autopilot Stanza

Placement **acl**

The autopilot stanza configures the Nomad agent to configure Autopilot behavior.

autopilot {
    cleanup_dead_servers = true
    last_contact_threshold = "200ms"
    max_trailing_logs = 250
    server_stabilization_time = "10s"
    redundancy_zone_tag = ""
    disable_upgrade_migration = true
    upgrade_version_tag = ""
}

autopilot Parameters

  • cleanup_dead_servers (bool: true) - Specifies automatic removal of dead server nodes periodically and whenever a new server is added to the cluster.

  • last_contact_threshold (string: "200ms") - 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.

  • max_trailing_logs (int: 250) specifies the maximum number of log entries that a server can trail the leader by before being considered unhealthy.

  • server_stabilization_time (string: "10s") - 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.

  • redundancy_zone_tag (string: "") - 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.

  • disable_upgrade_migration (bool: false) - 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.

  • upgrade_version_tag (string: "") - Controls the node-meta key to use for version info when performing upgrade migrations. If left blank, the Nomad version will be used.
