Command: operator autopilot get-config

The Autopilot operator command is used to view the current Autopilot configuration. See the Autopilot Guide for more information about Autopilot.

Usage

nomad operator autopilot get-config [options]

If ACLs are enabled, this command requires a token with the operator:read capability.

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.

The output looks like this:

$ nomad operator autopilot get-config
CleanupDeadServers = true
LastContactThreshold = 200ms
MaxTrailingLogs = 250
ServerStabilizationTime = 10s
RedundancyZoneTag = ""
DisableUpgradeMigration = false
UpgradeMigrationTag = ""

  • CleanupDeadServers - Specifies automatic removal of dead server nodes periodically and whenever a new server is added to the cluster.

  • LastContactThreshold - Specifies the maximum amount of time a server can go without contact from the leader before being considered unhealthy. Must be a duration value such as 10s.

  • MaxTrailingLogs - specifies the maximum number of log entries that a server can trail the leader by before being considered unhealthy.

  • ServerStabilizationTime - Specifies the minimum amount of time a server must be stable in the 'healthy' state before being added to the cluster. Only takes effect if all servers are running Raft protocol version 3 or higher. Must be a duration value such as 30s.

  • RedundancyZoneTag - Controls the node-meta key to use when Autopilot is separating servers into zones for redundancy. Only one server in each zone can be a voting member at one time. If left blank, this feature will be disabled.

  • DisableUpgradeMigration - Disables Autopilot's upgrade migration strategy in Nomad Enterprise of waiting until enough newer-versioned servers have been added to the cluster before promoting any of them to voters.

  • UpgradeVersionTag - Controls the node-meta key to use for version info when performing upgrade migrations. If left blank, the Nomad version will be used.
