Apache Karaf Deployer example

Abstract

This example shows how to create a Karaf deployer.

Karaf uses deployer services on the deploy folder (using Felix FileInstall). For each file in the deploy, Karaf calls each deployer service to know:

1. If the deployer service should handle the file (based on file contain, file name, ...)
2. Actually let the deployer service deploys the file.

Build

The build uses Apache Maven. Simply use:

mvn clean install

Deployment

On a running Karaf instance, just install the deployer service using:

karaf@root()> feature:install scr
karaf@root()> bundle:install -s mvn:org.apache.karaf.examples/karaf-deployer-example/LATEST

Usage

Once deployed, you can drop any file in the deploy folder, you should see (for instance, if you dropped a file name TEST in the deploy folder):

Example deployer should install TEST

If you change the file, you should see:

Example deployer should update TEST

And if you remove the file from the deploy folder, you should see:

Example deployer should uninstall TEST
