DeckOps is a native iOS Docker Engine API client—purpose-built for iPhone/iPad, not a terminal app or Safari wrapper. Add multiple hosts (HTTP/HTTPS, TLS, optional Basic Auth), switch fast, and manage containers, images, networks, volumes, and Swarm. Standouts: Compose-style grouping, logs/stats/exec, watched-container alerts with local notifications, and a Home Screen widget. Credentials stay on-device in Keychain—DeckOps isn't a hosted service.
