Volcengine Vefaas

Deploy and manage serverless applications on Volcengine veFaaS. Use when the user wants to deploy web apps, manage functions (pull code, upload and deploy), configure environment variables, inspect veFaaS projects, troubleshoot vefaas CLI/auth/framework issues, or work with veFaaS services.

volcengine-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

bash

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

Verify installation:

bash

vefaas --version

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. Check Auth: vefaas login --check to verify login status
   • If not logged in, run vefaas login --sso (opens browser, auto-completes when user authorizes - no manual input needed)
4. Deploy: vefaas deploy --newApp <name> --gatewayName $(vefaas run listgateways --first) --yes
5. Access: vefaas domains to view URLs
