Register edge node and deploy sample Hello World edge service

Prerequisites

• IEAM agent and hzn CLI are installed on the edge node.
• Hello World edge service has already been published into IEAM.

Steps

1. Log in to your edge node using bash with the user id ibm-workshop. Get the required helloworld node policy file.

    wget https://raw.githubusercontent.com/open-horizon/examples/master/edge/services/helloworld/horizon/node.policy.json
   

2. Export all the necessary environment variables.

    export HZN_EXCHANGE_USER_AUTH=iamapikey:<api-key-generated-in-ieam-installation>
    export HZN_EXCHANGE_URL=<ieam-management-hub-ingress>/edge-exchange/v1  # <ieam-management-hub-ingress> is same as CLUSTER_URL, exported in IEAM Installment
    export HZN_FSS_CSSURL=<ieam-management-hub-ingress>/edge-css/   # <ieam-management-hub-ingress> is same as CLUSTER_URL, exported in IEAM installation
    export HZN_ORG_ID=sandbox-edge-workshop-ieam-cluster    # This should be same organization id you created while Installing IEAM hub
   

3. Register your edge node with IEAM using helloworld policy.

    hzn register --policy node.policy.json
   

4. When the registration completes, use the following command to review the Node policy.

    hzn policy list
   

5. Validate the helloworld service container is running in docker on the edge node.

    docker ps
   

6. Unregister your edge node which will also stop the helloworld service.

    hzn unregister -Df
