Sia Container Manager

About

Sia Container Manager is an independent Android tool for operating containers on your own servers. It connects directly from your device to Docker Engine, Podman, and Docker-compatible environments to check status, follow logs, watch live stats, run commands in a terminal, and take emergency action while you are away from your desk. Built with Kotlin, Jetpack Compose, and Material 3 on an MVVM architecture, it works entirely without an account.

The app is serverless by design: it talks straight to your Docker/Podman API over HTTPS or mutual TLS, or to your host over SSH. There is no Sia Makerlab server in the path — we do not relay, receive, or store your server addresses, credentials, certificates, SSH keys, logs, environment variables, or terminal input. Server details live only on your device. A built-in Demo mode lets you explore the entire interface with sample data before you connect anything real.

Container work is destructive by nature, so the app puts safety first. Nothing on your server changes just because you connect. Every change is graded by risk — starting and stopping ask for confirmation, deletes require typing a name, and critical operations such as prune, compose down, or volume removal require biometric authentication plus name confirmation. Native ads are never placed near Start / Stop / Delete buttons, because a mis-tap on mobile is a real outage.

Independence disclaimer: Sia Container Manager is an independent application and is not affiliated with, endorsed by, or sponsored by Docker, Inc., Red Hat, Inc., Synology, QNAP, or any other vendor. "Docker" is a trademark of Docker, Inc. and "Podman" is a trademark of Red Hat, Inc.; these and other marks belong to their respective owners and are used only descriptively. Compatible environments such as Synology Container Manager, QNAP Container Station, Unraid, CasaOS, and Umbrel are supported by connecting to the Docker or Podman daemon running on them — the app does not call any vendor-specific NAS management API.

Features

• Direct connections over HTTPS / HTTP API (None, TLS, mutual TLS, Bearer token, Basic, or custom header) and over SSH (password, private key with Ed25519 / RSA / ECDSA, passphrase, and jump host)
• Auto-detection of Docker Engine, Podman (rootful and rootless), and experimental nerdctl over SSH
• Multi-server dashboard with a unified summary, unhealthy containers, and top resource consumers
• Container list, filter, and sort, plus detail tabs — Overview, Stats, Logs, Processes, Terminal, Config, Ports, Mounts, Networks, Health, and Raw
• Real-time log follow with search and regex, stdout/stderr split, and save or share (up to 10,000 lines)
• Live CPU, memory, network, block I/O, and PID stats streamed on a 1 / 2 / 5-second interval
• Interactive terminal with shell auto-detection, TTY, a special-key row, and full session teardown on exit
• Images — pull with layer progress, inspect, history, tag, delete, prune, and digest-based update checks
• Compose project detection by label, with Up / Down / Pull / Restart over SSH and YAML view, edit, and validation
• Podman pods, plus volumes, networks, events, and background monitoring with status-change and recovery alerts
• Risk-graded actions — safe operations run immediately, while destructive and critical ones require confirmation, name entry, or biometric authentication
• Credentials and SSH keys encrypted at rest with the Android Keystore (AES-GCM); SSH host keys pinned by SHA-256 fingerprint; sensitive screens protected from screen capture; secrets excluded from backup and masked in logs
• Demo mode with offline sample data; no account, no cloud sync, and no Sia Makerlab server in the path
