Create Container Comparison

Creating a Container with OpenStack

Creating a container requires at least two, and at most three, things:

• URL (I list this here because it secretly implies a region to create the bucket in)
• Account ID (query parameter; apparently a tenant ID? OpenStack docs are ambiguous here)
• Container name (query parameter)
• Metadata (optional, encoded in headers)

Note that ACL or permissions-related data cannot be provided through this call.

Returns 201 if successful.

Creating a Container with S3

• Bucket name (must be DNS compatible; passed as a header)
• Authorization token (header)
• Bucket Region (passed inside an XML element; constrains where the bucket is created)
• Access privileges (header; optional)

Note that the bucket region in S3 has no corresponding counterpart in OpenStack's request; this is because the URL you hit in OpenStack to create the container is already tied to a specific region.

Returns 200 if successful, along with some metadata on the bucket created.

Windows Azure

See http://www.windowsazure.com/en-us/develop/net/how-to-guides/blob-storage/#create-container for an interesting work-flow. You need to get a "reference" to a container, even if it doesn't exist. Then, you create it if it doesn't exist with another call. This document doesn't illustrate wire-level transactions, though, so this might be a client-side abstraction. I'm still researching.
