Using Flow Object Storage with AWS S3 SDKs

Introduction
Flow Object Storage is an S3-compatible object storage service that lets you store and serve large amounts of data. 
The Flow Object Storage API is inter-operable with the AWS S3 API, meaning you can use existing S3 tools and libraries with Spaces. A common use case is managing Flow Object Storage programmatically with AWS’ S3 SDKs.
Install the SDK
Install the AWS SDK using the package manager for your language of choice.
Java Script
Go
PHP
Python
Ruby
Java Script
npm install aws-sdk
Go
go get -u github.com/aws/aws-sdk-go
PHP
php composer.phar require aws/aws-sdk-php
Python
pip install boto3
Ruby
gem install aws-sdk-s3
Obtain Access & Secret Keys
You are able to retrieve the access & secret keys in our customer portal:
https://my.flow.swiss/#/object-storage​
The examples below rely on environment variables to access these keys. Export ACCESS_KEY and SECRET_KEY to your environment (e.g. export ACCESS_KEY=DSJE2334JAS) to make them available to your code.
SDKs
After you set up and configure an SDK, you can follow the examples below to see how to perform common Flow Object Storage operations in JavaScript, Go, PHP, Python and Ruby.
Java Script
Go
PHP
Python 3
Ruby
Java Script
const AWS = require('aws-sdk');
const fs = require('fs'); // Needed for example below
​
const spacesEndpoint = new AWS.Endpoint('<S3-ENDPOINT>');
const s3 = new AWS.S3({
    endpoint: spacesEndpoint,
    accessKeyId: process.env.ACCESS_KEY,
    secretAccessKey: process.env.SECRET_KEY
});
Go
package main
​
import (
    "os"
    // Additional imports needed for examples below
    "fmt"
    "io"
    "strings"
    "time"
​
    "github.com/aws/aws-sdk-go/aws"
    "github.com/aws/aws-sdk-go/aws/credentials"
    "github.com/aws/aws-sdk-go/aws/session"
    "github.com/aws/aws-sdk-go/service/s3"
)
​
func main() {
    key := os.Getenv("ACCESS_KEY")
    secret := os.Getenv("SECRET_KEY")
​
    s3Config := &aws.Config{
        Credentials: credentials.NewStaticCredentials(key, secret, ""),
        Endpoint:    aws.String("https://<ENDPOINT>"),
        Region:      aws.String("us-east-1"),
    }
​
    newSession := session.New(s3Config)
    s3Client := s3.New(newSession)
​
    // ...
PHP
This SDK requires the region to be us-east-1, an AWS region name, to successfully create a new Bucket. The Flow Object Storage datacenter region is based on the 
<ENDPOINT> value.
<?php
​
// Included aws/aws-sdk-php via Composer's autoloader
require 'vendor/autoload.php';
use Aws\S3\S3Client;
​
$client = new Aws\S3\S3Client([
        'version' => 'latest',
        'region'  => 'us-east-1',
        'endpoint' => 'https://<ENDPOINT>',
        'credentials' => [
                'key'    => getenv('ACCESS_KEY'),
                'secret' => getenv('SECRET_KEY'),
            ],
]);
Python 3
import os
import boto3
​
session = boto3.session.Session()
client = session.client('s3',
                        region_name='nyc3',
                        endpoint_url='https://<ENDPOINT>',
                        aws_access_key_id=os.getenv('ACCESS_KEY'),
                        aws_secret_access_key=os.getenv('SECRET_KEY'))
Ruby
require 'aws-sdk-s3'
​
client = Aws::S3::Client.new(
  access_key_id: ENV['ACCESS_KEY'],
  secret_access_key: ENV['SECRET_KEY'],
  endpoint: 'https://<ENDPOINT>',
  region: 'us-east-1'
)
Please replace the <ENDPOINT> place holder with the correct endpoint:

Location ALP1: os.alp1.flow.swiss
Location ZRH1: os.zrh1.flow.swiss
