Using the ruby aws-sdk gem, presigned post uploads work correctly with AWS S3 proper and fail when attempting on Spaces. So there is some kind of non-interoperability going on.
I setup everything following this guide, https://devcenter.heroku.com/articles/direct-to-s3-image-uploads-in-rails
It’s failing with this error:
<Error>
<Code>InvalidArgument</Code>
<Message>Missing access key</Message>
<BucketName>bucket</BucketName>
<RequestId>tx0000000000000000...</RequestId>
<HostId>1d183-nyc3a-nyc</HostId>
</Error>
Again, the code works with S3, fails with Spaces. Has anyone got this to work?

Here is a working example using the aws-sdk-v1 gem, which is required until Spaces supports v4 signatures.
class FoobarController < ApplicationController
layout false
def index
AWS.config(
access_key_id: 'ACCESS_KEY_ID',
secret_access_key: 'SECRET_ACCESS_KEY',
s3_endpoint: 'nyc3.digitaloceanspaces.com',
region: 'ny3'
)
bucket = AWS::S3.new.buckets['BUCKET-NAME']
@s3_direct_post = bucket.presigned_post(
key: "uploads/#{SecureRandom.uuid}/${filename}",
success_action_status: '201',
acl: 'public-read',
content_type: ''
)
end
end
<%= form_tag(@s3_direct_post.url.to_s, enctype: 'multipart/form-data', authenticity_token: false, enforce_utf8: false) do %>
<% @s3_direct_post.fields.each do |field, value| %>
<%= hidden_field_tag field, value %>
<% end %>
<%= file_field_tag :file %>
<%= submit_tag 'Upload' %>
<% end %>
Please let me know if DigitalOcean supports the “Policy” and “X-Amz-Signature” headers? (AWS V4) TIA.

@PDGBen we now have v4 support in NYC3, and soon will have the same in AMS3. HTH
