Greengrass V2: Do sub-deployments inherit component versions/config from parent deployments?

Question

Hi,

We are looking at using GG subdeployments to help manage different GG deployment configurations across different groups of sensors. My question is: do subdeployments inherit deployment configs from it's parent, and overwrite these if the component is present in the subdeployment?

Alternatively, are different deployments targeting different thing groups a better approach here? If we were to go down this route, is there any way to support "inheritance" of component configs as described above?

Accepted Answer

Hi,

Subdeployments are meant to be a way to debug issues on small numbers of devices, not as a way to configure these devices as part of your usual strategy.

I'd recommend you read this article that I wrote for configuring individual devices: https://dev.to/iotbuilders/managing-per-device-configuration-with-an-aws-iot-greengrass-fleet-4obk.

Cheers,

Michael
