--- name: alicloud-compute-fc-serverless-devs description: Alibaba Cloud Function Compute (FC 3.0) skill for installing and using Serverless Devs to create, deploy, invoke, and remove a Python function. Use when users need CLI-based FC quick start or Serverless Devs setup guidance. version: 1.0.0 --- Category: tool # Function Compute (FC 3.0) Serverless Devs ## Goals - Install and validate Serverless Devs. - Configure credentials, initialize example project, deploy, invoke, and remove. - Provide CLI flow with Python runtime example. ## Quick Start Flow 1. Install Node.js (14+) and npm. 2. Install and validate Serverless Devs. 3. Configure credentials via guided setup. 4. Initialize example project and enter directory. 5. Deploy, invoke, and optionally remove. ## Install Serverless Devs (npm) Global install (requires sudo): ```bash sudo npm install @serverless-devs/s -g sudo s -v ``` No-sudo alternative (recommended in restricted environments): ```bash npx -y @serverless-devs/s -v ``` ## Configure Credentials (guided) ```bash sudo s config add ``` Choose `Alibaba Cloud (alibaba)`, provide `AccountID`, `AccessKeyID`, `AccessKeySecret`, and set alias. ## Configure Credentials (command) Use CLI args to configure credential alias in one command (non-interactive): ```bash s config add -a default --AccessKeyID <AK> --AccessKeySecret <SK> -f ``` If using environment variables, inject them into the command (example): ```bash s config add -a default -kl AccessKeyID,AccessKeySecret -il ${ALIBABA_CLOUD_ACCESS_KEY_ID},${ALIBABA_CLOUD_ACCESS_KEY_SECRET} -f ``` Or use Serverless Devs convention JSON environment variable (example): ```bash export default_serverless_devs_key='{\"AccountID\":\"<AccountID>\",\"AccessKeyID\":\"<AK>\",\"AccessKeySecret\":\"<SK>\"}' ``` Reference in `s.yaml`: ```yaml access: default_serverless_devs_key ``` ## Initialize Example (Python) ```bash sudo s init start-fc3-python cd start-fc3-python ``` Initialization creates `s.yaml`, `code/`, and `readme.md`; edit `code/index.py` for function logic. ## Deploy, Invoke, and Remove ```bash sudo s deploy sudo s invoke -e "test" sudo s remove ``` ## Custom Domain Binding (Avoid Default Domain Forced Download) > Note: FC default domain adds `Content-Disposition: attachment`, causing browser downloads. > Use a custom domain to avoid this behavior. ### Step 1: Configure CNAME for your domain Configure DNS CNAME to FC public CNAME: ``` <account_id>.<region_id>.fc.aliyuncs.com ``` Example (Hangzhou region): ``` 1629965279769872.cn-hangzhou.fc.aliyuncs.com ``` Note: if using apex domain (e.g. `animus.run`) and DNS provider does not support CNAME at apex, use ALIAS/ANAME records, or switch to a subdomain such as `www.animus.run`. ### Step 2: Create custom domain in Serverless Devs Option A: add `fc3-domain` resource in `s.yaml`: ```yaml resources: newsDomain: component: fc3-domain props: region: cn-hangzhou domainName: animus.run protocol: HTTP routeConfig: routes: - functionName: honnold-taipei101-news qualifier: LATEST methods: - GET - HEAD path: /* ``` `region` is example default; ask user when the best region is unclear. Then deploy: ```bash printf 'y\n' | npx -y @serverless-devs/s deploy ``` Option B: use Console (Advanced Features > Custom Domains) to create and route custom domain. ### Common Errors - `DomainNameNotResolved`: domain not resolved to correct FC CNAME. - `InvalidICPLicense`: mainland China regions require ICP filing associated with Alibaba Cloud. ## References - See `references/install_serverless_devs_and_docker.md` for detailed official steps. - HTTP trigger limitations and response header behavior (default domain enforces Content-Disposition: attachment) - https://www.alibabacloud.com/help/en/functioncompute/fc/user-guide/http-triggers-overview - Custom domain binding and CNAME guidance - https://www.alibabacloud.com/help/en/functioncompute/fc/user-guide/configure-custom-domain-names - Official source list:`references/sources.md` ## Validation ```bash mkdir -p output/alicloud-compute-fc-serverless-devs echo "validation_placeholder" > output/alicloud-compute-fc-serverless-devs/validate.txt ``` Pass criteria: command exits 0 and `output/alicloud-compute-fc-serverless-devs/validate.txt` is generated. ## Output And Evidence - Save artifacts, command outputs, and API response summaries under [REDACTED_SECRET]. - Include key parameters (region/resource id/time range) in evidence files for reproducibility. ## Prerequisites - Configure least-privilege Alibaba Cloud credentials before execution. - Prefer environment variables: `ALICLOUD_ACCESS_KEY_ID`, `ALICLOUD_ACCESS_KEY_SECRET`, optional `ALICLOUD_REGION_ID`. - If region is unclear, ask the user before running mutating operations. ## Workflow 1) Confirm user intent, region, identifiers, and whether the operation is read-only or mutating. 2) Run one minimal read-only query first to verify connectivity and permissions. 3) Execute the target operation with explicit parameters and bounded scope. 4) Verify results and save output/evidence files.
