fargate-cpu-picker

About

A helper library written in TypeScript to support AWS CDK development i.e. building ECS Task Definition. It will suggest the minimum/maximum CPU (vCPU) based on memory/RAM needed to run an ECS task.

Repositories

• NPM: https://www.npmjs.com/package/fargate-cpu-picker
• GitHub: https://github.com/zulhfreelancer/fargate-cpu-picker

Setup

You may need to add DOM to the lib section in your tsconfig.json file like so:

{
  "compilerOptions": {
    // code omitted for brevity
    "lib": [
      "es2018",
      "DOM"
    ],
    // code omitted for brevity...
  }
}

Usage

import { pick } from "fargate-cpu-picker";
 
// Return minimum vCPU supported for 0.5GB memory
const minCPU = pick("0.5", "min"); // 256
 
// Without second parameter, it will fallback to minimum too
const minCPU = pick("0.5"); // 256
 
// Return maximum vCPU supported for 2GB memory
const maxCPU = pick("2", "max"); // 1024
