Uploading to google app engine bucket and marking file as a public files

Question:

Tag: ruby,google-app-engine,cdn

It seems pretty straight forward to upload files to your preexisting google storage bucket.

gsutil cp foo.txt gs://<bucket-name>

However do I make my file be publicly available?

enter image description here

So one is publicly available other is not. How do I change this programmatically, without having to do it from the web console?

And is it smart idea to use google cloud storage as a CDN for you website, hosted on google app engine too?


Answer:

gsutil acl ch -u AllUsers:R gs://<bucket-name>/foo.txt will make the object readable by anybody on the internet (gsutil is a command-line thingy, so it would typically be used via bash, cmd.exe, or some other shell language -- non-shell languages offer other APIs that are usually preferred when programming in such other languages).

As for the CDN sub-question, to quote http://cloud.google.com/storage/docs/website-configuration:

Google Cloud Storage behaves essentially like a Content Delivery Network (CDN) with no work on your part because publicly readable objects are, by default, cached in the Google Cloud Storage network.

Lastly, as the OP indicated specific interest in accessing GCS from Ruby, see http://developers.google.com/api-client-library/ruby/apis/storage/v1 for the purpose.
