This command is used to execute a job file in the Nomad cluster manager.

Let's break down the command:

• nomad: It is the command-line interface (CLI) for interacting with the Nomad cluster manager. This command is used to perform various operations on Nomad, such as running jobs, querying the status of jobs, etc.

• job run: This is a specific command within the nomad CLI used to run a job. A job in Nomad is a declarative configuration file that describes the desired state of a task or group of tasks to be run in the cluster.

• ${filename-nomad}: This is a placeholder indicating that the value inside the curly braces should be replaced with the actual filename of the job file you want to run. ${filename-nomad} suggests that the filename should end with .nomad as a common convention for Nomad job files.

So, when you run the command nomad job run ${filename-nomad}, make sure to replace ${filename-nomad} with the actual filename of your Nomad job file (with the extension .nomad), and the Nomad CLI will execute the job specified in that file on the Nomad cluster.
