Command: operator raft list-peers

The raft list-peers command is used to display the current Raft peer configuration.

See the Outage Recovery guide for some examples of how this command is used. For an API to perform these operations programmatically, please see the documentation for the Operator endpoint.

Usage

nomad operator raft list-peers [options]

If ACLs are enabled, this command requires a management token.

General Options

  • -address=<addr>: The address of the Nomad server. Overrides the NOMAD_ADDR environment variable if set. Defaults to http://127.0.0.1:4646.

  • -region=<region>: The region of the Nomad server 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. Alternatively, NOMAD_CLI_NO_COLOR may be set. This option takes precedence over -force-color.

  • -force-color: Forces colored command output. This can be used in cases where the usual terminal detection fails. Alternatively, NOMAD_CLI_FORCE_COLOR may be set. This option has no effect if -no-color is also used.

  • -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-server-name=<value>: The server name to use as the SNI host when connecting via TLS. Overrides the NOMAD_TLS_SERVER_NAME 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.

  • -token: The SecretID of an ACL token to use to authenticate API requests with. Overrides the NOMAD_TOKEN environment variable if set.

List Peers Options

  • -stale: The stale argument defaults to "false" which means the leader provides the result. If the cluster is in an outage state without a leader, you may need to set -stale to "true" to get the configuration from a non-leader server.

Examples

An example output with three servers is as follows:

$ nomad operator raft list-peers
Node                   ID               Address          State     Voter
nomad-server01.global  10.10.11.5:4647  10.10.11.5:4647  follower  true
nomad-server02.global  10.10.11.6:4647  10.10.11.6:4647  leader    true
nomad-server03.global  10.10.11.7:4647  10.10.11.7:4647  follower  true

  • Node is the node name of the server, as known to Nomad, or "(unknown)" if the node is stale and not known.

  • ID is the ID of the server. This is the same as the Address but may be upgraded to a GUID in a future version of Nomad.

  • Address is the IP:port for the server.

  • State is either "follower" or "leader" depending on the server's role in the Raft configuration.

  • Voter is "true" or "false", indicating if the server has a vote in the Raft configuration. Future versions of Nomad may add support for non-voting servers.
