Use Greengrass IPC to report state of docker component

[habjoel]

Hey there,
I am deploying a docker image that runs a python script on a fleet of Raspberry Pi's through AWS IoT Greengrass. So far, I haven't gotten the Rollback function to work properly. I have been advised in this question to use the Greengrass IPC inside my script to report that the device is healthy through setting UpdateState to RUNNING. Can anyone show me a small example of how to do this through the Python SDK? Also, do I need to report the state regularly within my script or how can I achieve that the component moves to ERRORED once an error occurs?

Thank you for your help!

Answer:
You can do that with update_state function:
update_state(*, state=None)
Perform the UpdateState operation synchronously.

Parameters:
state (str | None) – ReportedLifecycleState enum value

Return type:
UpdateStateResponse
