使用Rails从Google Cloud Storage获取共享存储桶

Question

I want to download some reports from Google Cloud Storage and I'm trying the Gcloud gem . I managed to successfully connect and now I am able to list my buckets, create one, etc.

But I can't find a way to programically get files from buckets, which are shared with me. I got and address like gs://pubsite... and I need to connect to that bucket, to download some files. How can I achieve that? Do I need to have billing enabled?

Answer 1

In order to list all the object in a bucket you can use Google Cloud Storage Object list API .

You need to provide the Bucket ID and should have the access to the bucket to read the objects. You can try the API before implementing it in your code.

I hope that helps.

Answer 2

You do not need billing enabled to download objects from a GCS bucket. Operations on GCS buckets are billed to the project that owns the bucket. You only need to enable billing in order to create a new bucket.

Downloading a single file using the Gcloud gem looks like this:

require "gcloud"

gcloud = Gcloud.new
storage = gcloud.storage
bucket = storage.bucket "pubsite"
file = bucket.file "somefile.png"
file.download "/tmp/somefile.png"

There are some examples at http://googlecloudplatform.github.io/gcloud-ruby/docs/v0.2.0/Gcloud/Storage.html
