The latest version of the client doesn’t support rotators yet, we are working on this.
Hopefully by the end of the month we will have a version that will support it, you can track any updates in Add support for accessing serial ports inside Hamlib containers (#146) · Issues · librespacefoundation / SatNOGS / satnogs-ansible · GitLab.
Until then if you want to experiment you can try the legacy setup, you can find more details in Raspberry Pi Legacy - SatNOGS Wiki
