Updates

November 20, 2023 (November 20, 2023)

Most of my updates were made to the Terraform code for deployment of an AWS IoT Core sensor. See aws-iot-core-tf/tf for the code changes. The README includes instructions on how to deploy and publish messages.

Deployment

To accomplish my goal of deploying an AWS IoT Core, I had to create the following entities:

• Policy to publish a message
• Policy to write to S3
• IAM Role for said policies
• S3 bucket
• IoT certificate for publishing
• IoT entity (thing)
• IoT topic and rule that persists to S3

After declaring my entities on aws-iot-core-tf/tf, a simple terraform apply was all that was needed to deploy all my resources to the cloud.

Testing

Following that, tests were performed to send an image via:

aws iot-data publish \\
  --topic "iot-core-topic" \\
  --cli-binary-format raw-in-base64-out \\
  --payload fileb://test/fixtures/example.png \\
  --region "us-east-1"

Said image could then be received from S3 via:

aws s3api get-object --bucket $bucket --key <key-from-previous-step> example.png
