## Installation
Apache ActiveMQ Artemis provides features that makes it easy to install the broker on Apache Karaf (4.x or later). First you need to define the feature URL, like
```sh
karaf@root()> feature:repo-add mvn:org.apache.activemq/artemis-features/1.3.0-SNAPSHOT/xml/features
```
This will add Artemis related features
```
karaf@root()> feature:list | grep artemis
artemis | 1.3.0.SNAPSHOT | | Uninstalled | artemis-1.3.0-SNAPSHOT | Full ActiveMQ Artemis broker with default configuration
netty-core | 4.0.32.Final | | Uninstalled | artemis-1.3.0-SNAPSHOT | Netty libraries
artemis-core | 1.3.0.SNAPSHOT | | Uninstalled | artemis-1.3.0-SNAPSHOT | ActiveMQ Artemis broker libraries

## Configuration
The broker is installed as `org.apache.activemq.artemis` OSGi component, so it's configured through `${KARAF_BASE}/etc/org.apache.activemq.artemis.cfg` file. An example of the file looks like
config=file:etc/artemis.xml
name=local
domain=karaf
rolePrincipalClass=org.apache.karaf.jaas.boot.principal.RolePrincipal
| Name | Description | Default value |
| ------------------ | ----------------------------------------------- | -------------------------------------------------- |
| config | Location of the configuration file | ${KARAF_BASE}/etc/artemis.xml |
| name | Name of the broker | local |
| domain | JAAS domain to use for security | karaf |
| rolePrincipalClass | Class name used for role authorization purposes | org.apache.karaf.jaas.boot.principal.RolePrincipal |
The default broker configuration file is located in `${KARAF_BASE}/etc/artemis.xml`
