Greengrass Hello World

Greengrass component for sending Hello World messages.

Building the project

1. Create Python virtual environment with all dependencies:

python3 -m pip install virtualenv
python3 -m virtualenv venv
source ./venv/bin/activate
# OR
./venv/Scripts/activate

pip install git+https://github.com/aws-greengrass/[email protected]

2. Build the component:

cd HelloWorld
gdk component build

3. Deploy the component:

On an instance with a Greengrass deployment containing the Greengrass CLI:

gdk component publish

This will automatically create an S3 bucket in the correct account (if needed), deploy component artifacts to it, and register the component in Greengrass ready for deployment. Note that if a bucket is created, each core device must be granted access to it. See here for more information.

Test Locally

To test the component locally, follow the build steps, then use this command instead of deploying:

cd HelloWorld
sudo /greengrass/v2/bin/greengrass-cli deployment create \
    -a ./greengrass-build/artifacts \
    -r ./greengrass-build/recipes \
    -m "com.mike.HelloWorld=1.0.0"

Project Generation

Project was initially generated from the root using:

gdk component init --template HelloWorld --language python -n HelloWorld
