Chapter 1. Configuring the Initial Features in a Standalone Container

Abstract

If you are using a standalone container, you can change the features it automatically loads the first time it is started.

Overview

The first time you start a standalone container, the container looks in the etc/org.apache.karaf.features.cfg file to discover the feature URLs (feature repository locations) and to determine which features it will load. By default, Red Hat JBoss Fuse loads a large number of features and you may not need all of them. You may also decide you need features that are not included in the default configuration.
Warning
The features loaded by a Fabric Container are controlled by the container's profiles. Changing the values as described below will have no effect on a Fabric container.
The values in etc/org.apache.karaf.features.cfg are only used the first time the container is started. On subsequent start-ups, the container uses the contents of the InstallDir/data directory to determine what to load. If you need to adjust the features loaded into a container, you can delete the data directory, but this will also destroy any state or persistence information stored by the container.
For more on features and how they are used in Red Hat JBoss Fuse, see chapter "Deploying Features" in "Deploying into Apache Karaf".

Modifying the default installed features

By default, JBoss Fuse installs a large number of features, including some that you may not want to deploy.
You can change the initial set of installed features by editing the featuresBoot property.

Modifying the default set of feature URLs

JBoss Fuse registers a number of URLs that point to feature repositories on start-up. You can change the initial set of feature URLs by editing the featureRepositories property.
