Profitable deployment of the OpcuaSimulatorStack ought to create an OPC-UA server, AWS IoT Greengrass V2 core, a corresponding AWS IoT SiteWise gateway together with asset fashions and derived belongings (representing the machines within the juice bottling line). The entire utility elements i.e., OPC-UA Server, AWS IoT Greengrass V2 core and AWS IoT SiteWise gateway are deployed in an Ubuntu EC2 Occasion created by the OpcuaSimulatorStack.

Deploying the OpcuaSimulatorStack ought to take a couple of minutes and will likely be indicated by the output of the cdk deploy command. In Step 2, we will likely be constructing a ReactJS internet utility to observe the belongings created for the juice bottling line.

Step 2: Construct a customized utility to visualise the economic bottling line operation

The cloned code repository aws-iot-app-kit-bottling-line-demo.git comprises a starter ReactJS utility within the listing named belongings/react-app. On this step, we will likely be including our AWS IoT App Package elements to the starter ReactJS utility in incremental steps.

  • Change to the ReactJS utility listing.
cd belongings/react-app
  • Set up required NPM dependencies
npm ci
  • Create a .env file within the root listing of the react-app i.e., belongings/react-app/.env
contact .env
  • Edit the .env file and add your AWS IAM credentials for programmatic entry as setting variables prefixed with REACT_APP_ as proven within the snippet. The worth for REACT_APP_AWS_SESSION_TOKEN is just required in case you are utilizing short-lived IAM credentials for programmatic entry.
REACT_APP_AWS_ACCESS_KEY_ID=<replace-with-aws-access-key-id>
REACT_APP_AWS_SECRET_ACCESS_KEY=<replace-with-aws-access-key>
