Settings
startup
Chooses whether this process starts serving immediately or waits for a separate system to activate it.
- Default:
"Active"
- Type: choice:
Active, Standby
Example
"Active" starts normal initialization. "Standby" waits for promotion before opening the service databases, so an external coordinator can decide which controller becomes active.
control_listen
Opens a separate address for health checks and commands that activate or drain this process.
- Default: Unset
- Type: string; optional
Example
"0.0.0.0:50064" lets a management system reach /readyz on port 50064, even while the main services are still starting. It does not change the SQL or UI address.
control_token_environment
Names the environment variable that contains the token required to activate or drain the process.
- Default: Unset
- Type: string; optional
Example
Set the name to "LAMINAR_CONTROL_TOKEN" and supply a token of at least 32 bytes in that environment variable. The setting contains the variable name, not the token itself.
ownership_check_interval
Sets how often the process checks that it still owns the databases it is writing to.
- Default:
1 s
- Type: duration
Example
{ secs = 1, nanos = 0 } checks once per second. This helps a process notice when it has lost database ownership; it does not elect a new controller.
