Run applications on Balena Fin

Hi all, I am trying to do a audio recording task by connecting a microphone to Balena Fin. I am wondering how can I run my microphone with Balena Fin? I successfully pushed the microphone dockerfile to my Balena Cloud. How can I set to start my microphone to record?

Hi @Xia, what microphone Dockerfile have you pushed to your balena application? DId you use some GitHub example?
Thanks,

Hi @majorz, I wrote the microphone Dockerfile by myself. I am wondering do I run the application on the Host OS terminal on my Balena account as “balena run (image ID)”?

Here is an example application for recording audio on balena that I just found: https://github.com/janvda/balena-pulseaudio

To run balena application you need to push it first to the cloud builders with the balena CLI tool. Afterwards the application container(s) will be downloaded to the device and started by our balenaEngine that runs there. You do not have to run those images directly. You may check the getting started guide for more information on this: https://www.balena.io/docs/learn/getting-started/fincm3/python/

Thanks,
Zahari

Ok I see, I think my problem is in the Dockerfile I pushed that my microphone is not recording. But thank you for sharing the example projects
