**Balena OS version:** balenaOS 2.113.18  
**Type:** Development  
**Device:** Raspberry Pi Zero W

When I try to deploy the [Anthias project](https://github.com/Screenly/Anthias) into BalenaCloud device, I get the following error:

```auto
balena --debug push <myfleetname>

```

I tried adding the node engine version into the package.json and pushing that. It was successfull however, then the service keep restarting with the following error when I look at the device logs in the BalenaCloud:

```auto
Service exited 'main sha256:aab0d9cbf68b3665e76b801f094eece0d2a9010e91a013c129940761f692a4fa'

 main npm ERR! A complete log of this run can be found in:

```

I can’t connect to the local IP address specified in the BalenaCloud, I don’t know if that’s a separate issue.

@cyolveren, I’d like to confirm if you’re trying to deploy Anthias on your own Balena Cloud fleet.  
We haven’t added docs yet specific to deploying Anthias on a fleet. In the meantime, I’ll try to help you out on this one.

What _other_ specific commands and steps did you run and do (respectively)?

(Looking at the error, it might be that Balena is looking for a `docker-compose.yml` when running `balena push`).

Looking closely at the Anthias repo, there’s only that `docker-compose.balena.yml.tmpl` file.  
There should be a script for generating a `docker-compose.yml` file. As a temporary workaround, you can take a look at [this diff](https://github.com/Screenly/Anthias/compare/master...nicomiguelino:Anthias:balena-deploy-2). I’ve applied the changes on my forked Anthias repo, in `balena-deploy-2` branch.

I’d like to hear back from you. (How can I be of further help?) Thanks!
