Step 5: Add AWS SDK code - AWS Cloud9

Step 5: Add AWS SDK code

(Previous step: Step 4: Install and configure the AWS SDK for Ruby)

In this step, you provide code to interact with Amazon S3. This code creates a bucket, lists your available buckets, and then deletes the bucket that was created. (You will run this code in the next step.)

In the AWS Cloud9 IDE, create a file with the following code and save the file with the name s3.rb.

require 'aws-sdk' if ARGV.length < 2 puts "Usage: ruby s3.rb <the bucket name> <the AWS Region to use>\n" + "Example: ruby s3.rb my-test-bucket us-east-2" end bucket_name = ARGV[0] region = ARGV[1] s3 = Aws::S3::Client.new(region: region) # Lists all of your available buckets in this AWS Region. def list_my_buckets(s3) resp = s3.list_buckets() puts "My buckets now are:\n\n" resp.buckets.each do |bucket| puts bucket.name end end list_my_buckets(s3) # Create a new bucket. begin puts "\nCreating a new bucket named '#{bucket_name}'...\n\n" s3.create_bucket({ bucket: bucket_name, create_bucket_configuration: { location_constraint: region } }) s3.wait_until(:bucket_exists, {bucket: bucket_name,}) rescue Aws::S3::Errors::BucketAlreadyExists puts "Cannot create the bucket. " + "A bucket with the name '#{bucket_name}' already exists. Exiting." exit(false) end list_my_buckets(s3) # Delete the bucket you just created. puts "\nDeleting the bucket named '#{bucket_name}'...\n\n" s3.delete_bucket(bucket: bucket_name) s3.wait_until(:bucket_not_exists, {bucket: bucket_name,}) list_my_buckets(s3)
