Storm Deployer
. The Storm Deployer provides a mechanism for deploying Storm Topology Jar application files on Juju deployed Storm Servers. Deployed as a
subordinate charm, applications may be subsequently upgraded across all of your Juju services/units.


The storm charm connector is a library used by the StormDeployer subordinate Juju charm that provides a Storm bolt, spout, etc. with the host, port, user, password, etc. for the services that are related to the subordinate charm.


The storm deployer is a tool to deploy topologies to a Storm cluster that was deployed via Juju.
Deployment is possible via source code or via jar. A .storm yaml file is needed with deploy configurations. An example can be seen here.

Deploying with source code requires a .stom with the format:
topology: - name: name of the topology (this should be the same as the topologyname which is used in submitTopology()) jar: jar of the topology topologyclass: full domain and class of the topology packaging: mvn package repository: the git url where the topology can be found scriptbeforepackaging: optional script to run before packaging scriptbeforedeploying: optional script to run before deployment datasources: - parameters: - {name: name1, value: value1} - {name: name2, value: value2} type: type, can my mysql/mongo/postgres/redis/kafka/etc. script: script to execute - name: another topology

Deploying with jar requires a .storm with the format:
topology: - name: WordCount jar: WordCountExample-1.0-SNAPSHOT.jar topologyclass: com.sborny.wordcountexample.WordCountTopology packaging: jar repository: release:

Deploying from a private repository requires username and password wich can be entered as credentials in the config:
juju set stormdeployer "credentials=username:password" juju set stormdeployer "deploy=[url to .storm file on github]" juju set stormdeployer "undeploy=TopologyName" Deploying a topology with starting parameters is possible by entering them after the name:
-topology -name: ExampleTopologyName Arg1 Arg2 ...
