    Usage: nomad agent [options]
    
      Starts the Nomad agent and runs until an interrupt is received.
      The agent may be a client and/or server.
    
      The Nomad agent's configuration primarily comes from the config
      files used, but a subset of the options may also be passed directly
      as CLI arguments, listed below.
    
    General Options (clients and servers):
    
      -bind=<addr>
        The address the agent will bind to for all of its various network
        services. The individual services that run bind to individual
        ports on this address. Defaults to the loopback 127.0.0.1.
    
      -config=<path>
        The path to either a single config file or a directory of config
        files to use for configuring the Nomad agent. This option may be
        specified multiple times. If multiple config files are used, the
        values from each will be merged together. During merging, values
        from files found later in the list are merged over values from
        previously parsed files.
    
      -data-dir=<path>
        The data directory used to store state and other persistent data.
        On client machines this is used to house allocation data such as
        downloaded artifacts used by drivers. On server nodes, the data
        dir is also used to store the replicated log.
    
      -dc=<datacenter>
        The name of the datacenter this Nomad agent is a member of. By
        default this is set to "dc1".
    
      -log-level=<level>
        Specify the verbosity level of Nomad's logs. Valid values include
        DEBUG, INFO, and WARN, in decreasing order of verbosity. The
        default is INFO.
    
      -node=<name>
        The name of the local agent. This name is used to identify the node
        in the cluster. The name must be unique per region. The default is
        the current hostname of the machine.
    
      -region=<region>
        Name of the region the Nomad agent will be a member of. By default
        this value is set to "global".
    
      -dev
        Start the agent in development mode. This enables a pre-configured
        dual-role agent (client + server) which is useful for developing
        or testing Nomad. No other configuration is required to start the
        agent in this mode.
    
    Server Options:
    
      -server
        Enable server mode for the agent. Agents in server mode are
        clustered together and handle the additional responsibility of
        leader election, data replication, and scheduling work onto
        eligible client nodes.
    
      -bootstrap-expect=<num>
        Configures the expected number of servers nodes to wait for before
        bootstrapping the cluster. Once <num> servers have joined eachother,
        Nomad initiates the bootstrap process.
    
      -encrypt=<key>
        Provides the gossip encryption key
    
      -join=<address>
        Address of an agent to join at start time. Can be specified
        multiple times.
    
      -retry-join=<address>
        Address of an agent to join at start time with retries enabled.
        Can be specified multiple times.
    
      -retry-max=<num>
        Maximum number of join attempts. Defaults to 0, which will retry
        indefinitely.
    
      -retry-interval=<dur>
        Time to wait between join attempts.
    
      -rejoin
        Ignore a previous leave and attempts to rejoin the cluster.
    
    Client Options:
    
      -client
        Enable client mode for the agent. Client mode enables a given node to be
        evaluated for allocations. If client mode is not enabled, no work will be
        scheduled to the agent.
    
      -state-dir
        The directory used to store state and other persistent data. If not
        specified a subdirectory under the "-data-dir" will be used.
    
      -alloc-dir
        The directory used to store allocation data such as downloaded artificats as
        well as data produced by tasks. If not specified, a subdirectory under the
        "-data-dir" will be used.
    
      -servers
        A list of known server addresses to connect to given as "host:port" and
        delimited by commas.
    
      -node-class
        Mark this node as a member of a node-class. This can be used to label
        similar node types.
    
      -meta
        User specified metadata to associated with the node. Each instance of -meta
        parses a single KEY=VALUE pair. Repeat the meta flag for each key/value pair
        to be added.
    
      -network-interface
        Forces the network fingerprinter to use the specified network interface.
    
      -network-speed
        The default speed for network interfaces in MBits if the link speed can not
        be determined dynamically.
    
    Vault Options:
    
      -vault-enabled
        Whether to enable or disable Vault integration.
    
      -vault-address=<addr>
        The address to communicate with Vault. This should be provided with the http://
        or https:// prefix.
    
      -vault-token=<token>
        The Vault token used to derive tokens from Vault on behalf of clients.
        This only needs to be set on Servers. Overrides the Vault token read from
        the VAULT_TOKEN environment variable.
    
      -vault-create-from-role=<role>
        The role name to create tokens for tasks from.
    
      -vault-allow-unauthenticated
        Whether to allow jobs to be sumbitted that request Vault Tokens but do not
        authentication. The flag only applies to Servers.
    
      -vault-ca-file=<path>
        The path to a PEM-encoded CA cert file to use to verify the Vault server SSL
        certificate.
    
      -vault-ca-path=<path>
        The path to a directory of PEM-encoded CA cert files to verify the Vault server
        certificate.
    
      -vault-cert-file=<token>
        The path to the certificate for Vault communication.
    
      -vault-key-file=<addr>
        The path to the private key for Vault communication.
    
      -vault-tls-skip-verify=<token>
        Enables or disables SSL certificate verification.
    
      -vault-tls-server-name=<token>
        Used to set the SNI host when connecting over TLS.
    
    Atlas Options:
    
      -atlas=<infrastructure>
        The Atlas infrastructure name to configure. This enables the SCADA
        client and attempts to connect Nomad to the HashiCorp Atlas service
        using the provided infrastructure name and token.
    
      -atlas-token=<token>
        The Atlas token to use when connecting to the HashiCorp Atlas
        service. This must be provided to successfully connect your Nomad
        agent to Atlas.
    
      -atlas-join
        Enable the Atlas join feature. This mode allows agents to discover
        eachother automatically using the SCADA integration features.
