Want to see how your Karaf container is performing? Try the ktop command!
I've been working on a utility command for Apache Karaf based containers that will display JVM usage metrics in a manner similar to the Linux Top command. The result has been the Aetos ktop command. Aetos is Savoir Technologies' Integration Platform - essentially a custom stack of raw Apache ...

If you're not familiar with Raspberry Pi it's a small, inexpensive computer which at its heart runs a 700 MHz Low Power ARM1176JZ-F Applications ProcessorCPU with 512MB ram. My build utilizes a Debian based Linux distro, Raspbian, and an Arm compatible Oracle JDK build.

Apache Karaf 2.3.5 and 3.0.1 RCs are up for vote!!!
Apache Karaf 2.3.5 and 3.0.1 Release Candidates are both up for vote! I'll apologize that I had to switch over the Extravaganza Trapiche 2013 to a Gabbiano Chianti 2011 (Karaf 3.0.1). The former bottle accidentally made it into the general consumption collection.

Apache Karaf, your OSGi runtime environment.
Introduction
Apache Karaf is a small OSGi based runtime which provides a lightweight container onto which various components and applications can be deployed.

Here is a short list of features supported by the Karaf:

  • Hot deployment: Karaf supports hot deployment of OSGi bundles by monitoring jar files inside the [home]/deploydirectory. Each time a jar is copied in this folder, it will be installed inside the runtime. You can then update or delete it and changes will be handled automatically. In addition, the Karaf also supports exploded bundles and custom deployers (blueprint and spring ones are included by default).
  • Dynamic configuration: Services are usually configured through the ConfigurationAdmin OSGi service. Such configuration can be defined in Karaf using property files inside the [home]/etc directory. These configurations are monitored and changes on the properties files will be propagated to the services.
  • Logging System: using a centralized logging back end supported by Log4J, Karaf supports a number of different APIs (JDK 1.4, JCL, SLF4J, Avalon, Tomcat, OSGi)
  • Provisioning: Provisioning of libraries or applications can be done through a number of different ways, by which they will be downloaded locally, installed and started.
  • Native OS integration: Karaf can be integrated into your own Operating System as a service so that the lifecycle will be bound to your Operating System.
  • Extensible Shell console: Karaf features a nice text console where you can manage the services, install new applications or libraries and manage their state. This shell is easily extensible by deploying new commands dynamically along with new features or applications.
  • Remote access: use any SSH client to connect to Karaf and issue commands in the console
  • Security framework based on JAAS
  • Managing instances: Karaf provides simple commands for managing multiple instances. You can easily create, delete, start and stop instances of Karaf through the console.
  • Supports the latest OSGi 4.2 containers: Apache Felix Framework 3.0 and Eclipse Equinox 3.6
