configuration without having to modify the distribution config file.
This is especially nice in combination with configuration tools like puppet as it is usually much easier to add a file to the system than to modify an existing file.
I ran into a small gotcha with this though: the default my.cnf binds mysqld to the localhost TCP interface so that it listens IP 127.0.0.1 only. To make the mysql server reachable from other hosts the bind=127.0.0.1 setting needs to be overwritten.
How to change the binding to a different IP should be obvious, but how to disable an existing binding completely if you want your mysqld to listen on all available interfaces?

I was testing some MySQL puppet modules on my Vagrant box earlier this week and one of them required augeas.
I kept running into "Could not find a default provider for augeas", however all the appropriate augeas , augeas-lib and ruby-augeas packages were installed. I inspected the different ruby directories and the files were perfectly in /usr/lib/ruby/site_ruby/1.8 where I expected them.
With all the files seemd to be in the right place, my next option was to strace a small ruby script that included augeas, guess what that showed ..
When I read on the internetz that Alex Davies was about the publish a Packt book on MySQL HA I pinged my contacts at Packt and suggested that I'd review the book .
I've ran into Alex at some UKUUG conferences before and he's got a solid background on MySQL Cluster and other HA alternatives so I was looking forward to reading the book.
Alex starts of with a couple of indepth chapters on MySQL Cluster, he does mention that it's not a fit for all problems, but I'd hoped he did it a bit more prominently ... an upfront chapter outlining the different approaches and when which approach is a match could have been better. The avid reader now might be 80 pages into MySQL cluster before he realizes it's not going to be a match[Read more...]
So about 4 monts ago there was the crazy idea to start a new FOSS event in Belgium targeted at sysadmins.
What started out as an event for local people to meet local people with some local speakers actually ended up being a small local event with some top international speakers on onfiguration mananagement and system administration mixed with a bunch of good local ones !
I had the honour to open the conference with an extremely short version of the Devops talk I gave earlier last year.. extremely short as I knew that over the course of the weekend the topic would reoccur a lot.
We had the first european talk on Chef, by Joshua Timberman, and we had Puppet talks amongst by Dan Bode from Puppetlabs and CFengine talks , devops was a frequently dropped word,[Read more...]
Last week I was in Manchester for the 2010 UKUUG Spring Conference, right .. make that 2 weeks ago , :)
The UKUUG usually hosts the more interesting conferences around ... , it's not just the schedule that attrackts me , yes there's the strong focus towards Larger Scale Unix (and mostly Linux) deployments and how to manage them, but there's also the opportunity to chat in real life with the Devops from across the chunnel.
As I was in town early I went to[Read more...]
A couple of days ago, I was helping some USG admins who were facing an interesting issue. Interesting for me, but I don’t think they’d share my views on this, as their servers were melting down under the database load.
But first let me explain the issue.
The thing is that when a client checks in to get its configuration, the puppetmaster compiles its configuration to a digestible[Read more...]
Since a long time people (including me) complained that storeconfigs was a real resource hog. Unfortunately for us, this option is so cool and useful.
Storeconfigs is a puppetmasterd option that stores the nodes actual configuration to a database. It does this by comparing the result of the last compilation against what is actually in the database, resource per resource, then parameter per parameter, and so on.
The actual implementation is based on Rails’ Active Record, which is a great way to abstract the gory details of the database, and prototype code[Read more...]
In case you haven't noticed them yet ..
MySQL Proxy has a new release and moved it's public repo to Launchpad.
(Still Launchpad isn't open source yet .. a matter of time .. but in the meanwhile Jira and Confluence are sadly gaining adoption in the market)
In the devministration area there is a new Puppet module that automagically populates puppet managed machines in Zenoss , I've seen different people using Puppet to populate their Nagios configs, but adding Zenoss to the list is new.. so when will we see the Zabbix and Hyperic plugins ?
Oh yes.. and then there is Chef
Last week I wrote about whether Google’s potential acquisitions might be stifled by its focus on its own infrastructure software projects but noted that by releasing App Engine the company was encouraging a wider ecosystem of applications based on its platform.
What I didn’t discuss at the time was the potential risk of application vendors finding themselves locked-in to the App Engine platform. Of course Amazon also has this issue, the potential impact of which was[Read more...]
If you’ve ever worked in companies with 5-10+ servers and it was your responsibility to install new boxes, change some configuration files and install new software on many boxes you definitely know how painful this work is. Every time you need to change something on 3-5-100 boxes, you go there and make those changes. Most experienced of us used some weird scripts to perform some task on many boxes or used some stuff like dsh. Even with those tricks I’d never wish this work to anyone.[Read more...]
