# Apache Karaf Profile example

## Abstract

This example shows you how to create several profiles (in a registry) and use these profiles to create custom distributions.

## Artifacts

* **karaf-profile-example-registry** is a main container for profiles (registry).
* **karaf-profile-example-dynamic** is a custom Karaf distribution where we apply profiles "on the fly".
* **karaf-profile-example-static** is a custom Karaf distribution "static", for instance, very convenient to run on Docker.

## Build

The build uses Apache Maven. Simply use:

```
mvn clean install
```

## Registry

The `karaf-profile-example-registry` module contains several profiles (with inheritance). A profile is described with a `profile.cfg` and contains
resources used in the Karaf container (cfg file, bundles, features, ...).

You can build the registry simply using:

```
mvn clean install
```

## Assembly & Distributions

### Dynamic

The `karaf-profile-example-dynamic` module uses the profile registry (using `<profileUri/>`) to create an assembly applying profiles as boot profiles:

* `karaf`
* `loanbroker-bank1`
* `loanbroker-bank2`
* `loanbroker-bank3`
* `loanbroker-broker`
* `activemq-broker`

To build the distribution, simply do:

```
mvn clean install
```

You can find the resulting distribution in the `target` folder: `karaf-profile-example-dynamic*.tar.gz`.

### Static

The `karaf-profile-example-static` module uses also the profiles to create a distribution using the same profiles, however, it uses a static approach. It's especially
designed to run a docker or a simple JVM without dynamic change of configuration.

The build the distribution, simply do:

```
mvn clean install
```

You can find the resulting distribution in the `target` folder: `karaf-profile-example-static-4.2.1-SNAPSHOT.tar.gz`.

### Profile & shell

On a running Karaf instance, you can install the `profile` feature using:

```
karaf@root()> feature:install profile
```

Then, you have new commands available in the shell, allowing you to create, edit, apply profiles.
