python-overseer-client

Interact with overseer workflow tasks from python

The following code will register as a runtime with the overseer scheduler and accept a matching task. Finally the wrapper reports completion or failure of the command.

export PYTHON_OVERSEER_CLIENT_PROPS="/projects1/python-overseer-client.properties"
export OVERSEER_WORKFLOW_INSTANCE_UUID="59da8818-2e88-48e0-bad4-48541a8427f8"
export OVERSEER_WORKFLOW_STEP_NAME=":work"
with-overseer-client YOUR_COMMAND_HERE

The properties file describes how to connect to the message queue(s).

overseer.context.host = localhost
overseer.context.port = 60000
overseer.context.username = shh-overseer-client-user
overseer.context.password = foo
overseer.context.timeout = 10
overseer.rx.address = jms.topic.topic.shh.overseer.rx
overseer.tx.address = jms.topic.topic.shh.overseer.tx

You can supply a comma separated list of hosts and ports to connect to reserve message queues.
