Deploy cloud configurations to a Greengrass core device

Make sure that your Greengrass core device is connected to the internet. For example, try successfully navigating to a webpage.

Make sure that the Greengrass daemon is running on your core device. In your core device terminal, run the following commands to check whether the daemon is running and start it, if needed.

1. To check whether the daemon is running:

   ps aux | grep -E 'greengrass.*daemon'

   If the output contains a root entry for /greengrass/ggc/packages/1.11.6/bin/daemon, then the daemon is running.

2. To start the daemon:

   cd /greengrass/ggc/core/
   sudo ./greengrassd start

Now you're ready to deploy the Lambda function and subscription configurations to your Greengrass core device.

In the AWS IoT console navigation pane, under Manage, expand Greengrass devices, and then choose Groups (V1).

Under Greengrass groups, choose the group that you created in Module 2.

On the group configuration page, choose Deploy.

On the Lambda functions tab, in the System Lambda functions section, choose IP detector.

Choose Edit and select Automatically detect and override MQTT broker endpoints. This enables devices to automatically acquire connectivity information for the core, such as IP address, DNS, and port number. Automatic detection is recommended, but AWS IoT Greengrass also supports manually specified endpoints. You're only prompted for the discovery method the first time that the group is deployed.
