Discovering the Public Cloud

Set up a service (i.e. headless running command) in your Administration Panel: Advanced > Services.

The ports' range 8300 to 8499, as well as the hostname services-[account].alwaysdata.net1 are reserved to those services.


  • It must runs in foreground (forbid daemon modes) and not exit2.
  • When needing to be reached from an external application, bind it to :: (IPv6 only) and a port from 8300 to 8499.
  • Log files for running services are located at $HOME/admin/logs/services/, containing services' outputs.
  • For Public Cloud users:
    • Services are executed on a distinct servers than SSH and HTTP servers.
    • Their resources use must remain fair.
  • For Catalyst infrastructure (VPS and Dedicated Servers):
    • Range port 8300 to 8499 are not accessible from the external network. You can expose them to Internet using a firewall rule.

Catalyst users can also bind on another IP than :: and listen on ports outside of the range 8300-8499, but this is not recommended as it may lead to issues during migrations.



  • Command: redis-server -h services-[account] -p 8300
  • Monitoring command: redis-cli -h services-[account] -p 8300 ping
