How to copy all files in a folder on s3 using Fog in Ruby

How do I copy all the files present in an s3 directory(same prefix) to another directory in the same bucket using fog?

For eg: Copy all files with prefix <bucket>/foo/ to <bucket>/bar/

Solution

  • I don't think there is a direct way to do that per se, and that instead you would need to iterate over the appropriate files to do the move. I think it would look something like this:

    require 'rubygems'
require 'fog'

# create a connection
connection = Fog::Storage.new({
  provider:             'AWS',
  aws_access_key_id:     YOUR_AWS_ACCESS_KEY_ID,
  aws_secret_access_key: YOUR_AWS_SECRET_ACCESS_KEY
})

directory = connection.directories.get(BUCKET, prefix: '/foo/')

directory.files.each do |file|
  file.copy(BUCKET, "/bar/#{file.key.split('/').last}")
end
