Technical requirements

As you will be practicing various CLI commands, you’ll need to keep your Open Horizon AIO Management Hub and the registered Edge device node that we set up in the previous chapter running. It’s advised that you follow the Verifying the pre-condition section in Chapter 7 to make sure that the basic system checks out and is running.

Primarily, you must run the following five commands to verify that your system is running correctly:

• Run the following command to ensure that all environment variables have been set correctly:

  env | grep HZN

• The following command ensures the Edge Agent is running:

  hzn version

• The following command ensures the Management Hub is accessible:

  hzn exchange version

• Run the following command to ensure user credentials are valid:

  hzn exchange user list

• Finally, run the following command to ensure the Edge device node is registered:

  hzn node list
