What problem does it solve?
This Skill helps you reliably operate, upgrade, and troubleshoot a fixed Sub2API deployment on a specific Aliyun ECS server, especially when issues appear after Docker, docker-compose, proxy, Redis, or Neon Postgres related changes.
Core Features & Use Cases
- Quick operational verification: Checks container state, verifies login availability, confirms app initialization via the public settings endpoint, and reviews recent logs before proceeding.
- Controlled upgrades with rollback-friendly steps: Uses pinned image tags, backs up compose configuration, recreates the container safely, and validates outcomes afterward.
- Proxy and database issue isolation: Validates system proxy (Xray service), confirms correct proxy addressing from inside the container, and provides guided database edits using credentials from the server’s .env.
Quick Start
When you need to upgrade or debug the Sub2API service on that Aliyun server, run the Skill and follow the prescribed checks and upgrade steps in the same turn.
