How to set custom REST port for apache ignite when ignite is started as a service in Opendaylight apache karaf?

Question

Opendaylight uses port 8080 which is the same as the default ignite REST http port. So i tried to change the port on which ignite listens for REST requests. Here is a java code snippet for this.

    System.setProperty("IGNITE_JETTY_PORT","7111");

    System.setProperty("IGNITE_JETTY_HOST","localhost"); 

    ignite = Ignition.start(config);

The above works fine and changes the ignite REST port when i run in eclipse. But fails when i start an ignite instance in apache karaf.

Answer 1

You can change OpenDaylight's NB REST port if that would help. See the example provided by upstream configuration management tooling like puppet-opendaylight (docs, config logic).

Answer 2

I think you may try with the configuration xml file of ignite

<property name="ConnectorConfiguration.jettyPath" value="config/ignite-rest.xml"/>

and in the ignite-rest.xml it like:

<?xml version="1.0"?>

You could change the port in the configuration file as you like,

and then start your ignite like:

ignite = Ignition.start(igniteConfigPath);
