Usage: nomad node-drain [options] <node> Toggles node draining on a specified node. It is required that either -enable or -disable is specified, but not both. The -self flag is useful to drain the local node. General Options: -address=<addr> The address of the Nomad server. Overrides the NOMAD_ADDR environment variable if set. Default = http://127.0.0.1:4646 -region=<region> The region of the Nomad servers to forward commands to. Overrides the NOMAD_REGION environment variable if set. Defaults to the Agent's local region. -no-color Disables colored command output. -ca-cert=<path> Path to a PEM encoded CA cert file to use to verify the Nomad server SSL certificate. Overrides the NOMAD_CACERT environment variable if set. -ca-path=<path> Path to a directory of PEM encoded CA cert files to verify the Nomad server SSL certificate. If both -ca-cert and -ca-path are specified, -ca-cert is used. Overrides the NOMAD_CAPATH environment variable if set. -client-cert=<path> Path to a PEM encoded client certificate for TLS authentication to the Nomad server. Must also specify -client-key. Overrides the NOMAD_CLIENT_CERT environment variable if set. -client-key=<path> Path to an unencrypted PEM encoded private key matching the client certificate from -client-cert. Overrides the NOMAD_CLIENT_KEY environment variable if set. -tls-skip-verify Do not verify TLS certificate. This is highly not recommended. Verification will also be skipped if NOMAD_SKIP_VERIFY is set. Node Drain Options: -disable Disable draining for the specified node. -enable Enable draining for the specified node. -self Query the status of the local node. -yes Automatic yes to prompts.
