Python

Execute some python code

Parameters

good exit codes:

What invocation process exit codes to consider as “good”. Default: 0

This only affects code in Invoke parameter

retry exit codes:

What invocation process exit codes should signal scheduler to retry the invocation as opposed to setting task into ERROR state.

This only affects code in Invoke parameter

Process:

Python code to be executed by scheduler as part of processing stage. Do not perform any heavy operations here, instead perform them in the invoke code.

You can call special function schedule() here, in that case code from Invoke parameter will be scheduled to be executed on a worker.

Invoke:

Python code to be scheduled and executed on a worker.

Use task variable to get task attributes here, e.g. task['attr'] = 123 will set attribute attr on the task to value 123. While this code will be executed on remote worker, all calls to task attribute getting methods, like task['smth'] will be resolved beforehand.

Attributes Set

Attributes set by code with something like task['attr_name'] = "something" will be set to the task
