Curiously,

```python
flyctl deploy --app <app-name> --config <config> --image <img>
==> Verifying app config
--> Verified app config
==> Building image
Searching for image 'registry.fly.io/<img>' remotely...
Error failed to fetch an image or build from source: Could not find image "registry.fly.io/<img>"

```

Couldn’t find a valid image for `--app <app-name>`. If I define the same `<app-name>` in the `<config>` file, it works fine.

Similarly,

```python
flyctl deploy --app <app-name> --config <config> --remote-only
==> Verifying app config
--> Verified app config
==> Building image
Remote builder fly-builder-<yolo> ready
==> Creating build context
--> Creating build context done

Error This operation requires the 'nomad' app platform. This app was created for the 'machines' platform.

```

Didn’t work either, as it thought (wrong) that the Fly Machine app `<app-name>` was actually a regular Fly app: [`nomad`? that’s just lame](https://community.fly.io/t/error-platform-version-mismatch-nomad-machines/4452/6) (:

Then, there’s this issue with `flyctl deploy --strategy rolling` timing out too: [Error failed to wait for VM in started state: failed to wait for machine to be ready](https://community.fly.io/t/error-failed-to-wait-for-vm-in-started-state-failed-to-wait-for-machine-to-be-ready/7230)
