Developer Guide

Deploy Cloud Configurations to an AWS IoT Greengrass Core Device

  1. Make sure that your AWS IoT Greengrass core device is connected to the internet. (For example, see if you can successfully navigate to a webpage.)

  2. Make sure that the AWS IoT Greengrass daemon is running on your core device. Run the following commands in your core device terminal.

    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/1.9.1/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 AWS IoT Greengrass core device.

  3. In the AWS IoT Core console, on the group configuration page, from Actions, choose Deploy.

  4. On the Configure how devices discover your core page, choose Automatic detection. 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.

  5. If prompted, on the Grant permission to access other services page, choose Grant permission. This creates the Greengrass service role, which allows AWS IoT Greengrass to access other AWS services on your behalf. This role is required for deployments to succeed. You need to create a service role only once per account.

The first deployment might take a few minutes. When the deployment is complete, you should see Successfully completed in the Status column on the Deployments page:


The deployment status is also displayed below the group's name on the page header.
