CasaOS / ZimaOS over SSH

CasaOS v2 keeps no application database. The app list in the panel is regenerated at runtime into one JSON file:

/etc/casaos/app-management.json      # 644 root, world-readable

App status, icons, titles and "is it running" all come from there. Read it before touching the panel or guessing why something looks wrong.

Step 0 — get SSH working

Nothing below works until this succeeds without a password prompt:

ssh -o BatchMode=yes -o ConnectTimeout=8 <alias> 'echo ok; id'
