Two Nordic DevOps heavyweights join forces - Eficode and Praqma
We will shape the future of DevOps together
Your repositories are cluttered, you’re storing irrelevant builds, and your disks are full. Luckily, you’ve come to the right place for advice. Here’s how to set up automatic cleanup.

In distributed architectures networking is usually taken as a given. However, when it does not function as we expect it is often hard to understand the reason. This blog post outlines some general insights into networking with more specific techniques for understanding the networking infrastructure of a Kubernetes cluster.

Simply aligning your IT capability with your business goals isn’t enough to grow your company. To achieve real IT-enabled growth you’ll need to build on a foundation of technical excellence and thanks to DORA that’s something you can now actually measure.

Why a new software process won’t fix your delivery effectiveness
When you inherit difficult code it can take weeks to become productive. Having the right tools for the job and knowing how to use them makes a huge difference. In this post I explain how.
Advanced Testing & Refactoring Techniques
Approvals and Mutation Testing
Choosing the right tools for your critical infrastructure is a daunting task. To help you make an informed choice on binary repository management systems we took it upon ourselves to explore three leading solutions. So, how do Artifactory, Nexus and ProGet stack up?

Consultants are valued for their expertise and the fact that they’re outsiders. In this post I’ll argue that the single most valuable skill a consultant can bring to the table is to break the mental barriers in the client’s organization.

Job DSL or scripted/declarative pipelines are becoming the standard when it comes to defining jobs in Jenkins. Now we need a similar solution to maintain Jenkins itself.

Continuous Integration and Code Review are strongly correlated with success. Many use Pull Requests for code review, but for co-located teams this can be an obstacle for CI. Is there a better way?
How can Teams Collaborate without Pull Requests?
A short story about Pre-tested Integration
A developer that pushes their changes and goes on a celebratory walk to the water cooler is done. But, they’re not done done, their changes have yet to be thoroughly tested, added to future release notes, properly peer reviewed and more. These are pains we want to rid the software industry of, and here’s how we do it.

Splitting dependencies is the holy grail in software. Breaking up a monolith into reusable components and services changes everything, including approaches to version control

The life of a consultant has drawn me back, but perhaps surprisingly, this time it’s not a return to my one-person firm.
Technical Coach with Praqma
High hopes this will be my most fun job yet
A challenge we face in Praqma is finding the very right people for the job, and we know our customers are on the same difficult mission. So we aim to make the software developers of tomorrow even better.

Anyone who has worked with Docker containers, or any container technology for that matter, has at some point considered using them in production, simply because of their ease of use. And then, as you take these first steps to a containerized production, quite a few problems arise.

Praqma is at the spot (called the Egg) in Brussels, when GitHub invites Gitters and geeks from all of Europe to come together in 2 full days, where the entire world turns around just Git. We will be blogging from the scene for the next two days.

Traefik is a reverse proxy and is especially useful when running containers. In this blogpost, we will look at how we can proxy a Jenkins container running on a Docker host through Traefik and how we then can deploy an Artifactory container as well, on the same port, but on another subdomain.

VMware vSphere is widely used for virtualization in the enterprise. Thus you may face the task of managing infrastructure on this platform and of course this should be done as code. This post will give you a jumpstart into scripting the vSphere API.

Praqma’s conference finale for 2016 was CoDe Conf in Stockholm. 150 attendees made the event full to the brim, listened hard, asked great questions, and left us ready for 2017.

Just pulling a Docker image from the Docker Hub is like pulling an arbitrary binary blob from somewhere, and without really knowing what’s in it, execute it, and hope for the best!

Can you really trust your Docker images?
This is the bloody but ultimately edifying tale about “The Bonnie Situation”; I use this story as a metaphor for what consultancy is all about - solving problems. You’ll be introduced to Mr. Wolf - ‘Winston’ for those on first name terms - and you will see why we consider him a role model for any consultant.

Dockerizing different environments is becoming more and more popular. We got the idea to make an environment that would allow us to build Android aosp for any target in a Docker container. As a foundation, we decide to build Android Marshmallow (6.0.1) for Nexus9.
