==> WARNING: Server Certificates grants authority to become a
    server and access all state in the cluster including root keys
    and all ACL tokens. Do not distribute them to production hosts
    that are not server nodes. Store them as securely as CA keys.
==> Using CA file nomad-agent-ca.pem and CA key nomad-agent-ca-key.pem
==> Server Certificate saved to global-server-nomad.pem
==> Server Certificate key saved to global-server-nomad-key.pem

Create a certificate for clients:

$ nomad tls cert create -client
==> Using CA file nomad-agent-ca.pem and CA key nomad-agent-ca-key.pem
==> Client Certificate saved to global-client-nomad.pem
==> Client Certificate key saved to global-client-nomad-key.pem

Create a certificate for the CLI:

$ nomad tls cert create -cli
