Create a Greengrass Group

In an AWS Greengrass application, devices are placed into AWS Greengrass groups. An AWS Greengrass group contains information about the devices and how messages are processed in the AWS Greengrass group. Each AWS Greengrass group requires an AWS Greengrass core that processes messages sent within the group. An AWS Greengrass core needs a certificate and an AWS IoT policy to access AWS Greengrass and AWS IoT cloud services. On the Set up your Greengrass group page, choose Use easy creation.

  1. Type a name for your group, and then choose Next.

  2. Use the default name for your AWS Greengrass core, and then choose Next.

  3. Choose Create Group and Core.

  4. Click the links to download the private key, public key, and certificate for your AWS Greengrass core.

  5. Choose the CPU architecture your AWS Greengrass core will be running, and then choose Download Greengrass to download the Greengrass software package. When the download is complete, choose Finish.
