Go to Cloud Compute and select the VM to install Node.js on. If no VM is created yet Click Here.

Get the password and public IP for the cloud user of the VM to SSH into the VM

SSH into the VM ssh cloud@"PublicIP"

Install and configure Node.js

Run sudo apt-get update to ensure repositories are up to date

Install Node.js onto the VM using sudo apt install nodejs

Verify Node.js installed using node -v

Run sudo apt install npm to be able to install dependecies

Once Node.js is installed a dependency will need to be install npm install aws-sdk

Create a Node.js script to upload a file sudo nano upload-to-a2.js

const AWS = require('aws-sdk');
const fs = require('fs');

// Configure AWS SDK with your A2 endpoint and credentials
const s3 = new AWS.S3({
  endpoint: 'YOUR_A2_ENDPOINT', // Replace with your A2 endpoint. Don't include https://
  accessKeyId: 'YOUR_ACCESS_KEY',
  secretAccessKey: 'YOUR_SECRET_KEY',
  s3ForcePathStyle: true,
  region: 'a2-west', // This doesn't need to be specific it can be anything
});

// Define the bucket name and file name
const bucketName = 'your-bucket-name';
const fileName = 'file-to-upload.txt'; // Rename or code to automatically generate names for files
const tenant = 'YOUR_TENANT_ID' ;

// Read the file
const fileContent = fs.readFileSync(fileName);

// Construct the URL with endpoint preceding the bucket name
const fileURL = `https://${s3.config.endpoint}/${tenant}:${bucketName}/${fileName}`;

// Create parameters for A2 upload
const params = {
  Bucket: bucketName,
  Key: fileName, // The name you want to give to the file in A2
  Body: fileContent,
  ACL: 'public-read', // Set to different permissions if needed
};

// Upload file to A2 Storage
s3.upload(params, (err, data) => {
  if (err) {
    console.error('Error uploading file:', err);
  } else {
    console.log('File uploaded successfully. File URL:', fileURL);
  }
});
