How to make multiple files in Amazon S3 public

Question

I have a folder in a bucket with multiple files. There seems to be no way to upload them and make them public straight away. So I uploaded them all, they're private, and I need to make them all public.

I've tried the aws console, it just gives an error though it works fine with works fine with folders with fewer files.

I've tried using S3 organizing in Firefox, same thing.

Is there some software or some script I can run to make all these public?

Answer 1

I had to change several hundred thousand objects. I launched an EC2 instance to run this, which makes it all go faster. You'll want to install the aws-sdk first.

require 'aws-sdk'

Aws.config.update({
  region: 'REGION_CODE_HERE',
  credentials: Aws::Credentials.new(
    'ACCESS_KEY_ID_HERE',
    'SECRET_ACCESS_KEY_HERE'
  )
})
bucket_name = 'BUCKET_NAME_HERE'

s3 = Aws::S3::Resource.new
s3.bucket(bucket_name).objects.each do |object|
  puts object.key
  object.acl.put({ acl: 'public-read' })
end
