Welcome to Apache Felix Karaf | |
==================================== | |
Apache Felix Karaf is a small OSGi based kernel which provides a | |
lightweight container onto which various bundles can be deployed. | |
The following features are included: | |
* Hot deployment: Karaf supports hot deployment of OSGi bundles by monitoring | |
jar files inside the [home]/deploy directory. 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 Kernel also supports exploded bundles and custom | |
deployers (a spring one is 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 the kernel and issue commands in the console | |
* Security framework based on JAAS | |
* Managing instances: Karaf provides simple commands for managing instances of Karaf. | |
You can easily create, delete, start and stop instances of Karaf through the console. | |
