Multithreaded recursive directory upload to S3 using FOG
Latest commit 4c07a72 Aug 26, 2016 @chrishein chrishein Version 0.2.3


Gem Version Build Status Coverage Status

Multithreaded recursive directory uploader to S3 using fog.

It recursively transverses all contents of the directory provided as source parameter, uploading all files to the destination bucket. A destination folder where to put the uploaded files tree inside the bucket can be specified too.

By default, it uses 5 threads to upload files in parallel, but the number can be configured as well.

Files are stored as non public if not otherwise specified.

A CLI binary is included.


Add this line to your application's Gemfile:

gem 's3_uploader'

And then execute:

$ bundle

Or install it yourself as:

$ gem install s3_uploader


	uploader ={
         :s3_key => YOUR_KEY,
         :s3_secret => YOUR_SECRET_KEY,
         :destination_dir => 'test/',
         :region => 'eu-west-1',
         :threads => 10

  uploader.upload('/tmp/test', 'mybucket')


	S3Uploader.upload('/tmp/test', 'mybucket',
		{ 	 :s3_key => YOUR_KEY,
			   :s3_secret => YOUR_SECRET_KEY,
			   :destination_dir => 'test/',
			   :region => 'eu-west-1',
			   :threads => 4,
			   :metadata => { 'Cache-Control' => 'max-age=315576000' }

Former static method upload_directory is still supported for backwards compatibility.

	S3Uploader.upload_directory('/tmp/test', 'mybucket', { :destination_dir => 'test/', :threads => 4 })

If no keys are provided, it uses S3_KEY and S3_SECRET environment variables. us-east-1 is the default region.

Metadata headers are documented here

Or as a command line binary

s3uploader -r eu-west-1 -k YOUR_KEY -s YOUR_SECRET_KEY -d test/ -t 4 /tmp/test mybucket

Again, it uses S3_KEY and S3_SECRET environment variables if non provided in parameters.

s3uploader -d test/ -t 4 /tmp/test mybucket

Compress files

If the :gzip options is used, files not already compressed are packed using GZip before upload. A GZip working directory is required in this case.

  S3Uploader.upload_directory('/tmp/test', 'mybucket',
    {    :s3_key => YOUR_KEY,
         :s3_secret => YOUR_SECRET_KEY,
         :destination_dir => 'test/',
         :region => 'eu-west-1',
         :gzip => true,
         :gzip_working_dir => '/tmp/gzip_working_dir'
