1. Installation

Aliyun CLI

Pre-check: Aliyun CLI >= 3.3.3 required

[MUST] Verify: aliyun version — must be >= 3.3.3.

• First install or major upgrade: /bin/bash -c "$(curl -fsSL --connect-timeout 10 --max-time 120 https://aliyuncli.alicdn.com/setup.sh)"
• Routine update (CLI >= 3.3.5): aliyun upgrade — prefer this built-in self-update over re-running the install script.
• See references/cli-installation-guide.md for full installation instructions.
