gghelper - AWS Greengrass helper

This is a commandline tool to assist in setting up AWS Greengrass installations.

Workflow

A typical workflow is:

1. Create a Greengrass group

   gghelper creategroup -name test
   

2. The output of the creategroup will be a tar file containing the certificates and configuration for the Greengrass Core. This should be transferred onto the GGC system and unpacked:

   tar xzf 5d7b82589d-setup.tar.gz -C /greengrass
   

3. The GGC can be started with this configuration.

   (cd /greengrass/ggc/core; sudo ./greengrassd start)
   

4. Add in a lambda function

   gghelper lambda -pinned -d dist -handler hello_vsphere.hello_vsphere_handler -name HellovSphere -role lambda-test-get -runtime python2.7
   

5. Create a subscription between the function and cloud

   gghelper createsub -source HellovSphere -target cloud -subject "hello/vsphere"
   

6. Make a deployment to download config and code to the Greengrass core

   gghelper createdeployment
   

7. Going to the Greengrass Test page, create a subscription (using # will get all the messages) to see the function run periodically every 5 seconds.
