The mongo-kafka-stormdeployer provides a method to deploy a storm topology whenever it detect relations to MongoDB, Zookeeper and Kafka. When a relation breaks the topology will be undeployed.
The storm topology to deploy has to be located in /tmp on the machine wich hosts the stormmaster. An example of an environment:
juju deploy zookeeper juju deploy storm stormmaster juju deploy storm stormworker juju deploy mongo-kafka-stormdeployer deployer juju deploy mongodb juju deploy apache-kafka kafka juju action do kafka/0 create-topic topic=test partitions=1 replication=1 juju action fetch <id> juju add-relation zookeeper stormmaster juju add-relation zookeeper stormworker juju add-relation zookeeper kafka juju add-relation stormmaster:master stormworker:worker juju add-relation deployer stormmaster juju add-relation deployer mongodb juju add-relation deployer zookeeper juju add-relation deployer kafka
Currently only one topology will be deployed. Storm does not support multiple versions of the same topology with the same name so assure that each time the name of the topology is different. You can use a version number for instance. The deployer will not deploy the topology if it is already deployed.
