Documented steps

  1. Authenticate. Run `fly machine clone <machine_id> -a <app>` to create a new Machine that copies the source.
  2. By default the clone gets a fresh EMPTY volume (if the source had one); restore data instead with --from-snapshot <snapshot-id> or --from-snapshot last for the most recent snapshot.
  3. Attach an existing volume with --attach-volume <volume_id>[:/path/inside/machine] instead if you want to reuse a specific volume.
  4. Control the new Machine: --name <name>, --region <region>, --vm-cpus/--vm-memory/--vm-size, and --override-cmd or --clear-cmd to set/clear the command.
  5. Create a standby for the source with --standby-for=source; use --auth for deployment monitoring.
