Greengrass V2: Have component reload latest configuration settings upon new deployment.

Question

Hi,

We have a number of custom Greengrass V2 components that we'd like to automatically load in the latest set of configuration settings that may have been changed andsince  deployed to one or more devices. I'm assuming the correct way to do this is by triggering a component restart? Or is there a better way?

Accepted Answer

You can achieve this using Greengrass IPC, specifically [SubscribeToConfigurationUpdates](https://docs.aws.amazon.com/greengrass/v2/developerguide/ipc-component-configuration.html#ipc-operation-subscribetoconfigurationupdate) and [GetConfiguration](https://docs.aws.amazon.com/greengrass/v2/developerguide/ipc-component-configuration.html#ipc-operation-getconfiguration)
