Overview

Project

Represents the project that storage buckets and files belong to. All data in Google Cloud Storage belongs inside a project. A project consists of a set of users, a set of APIs, billing, authentication, and monitoring settings for those APIs.

Gcloud::Storage::Project is the main object for interacting with Google Storage. Bucket objects are created, read, updated, and deleted by Gcloud::Storage::Project.

See Gcloud#storage

Examples:

require "gcloud"

gcloud = Gcloud.new
storage = gcloud.storage

bucket = storage.bucket "my-bucket"
file = bucket.file "path/to/my-file.ext"

#bucket(bucket_name) ⇒ Gcloud::Storage::Bucket? Also known as: find_bucket

Retrieves bucket by name.

Examples:

gcloud = Gcloud.new
storage = gcloud.storage

bucket = storage.bucket "my-bucket"
puts bucket.name

Parameters:

  • bucket_name (String)

    Name of a bucket.

def bucket bucket_name
  resp = connection.get_bucket bucket_name
  if resp.success?
    Bucket.from_gapi resp.data, connection
  else
    return nil if resp.data["error"]["code"] == 404
    fail ApiError.from_response(resp)
  end
end

#buckets(prefix: nil, token: nil, max: nil) ⇒ Array<Gcloud::Storage::Bucket> Also known as: find_buckets

Retrieves a list of buckets for the given project.

Examples:

require "gcloud"

gcloud = Gcloud.new
storage = gcloud.storage

buckets = storage.buckets
buckets.each do |bucket|
  puts bucket.name
end

Retrieve all buckets with names that begin with a given prefix:

require "gcloud"

gcloud = Gcloud.new
storage = gcloud.storage

user_buckets = storage.buckets prefix: "user-"

With pagination: (See Bucket::List#token)

require "gcloud"

gcloud = Gcloud.new
storage = gcloud.storage

all_buckets = []
tmp_buckets = storage.buckets
while tmp_buckets.any? do
  tmp_buckets.each do |bucket|
    all_buckets << bucket
  end
  # break loop if no more buckets available
  break if tmp_buckets.token.nil?
  # get the next group of buckets
  tmp_buckets = storage.buckets token: tmp_buckets.token
end

Parameters:

  • prefix (String)

    Filter results to buckets whose names begin with this prefix.

  • token (String)

    A previously-returned page token representing part of the larger set of results to view.

  • max (Integer)

    Maximum number of buckets to return.

#create_bucket(bucket_name, acl: nil, default_acl: nil, cors: nil, location: nil, logging_bucket: nil, logging_prefix: nil, retries: nil, storage_class: nil, versioning: nil, website_main: nil, website_404: nil) ⇒ Gcloud::Storage::Bucket

Creates a new bucket with optional attributes. Also accepts a block for defining the CORS configuration for a static website served from the bucket. See Bucket::Cors for details.

The API call to create the bucket may be retried under certain conditions. See Backoff to control this behavior, or specify the wanted behavior in the call with the :retries: option.

You can pass website settings for the bucket, including a block that defines CORS rule. See Bucket::Cors for details.

Examples:

require "gcloud"

gcloud = Gcloud.new
storage = gcloud.storage

bucket = storage.create_bucket "my-bucket"

Specify the number of retries to attempt:

require "gcloud"

gcloud = Gcloud.new
storage = gcloud.storage

bucket = storage.create_bucket "my-bucket", retries: 5

Add CORS rules in a block:

require "gcloud"

gcloud = Gcloud.new
storage = gcloud.storage

options = {
  website_main: "index.html"
  website_404: "not_found.html"
}
bucket = storage.create_bucket "my-bucket", options do |c|
  c.add_rule ["http://example.org", "https://example.org"],
             "*",
             response_headers: ["X-My-Custom-Header"],
             max_age: 300
end

Parameters:

  • bucket_name (String)

    Name of a bucket.

  • acl (String)

    Apply a predefined set of access controls to this bucket.

    Acceptable values are:

    • auth, auth_read, authenticated, authenticated_read, authenticatedRead - Project team owners get OWNER access, and allAuthenticatedUsers get READER access.
    • private - Project team owners get OWNER access.
    • project_private, projectPrivate - Project team members get access according to their roles.
    • public, public_read, publicRead - Project team owners get OWNER access, and allUsers get READER access.
    • public_write, publicReadWrite - Project team owners get OWNER access, and allUsers get WRITER access.
  • default_acl (String)

    Apply a predefined set of default object access controls to this bucket.

    Acceptable values are:

    • auth, auth_read, authenticated, authenticated_read, authenticatedRead - File owner gets OWNER access, and allAuthenticatedUsers get READER access.
    • owner_full, bucketOwnerFullControl - File owner gets OWNER access, and project team owners get OWNER access.
    • owner_read, bucketOwnerRead - File owner gets OWNER access, and project team owners get READER access.
    • private - File owner gets OWNER access.
    • project_private, projectPrivate - File owner gets OWNER access, and project team members get access according to their roles.
    • public, public_read, publicRead - File owner gets OWNER access, and allUsers get READER access.
  • cors (String)

    The CORS rules for the bucket. Accepts an array of hashes containing the attributes specified for the resource description of cors.

  • location (String)

    The location of the bucket. Object data for objects in the bucket resides in physical storage within this region. Possible values include ASIA, EU, and US. (See the developer's guide for the authoritative list. The default value is US.

  • logging_bucket (String)

    The destination bucket for the bucket's logs. For more information, see Access Logs.

  • logging_prefix (String)

    The prefix used to create log object names for the bucket. It can be at most 900 characters and must be a valid object name . By default, the object prefix is the name of the bucket for which the logs are enabled. For more information, see Access Logs.

  • retries (Integer)

    The number of times the API call should be retried. Default is Backoff.retries.

  • storage_class (Symbol, String)

    Defines how objects in the bucket are stored and determines the SLA and the cost of storage. Values include :standard, :nearline, and :dra (Durable Reduced Availability), as well as the strings returned by Bucket#storage_class. For more information, see Storage Classes. The default value is :standard.

  • versioning (Boolean)

    Whether Object Versioning is to be enabled for the bucket. The default value is false.

  • website_main (String)

    The index page returned from a static website served from the bucket when a site visitor requests the top level directory. For more information, see How to Host a Static Website .

  • website_404 (String)

    The page returned from a static website served from the bucket when a site visitor requests a resource that does not exist. For more information, see How to Host a Static Website .

Returns:
