Golang and AWS

Using Golang to interact with AWS services.

Prerequisites

AWS account

You need to create an AWS account.

Set the configuration

You can either set the configuration with Environment variables or Shared Credentials, here we'll be using shared credentials files. To do so, you need to add a file named credentials in your home directory.
Example for Windows, create the file C:\Users\xxxxx\.aws\credentials with :

[default]
aws_access_key_id = YOUR_KEY
aws_secret_access_key = YOUR_SECRET
region=your-region

Permissions

Here are the permissions needed for this tutorial :

To successfully complete the PutObject request, you must have the s3:PutObject in your IAM permissions.
To successfully change the objects acl of your PutObject request, you must have the s3:PutObjectAcl in your IAM permissions.

Example 1 : Play with databases (DynamoDB)

In this example we will use DynamoDB databases.

To list tables : go run main.go example1 list
To put stuff into table : go run main.go example1 put -t yourTableName

Example 2 : Play with buckets (S3)

In this example we will use S3 buckets.

To list buckets : go run main.go example2 list
To put stuff into bucket : go run main.go example2 put -t yourBucketName
