is a OSGi-based runtime which provides a lightweight container onto which various components and applications can be deployed. Apache Karaf uses either Apache Felix Framework or Eclipse Equinox OSGi frameworks managed directly from a main instance (root).

By default, Apache Karaf runs with Apache Felix Framework, but karaf@root()> feature:install camel-spring karaf@root()> bundle:install -s mvn:org.apache.camel/ camel-example-osgi/2.10.1 The example installed is using Camel to start a timer every 2 seconds and output a message

It provides an OSGi Bundle Repository (OBR) and Karaf Features you to directly register a Cave repository into an OBR RepositoryAdmin OSGi service. • Artifact Upload: Users can upload OSGi bundle in a Cave repository. It supports URLs like mvn:groupId/artifactId/version able to get artifacts present on an "external" repository (local file: or remote http:), looking for OSGi bundles, and copy the artifacts in the Cave repository storage. The cave-server feature provides

REST Overview Apache Karaf Cave is an Apache Karaf sub-project. Cave is an implementation of the OSGi Repository specification, providing additional features such as a complete Maven repository support API: Cave provides a REST API to manipulate the repositories. • Artifact Upload: Users can upload OSGi bundle in a Cave repository. It supports URLs like mvn:groupId/artifactId/version, file:, http:, or remote http:), looking for OSGi bundles, and copy the artifacts in the Cave repository storage. Karaf Cave provides two components: • the cave-server is the full OSGi repository service, including
