Another popular deployment option is Karaf, which is a light-weight OSGi-based JVM container. Karaf has the advantage of supporting hot code swapping, which allows you to make sure that your routes are always running. It also allows you to deploy XML-based routes (Spring or Blueprint) by simply copying the files into a $KARAF_HOME/deploy directory. If deploying camel routes to Karaf, Blueprint-based routes have some advantages over the Spring-based DSL, particularly in terms of being able to use property placeholders within your routes.
Karaf can be set up by:
- downloading Karaf from an apache.org mirror
- running ./bin/karaf to enter the shell
installing required servicesbundles (n.b. the following commands correspond to Karaf 3.x. For Karaf 2.x installations, please refer to the Karaf 2.x documentation):
Code Block language bash title Karaf console $> feature:repo-add camel 2.14.0 $> feature:repo-add activemq 5.10.0 $> feature:install camel $> feature:install activemq-camel # display available camel features $> feature:list | grep camel # install camel features, as needed $> feature:install camel-http4
setting up a service wrapper (so that karaf runs as a system-level service)
Code Block language bash title Karaf console $> feature:install wrapper $> wrapper:install
- following the directions provided by this command
