example-worker

Goals:

• Show usage of the taskcluster client

• "Claim" particular tasks based on their task id and then mark them completed logging a message in stdout.

The taskcluster example worker demonstrates the API usage and workflow of a taskcluster worker. The workflow of the example worker is:

• Instantiate taskcluster queue
• Get connection string for AMQP queue
• Instantiate listener
• Instantiate QueueEvents (for controlling which events to listen for)
• Use QueueEvents to bind listener to events corresponding to pending tasks
• Create event handler for events corresponding to pending tasks
• Start listening process.
  • (Create a task -- in a production environment, a developer will submit a task-graph to the scheduler and the scheduler will create a task on the queue. To keep this worker simple, it creates a task itself).
  • Claim task
  • Report task as completed
