Services

You can register services: They are custom programs running in a headless mode (i.e. without any user interaction).

Those services are declared in the administration panel’s Advanced > Services.

The service is considered functional when the command does not stop and runs in the foreground.

When you need to join your service from an external application, you must pick a port in the 8300 and 8499 range, and attach your service on :: (IPv6 only). Your service will be reachable on this port at the address services-[account].alwaysdata.net:[PORT]¹.

Unlike a command launched by-hand trough SSH, those services will be restarted automatically by the system when the service stops.

The optional Monitoring command allows you to specify a command used to check the service’s status. When this command returns an error code, the service is restarted. E.g. you can ping the service on the assigned port (i.e. 8300):

$ nc -z services-[account].alwaysdata.net 8300
