Hi, this what I looked for so thank you very much:) But unfortunately I have an issue:
Mátyás Kőne

The region parameter must be the same that the one from the created Registry. In the post I used as an example in all commands the region us-central1. Probably this is the cause of the error.

mos gcp-iot-setup --gcp-project YOUR_PROJECT_NAME --gcp-region us-central1 --gcp-registry YOUR_REGISTRY
