vefaas: Volcengine FaaS CLI

vefaas is the command-line tool for Volcengine Function Service (veFaaS). It enables serverless application deployment, function management, and configuration through a streamlined workflow.

Installation

npm i -g https://vefaas-cli.tos-cn-beijing.volces.com/volcengine-vefaas-latest.tgz

> Note: The domain volces.com is Volcengine (ByteDance cloud). This tarball is the official distribution channel for the CLI — not published to npm registry. Install method matches the front matter metadata.install spec.

Verify installation:

vefaas --version

> Tip: vefaas -v (or vefaas --version) will print the current version and, if a newer release is available, show instructions on how to update. When a user encounters unsupported features or wants to check for updates, run this command first.

Core Workflow

The typical deployment pattern:

1. Check Node.js: node --version (requires >= 18, recommended 20+) - If version is too low, switch using nvm (nvm use 20) or fnm (fnm use 20), or manually install a newer version

2. Check CLI: vefaas --version to verify installation

3. Authenticate (try in order, stop at first success):

a. Auto-check (preferred): vefaas login --check — the CLI auto-detects available credentials (Ark Skill, injected tokens, etc.). If this passes, proceed to step 4. b. SSO: vefaas login --sso — if browser is available. c. AK/SK: vefaas login --accessKey --secretKey — last resort, prompt user.

4. Pre-flight check (MUST do before every deploy): vefaas inspect

- framework / language correct → don't touch start command or build settings - port wrong → fix in code (e.g., process.env.PORT || 3000), or override via --port at deploy time - Check dependency files: ensure package.json (Node.js) or requirements.txt (Python) lists all runtime deps — the server only installs what's declared, not what's globally installed locally

5. Deploy:

   # New app
   vefaas deploy --newApp  --gatewayName $(vefaas run listgateways --first) --yes
   # Existing app
   vefaas deploy --app  --yes
   

If you need to override specific parameters that inspect got wrong (port, build command, start command, etc.), pass them directly at deploy time:

   vefaas deploy \
     --newApp my-app \
     --gatewayName $(vefaas run listgateways --first) \
     --buildCommand "npm run build" \
     --outputPath dist \
     --command "node dist/index.js" \
     --port 3000 \
     --yes
   

6. Access: vefaas domains to view URLs

Quick Commands

| Purpose | Command | |---------|---------| | Check version / update | vefaas -v (shows version and update instructions if available) | | Check auth | vefaas login --check (preferred, auto-detects credentials) | | Login (SSO) | vefaas login --sso (opens browser, auto-completes) | | Login (AK/SK) | vefaas login --accessKey --secretKey (last resort) | | Init from template | vefaas init --template | | Inspect project | vefaas inspect (run before deploy to verify detection) | | Deploy new app | vefaas deploy --newApp --gatewayName $(vefaas run listgateways --first) --yes | | Deploy existing | vefaas deploy --app --yes | | List gateways | vefaas run listgateways --first | | View URLs | vefaas domains | | Set env var | vefaas env set KEY VALUE | | View config | vefaas config list | | Pull code | vefaas pull --func |

Global Options

| Option | Description | |--------|-------------| | -d, --debug | Enable debug mode for troubleshooting | | --yes | Non-interactive mode (required for CI/AI coding) | | --region | Region override (e.g., cn-beijing) |

Cookbooks

Step-by-step guides for common scenarios:

Template Quickstart — Create and deploy from official templates

Deploy Existing Code — Deploy your existing project

Deploy an Agent — Deploy a conversational AI agent as an HTTP endpoint

Publish Skill as API — Turn an OpenClaw skill into a remote service

Generate Tool Page — Generate and deploy a shareable online tool from a natural language request

Deploy Webhook — Deploy a webhook / glue function to connect two services

Manage Functions — Manage functions (pull code, upload and deploy)

Configuration — Config files and settings

Framework Detection — Supported frameworks and auto-detection

Troubleshooting — Debug mode, common issues, and solutions

Security

Declared credentials only: This skill uses VOLC_ACCESS_KEY_ID and VOLC_SECRET_ACCESS_KEY as declared in the front matter. The agent should not read or probe for any other env vars, .env files, or credential files.

Debug output: vefaas --debug may print request/response payloads that contain tokens or secrets. Do not log, store, or surface debug output to the user unless they explicitly request troubleshooting. When sharing debug output, redact any values that look like keys, tokens, or secrets.

Important Notes

Always use --yes for non-interactive mode in CI/CD and AI coding scenarios

Use $(vefaas run listgateways --first) to get an available gateway

Config is stored in .vefaas/config.json after linking

Use --debug or -d to troubleshoot issues (see Security section for caveats)

Auth: always start with vefaas login --check — the CLI auto-detects available credentials

Always run vefaas inspect before every deploy — check framework/language detection, port, and dependency files (package.json / requirements.txt). Fix issues before deploying, not after

When a feature is unsupported or you suspect the CLI is outdated, run vefaas -v to check version and see update instructions
