fleet-spawn(1) -- Run services on drones.


fleet spawn [<options>] -- [<command>...]


Execute <command> on a drone and restart the process when it dies.

Your spawned process will get the $REPO name, $COMMIT hash, $DRONE_ID, and $PROCESS_ID as environment variables from propagit.


  • drone - Specify a drone to connect to by its drone ID. You can specify '*' to spawn a command on all the drones.
  • env.<name> - Set environment variables for the commands.
  • commit - Spawn the command on a specific deployed commit. Defaults to the latest commit.
  • repo - Spawn the command under this repo name. Defaults to the closest directory name with a .git/ in it.

If you haven't set a remote with fleet remote, you'll need to specify these options:

  • hub - location of the hub as a "host:port" string
  • secret - optional passphrase to connect to the hub


Start a process on a randomly-selected drone:

$ fleet spawn -- node server.js 8888
(spawned a25d7033#edc743)

Start a process with custom environment variables:

$ fleet spawn --env.FOO=3 --env.BAR=kapow -- ./beep.js 5000
(spawned b95fc0fd#07ac33)
