Writing files via PowerShell to AWS S3 buckets

readme.md

PowerShell

This works for PowerShell >= 5.1

You need to install the AWS tools beforehand with

Install-Module -Name AWS.Tools.Installer
Install-AWSToolsModule S3

List all commands of that module and syntax of a specific function/cmdlet

Get-command -module aws.tools.s3
get-command -Name  Write-S3Object -Syntax
get-help Write-S3Object -full
Get-help Write-S3Object -parameter *

Then create a profile for the credentials

Set-AWSCredential -AccessKey "abc" -SecretKey "def" -StoreAs "s3test"

Now you can create a regular script to upload files

Write-S3Object -BucketName "apteco-cloud-customer" -File .\test.txt -ProfileName s3test

To see the list of files you have created, just use this command

# List all files/objects in bucket
Get-S3Object -ProfileName s3test -BucketName "apteco-cloud-customer"

Without a profile you could use this

$credentials = [Amazon.Runtime.BasicAWSCredentials]::new($accessKey, $secretKey)
$region = "eu-central-1"
Get-S3Object -BucketName "your-bucket-name" -Credential $credentials -Region $region

Python

This needs some packages to be installed, e.g. with pip from PowerShell or Bash

pip install boto3

Then you can directly jump into your code. This example directly enters the credentials. To see more secure possibilites, please have a look at https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html

import boto3
boto3.client('s3',aws_access_key_id='abc',aws_secret_access_key='def')
s3_client.upload_file(Filename='./hw.txt',Bucket='apteco-cloud-client',Key='hw.txt')

To see all uploaded files, simply output this dict

s3_client.list_objects(Bucket='apteco-cloud-srk')['Contents']
