Right now, I am sitting in the train on my way back from the DevOps Camp Compact in Nürnberg. It was a very exhausting day with two talks that I gave and a lot of information and energy that I got from it. I want to thank the organizers Tobias and Stefan, the location sponsor (my TYPO3 friends Netlogix), and the roughly 100 participants that made this such a great day. Further, I’m happy that I was finally able to join the 6th edition after I wasn’t able to attend the previous four events. …

I am a big fan of the new Jenkins Pipeline suite and enjoy defining my pipelines as code. Now, I noticed that there is even a way to make IntelliJ IDEA aware ofthe pipeline DSL syntax, which supports the developer with autocompletion and documentation. For looking up the DSL syntax, I am a frequent visitor of the Pipeline Steps Reference on jenkins.io. As I am only seldom visiting the Jenkins web interface to use the Pipeline Syntax Snippet Generator, I was a bit puzzled when I stumbled over a mysterious IntelliJ IDEA GDSL link (available for logged-in users).

Virt-Manager is a graphical user interface for libvirt, a popular toolset for managing virtual machines provided by KVM. Unfortunately, it does not work well on MacOS. The MacOS port did not work for me, as I was not able to connect to the socket on the remote host even after changing adding the socket=/var/run/libvirt/libvirt-sock parameter. The same holds for its command-line pendant virsh. So the idea to let it natively run on Linux inside a Vagrant VM came up. Running Virt-Manager in Vagrant On that path, I had to overcome the following two challenges: to run a window manager inside...…

OpenStack Heat is the orchestration project of OpenStack, which allows to describe and provision OpenStack resources based on Heat templates, similar to Amazon CloudFormation. For a research project, I recently had the requirement to assign a floating IP address to every instance of a Heat autoscaling group (ASG). Given the fact that such setup is contradictory to the common practice having a load balancer in front of an ASG, this costed me some time to figure out. …

During the last two days, I had the opportunity to participate in a meeting of a special type of TYPO3 users: German universities. Thanks to RRZN / University of Hannover, around 50 people from allover Germany met for an event called “TYPO3 an Hochschulen” to talk about various topics regaring the use of TYPO3 in universities. Besides a couple of known faces, a lot of people, who where new to me, participated and presented various kinds of topics in two parallel tracks. The type of talk varied, besides introductions to Extbase/Fluid or Git, showcases about Solr/Nutch or Shibboleth integration, also...…

I am a member of the official TYPO3 Server Administration team since the Developer Days this year. With this article I not only want to look back, but also share some insights in what we are / I am doing in this team. I have not planned this article at all, but there’s the funny thing called Twitter and after Olivier’s tweet last night, I decided to shed some light on our work. The question was: where can i find info about the actual team and its goals, roadmap and actions? So here is a short story of how I...…
