====== Termux Server Stack ======

What an Android device can serve with Termux, Caddy, and sshd. Applies to small ARM devices in the 3-4 GB RAM range: a Retroid Pocket and a Lenovo tablet both run this stack.

===== The Baseline Stack =====

  * **Caddy** static file server on '':8080'' (''file_server'' over ''~/www'')
  * **sshd** on '':8022'' (Termux's non-root SSH port)
  * **cron + watchdog + Termux:Boot** for boot persistence
  * A Debian ''proot-distro'' container alongside for anything Termux lacks

Everything below installs with one ''pkg install'' from the Termux main repo and runs directly under Termux, so the existing watchdog can supervise it. Versions rotate; check ''pkg show <name>'' for what is current.

===== What It Can Serve =====

^ Category ^ Packages ^ Notes ^
| Web platforms | ''pocketbase'', ''gitea''/''forgejo'', ''miniflux'', ''shiori'', ''hugo''/''zola'', ''kiwix-tools'' | PocketBase is a whole backend in one binary. Miniflux needs PostgreSQL. |
| Media | ''navidrome'', ''jellyfin-server'', ''minidlna'', ''icecast'', ''mpd''+''mympd'', ''snapcast-server'', ''transmission'' | Navidrome runs ~50-100 MB. Jellyfin direct-play fine; transcoding is impractical on ARM. |
| Sync and files | ''syncthing'', ''rclone'', ''restic''+''restic-server'', ''aria2'' | Encrypted backup backends work headless. |
| Databases | ''mariadb'', ''postgresql'', ''redis''/''valkey'', ''sqlite'', ''openldap'' | MariaDB needs tuning to ~300-500 MB. No MongoDB server package. |
| Monitoring | ''uptime-kuma'', ''netdata'' | Keep netdata's retention small. |

===== What It Cannot =====

  * Anything needing Docker or systemd services: proot is not a VM
  * Heavy transcoding (Jellyfin/Plex)
  * Browser-dependent automation (no headless Chrome worth running on 3 GB)

===== Practical Notes =====

  * Termux's ''wake_lock'' matters: ''termux-wake-lock'' keeps the CPU alive with the screen off
  * Battery is a built-in UPS. Keep charge cycling between ~40-80% for longevity
  * Static files plus sshd plus cron is the practical workload; run heavier apps on an x86 box like the [[folkzone:machines:vivobook|vivobook]]
  * Control the device headless from a laptop with adb: [[hosting:hardware:android_adb|Android ADB Control]]
