+## `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.

+- `non_voting_server` `(bool: false)` - is whether this server will act as
