Greengrass Core V2 - Restart component on config change

Question

Hi,

After making a change to a component's config and then deploying this via GG V2 deployment, how can I trigger the component to restart automatically so it picks up the new configuration?

Many thanks in advance

Answer

Any configuration which is interpolated into the "lifecycle" section of the recipe will cause the component to reinstall. You can achieve this by interpolating the configuration into environment variables using "setEnv" key for example. If you're using IPC to read the configuration, then ideally you would subscribe to configuration changes and reconfigure without needing to restart. https://docs.aws.amazon.com/greengrass/v2/developerguide/ipc-component-configuration.html#ipc-operation-subscribetoconfigurationupdate
