Usage: nomad tls <subcommand> <subcommand> [options]

This command groups subcommands for creating certificates for Nomad TLS configuration.

when securing your Nomad cluster.

Some simple examples for creating certificates can be found here.
More detailed examples are available in the subcommands or the documentation.

    $ nomad tls ca create

Create a server certificate

    $ nomad tls cert create -server
