Dockerize FaasJS Application

This document describes how to dockerize a FaasJS application.

File Structure

The file structure of a FaasJS application is as follows:

.
├── index.func.ts
├── faas.yaml
├── server.ts
├── Dockerfile
|── tsconfig.json
|── package.json
|── package-lock.json
  • *.func.ts: The cloud function file. In FaasJS, all cloud function files must end with .func.ts.
  • faas.yaml: The configuration file for FaasJS, which records the configuration items of cloud service providers and plugins.
  • server.ts: The entry file of the FaasJS application.
  • Dockerfile: The Dockerfile for building the FaasJS application.

Server Entry (server.ts)

The following is an example of a server.ts file for a FaasJS application:

import { Server } from '@faasjs/server'
import { fileURLToPath } from 'node:url'
import { dirname } from 'node:path'

const __filename = fileURLToPath(import.meta.url)
const __dirname = dirname(__filename)

process.env.FaasRoot = `${__dirname}/`

const server = new Server(process.env.FaasRoot, {
  port: 3000
})

server.listen()

Dockerfile

The following is an example of a Dockerfile for a FaasJS application:

FROM faasjs/node

WORKDIR /app

COPY package.json package-lock.json ./

RUN npm install --production && npm cache clean --force

COPY . .

ENV FaasEnv=production
ENV FaasMode=mono
ENV FaasLogMode=plain
ENV FaasLog=debug

EXPOSE 3000
