Happy birthday Apache Karaf

Yesterday was the first birthday of Apache Karaf.

We made a conference call between all Karaf developer. It was funny to put a voice on a name 🙂

It was very interesting even if unfortunately some key players were not available such as Guillaume or Achim.

Past Year Review

First, we made a review about this past year. Jamie had prepared a very complete review:

http://icodebythesea.blogspot.com/2011/06/apache-karaf-year-one-in-review.html

We can note that the Karaf downloads increased a lot with the 2.2.0 release. It was a really expected release and it has been included in a lot of projects both open-source (ServiceMix, CXF, Camel, Geronimo, …) and enterprise (Talend, Fuse, …).

We can conclude that the Karaf visibility and adoption have quickly increase and Karaf is now a important container in the OSGi eco-system.

Karaf Future

We also share our vision about the Karaf future.

We identified the following topics:

  1. Our first focus will be the Karaf 3.0.0 release. It means that Karaf 2.1.x branch will turn in EOL (End Of Life), the Karaf 2.2.x branch will be in maintenance mode. This release will be a major release as it includes a lot of new features and enchancements.
  2. Create custom Karaf distribution is not really easy right now and some projects have to change low level configuration files. We are going to work on Karaf dsitributions and profiles, by providing tooling (such as maven plugin).
  3. Add a premium OSGi container, Karaf should provide a complete and “sexy” web console. The current web console (powered by Felix console) will be maintained and suported, but we are going to work on a new one, highly extendible (by a plugin mechanism) and supporting branding. We are going to use a modern component-oriented framework such as Wicket.
  4. We moved forward in the clustering area with Karaf Cellar sub-project. It’s clear that clustering, clouding, and farming are features expected by the enterprises. We are going to work on this topic by extending Cellar.
  5. Related to the previous topic, provisioning is a must have. Apache ACE and Apache Karaf will work together to provide an enterprise provisioning solution.
  6. Cellar was the first Karaf sub-project. Related to provisioning, Karaf Cave OBR could be a new Karaf sub-project. The purpose is to provide an OBR server implementations including advanced features (P2P, REST interface, multi-repositories, etc).

I wrote down the concall minute notes:

https://cwiki.apache.org/confluence/display/KARAF/Apache+Karaf+First+Birthday+Meeting+%282011-06-16%29

It’s clear that we should schedule this kind of concall every two or three months. It allows us to make a kind of checkpoint and drive the Karaf roadmap.

Exposing Apache Karaf configurations with Apache Arrow Flight

Image
This blog post shows how to use Apache Arrow and Arrow Flight in Apache Karaf runtime. The code base is available here: https://github.com/jbonofre/karaf-arrow . Apache Arrow ? Apache Arrow is composed by: The Arrow format (specification). Format implementations with different languages (C, Java, Go, Rust, ...). Extra subprojects like Flight, Flight SQL, ADBC, nanoarrow, ... Apache Arrow format is a in-memory columnar format, super efficient for scanning and iterating a large chunks of data. In traditional memory buffer, we focus on "row". Apache Arrow format "groups" data per column, which is much more efficient on modern CPUs/GPUs. The Apache Arrow format is basically a specification. We have several implementations for this specification: C C++ C# Go Java Python Ruby Rust As the purpose of this blog post is to show Apache Arrow in Apache Karaf, we will use Arrow Java. In addition, Apache Arrow also provides several...

Getting started with Apache Karaf Minho

Image
Apache Karaf Minho Apache Karaf Minho is a new runtime, completely created from scratch. The objectives are: super easy to use and run ligtning fast, including GraalVM support Kubernetes compliant to be easily used on the cloud helping to optimize cloud costs by supporting applications colocation providing turnkey services allowing you to create Minho applications in a minute Minho is composed by: minho-boot is the core of Minho. It contains the runtime launcher and the core services (service registry, lifecycle service, configuration service, ...). minho-* services provided additional functionnalities in the runtime. You can use these services to create your own services, it's also where you will find the services managing sepcific kind of applications, allowing colocation. minho-tooling optionally provide convenient tools to create your own runtime. It includes minho-maven-plugin for instance. In this blog post, we will take a quick tour on A...

Using Apache Karaf with Kubernetes

Image
In a previous blog post ( http://blog.nanthrax.net/?p=893 ), I introduced the “new” docker support in Karaf and the use of Karaf static distribution. This post follows the previous one by illustrating how to use Karaf docker image with a Kubernetes cluster. Preparing Karaf static docker image As in the previous blog post, we are preparing a Karaf static distribution based docker image. For this blog post, I’m using the example provided in Karaf: https://github.com/apache/karaf/tree/master/examples/karaf-docker-example/karaf-docker-example-static-dist . I’m just building the distribution as usual: karaf-docker-example-static-dist$ mvn clean install Preparing kubernetes testing cluster For this blog, I’m using a minikube installed locally. The installation is pretty simple: Download minikube from https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 Rename minikube-linux-amd64 as minikube Copy minikube in your path, for instance /us...
