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.
-
enable_redundancy_zones (bool: false) - (Enterprise-only) Controls whether
Autopilot separates servers into zones for redundancy, in conjunction with the
redundancy_zone parameter.
Only one server in each zone can be a voting member at one time.
-
disable_upgrade_migration (bool: false) - (Enterprise-only) 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.
-
enable_custom_upgrades (bool: false) - (Enterprise-only) Specifies whether to
enable using custom upgrade versions when performing migrations, in conjunction with
the upgrade_version parameter.
