How to write an Action Plugin

1. Write a class based on mistral.actions.base.Actions :

from mistral.actions import base

class RunnerAction(base.Action):
   def __init__(self, param):
       # store the incomming params
       self.param = param

   def run(self):
       # return your results here
       return {'status': 0}

2. Publish the class in a namespace (in your setup.cfg)

[entry_points]
mistral.actions =
   example.runner = my.mistral_plugins.somefile:RunnerAction

3. Use your plugin

• Now you can call the action "example.runner"

Workflow:
  tasks:
    myaction:
      action: example.runner
      parameters:
        param: avalue_to_pass_in
