As soon as Google’s blog post “Introducing Jib — build Java Docker images better” was online, all my channels went crazy about Jib. That was a bit surprising as Jib was started over one year ago but with this blog post this project rockets with more than 1000 new GitHub stars within one day. Crazy. I got a lot asked yesterday how Jib compares to fabric8io/docker-maven-plugin (d-m-p) or fabric8io/fabric8-maven-plugin which includes d-m-p. Let me try to shed some light on the differences and pro and cons of both approaches.

Yesterday a blog post Using Docker from Maven and Maven from Docker by Kostis Kapelonis was published which gives some insights on the possible relationships between Docker and Maven. The article makes some essential points really, and gives an overview for the two remaining Docker Maven plugins as well as how Codefresh recommends doing Docker multi-stage builds as the alternative. As I’m the maintainer of the fabric8io/docker-maven-plugin, I’d like to comment on this matter. I already commented on the original blog post (thanks for approving the comment), but I’m happy to repeat my arguments here again.

I’m a big fan of the Camel Java DSL for defining Camel routes with a RouteBuilder. This is super easy and slim. However, in this blog post I show you a nerdy trick how this can be done even more elegant.

As you might know, one of my Open Source babies is the one and only fabric8io/docker-maven-plugin (d-m-p). If you already use this Maven plugin, you know, that it is super powerful and flexible to configure. This flexibility comes at a price so that the configuration can become quite complicated. Now, if you only want to build Docker images with Maven, I have good news: Since 0.25.1 d-m-p supports a zero XML configuration mode, the so-called Simple Dockerfile Build mode.

Octobox is for sure one of my favourite tools in my GitHub centred developer workflow. It is incredible for GitHub notification management which allows me to ignore all the hundreds of GitHub notification emails I get daily. Octobox is a Ruby-on-Rails application and can be used as SaaS at octobox.io or installed and used separately. Running Octobox in an own account is especially appealing for privacy reasons and for advanced features which are not enabled in the hosted version (like periodic background fetching or more information per notification). This post shows how Octobox can be ported to the free “starter” tier of OpenShift Online.

Since I got my first Amazon Echo end of last year, I love it. And although, as a typical German, I’m still a bit concerned about data privacy, at the end, convenience wins (as always :). There are many things which work flawlessly, and to be honest, the most used feature for me is a simple timer. But when it comes to aggregate actions, Alexa is still quite limited. Ok, you can define your routines, but for only an insufficient set of fixed actions. What I really would love to have is to start the radio when I get up in the morning, but this is not possible at the moment. So I remembered my last years Amazon Dash button hacks and thought it would be cool to combine both, the Dash button and Alexa. And here it is, my weekend hack …..

Our Ansible Playbooks for installing Kubernetes on a Raspberry Pi Cluster have been constantly updated and are now using the awesome kubeadm. The update to Kubernetes 1.6. was a bit tricky, though.

From time to time people come to me and say: “I really would love Jolokia if only it would be RESTful”. This post tells you why.

Now that some weeks has been passed we all had time to absorb the revised Java EE 8 proposal presented at Java One. As you know, some JSRs remained, some things were added and some stuff was dropped. Java EE Management API 2.0, supposed to be a modern successor of JSR 77, is one of the three JSRs to be dropped. What does this mean for the future of Java EE management and monitoring ?

Let’s build a Raspberry Pi Cluster running Docker and Kubernetes. There has been already a handful of good recipes, however this howto is a bit different and provides some unique features.
