Overview

Bindings

Enumerable object for managing Cloud IAM bindings associated with a bucket.

Examples:

Updating a Policy from version 1 to version 3:

require "google/cloud/storage"

storage = Google::Cloud::Storage.new
bucket = storage.bucket "my-bucket"

bucket.uniform_bucket_level_access = true

bucket.policy requested_policy_version: 3 do |p|
  p.version # the value is 1
  p.version = 3 # Must be explicitly set to opt-in to support for conditions.

  expr = "resource.name.startsWith(\"projects/_/buckets/bucket-name/objects/prefix-a-\")"
  p.bindings.insert({
                      role: "roles/storage.admin",
                      members: ["user:[email protected]"],
                      condition: {
                        title: "my-condition",
                        description: "description of condition",
                        expression: expr
                      }
                    })
end

Instance Method Details

#each {|binding| ... } ⇒ Enumerator

Calls the block once for each binding in the collection, passing a Google::Cloud::Storage::Policy::Binding object as parameter. A Google::Cloud::Storage::Policy::Binding object is passed even when the arguments to #insert were hash objects.

If no block is given, an enumerator is returned instead.

Examples:

require "google/cloud/storage"

storage = Google::Cloud::Storage.new
bucket = storage.bucket "my-bucket"

policy = bucket.policy requested_policy_version: 3
policy.bindings.each do |binding|
  puts binding.role
end

Yields:

  • (binding) —

    A binding in this bindings collection.

Yield Parameters:

Returns:

  • (Enumerator)

  @bindings.each { |binding| yield binding }
end

#insert(*bindings) ⇒ Bindings

Adds a binding or bindings to the collection. The arguments may be Google::Cloud::Storage::Policy::Binding objects or equivalent hash objects that will be implicitly coerced to binding objects.

Examples:

Updating a Policy from version 1 to version 3:

require "google/cloud/storage"

storage = Google::Cloud::Storage.new
bucket = storage.bucket "my-bucket"

bucket.uniform_bucket_level_access = true

bucket.policy requested_policy_version: 3 do |p|
  p.version # the value is 1
  p.version = 3 # Must be explicitly set to opt-in to support for conditions.

  expr = "resource.name.startsWith(\"projects/_/buckets/bucket-name/objects/prefix-a-\")"
  p.bindings.insert({
                      role: "roles/storage.admin",
                      members: ["user:[email protected]"],
                      condition: {
                        title: "my-condition",
                        description: "description of condition",
                        expression: expr
                      }
                    })

def insert *bindings
  bindings = coerce_bindings(*bindings)
  @bindings += bindings
  self
end

#remove(*bindings) ⇒ Bindings

Deletes the binding or bindings from the collection that are equal to the arguments. The specification arguments may be Google::Cloud::Storage::Policy::Binding objects or equivalent hash objects that will be implicitly coerced to binding objects.

Examples:

require "google/cloud/storage"

storage = Google::Cloud::Storage.new
bucket = storage.bucket "my-bucket"

bucket.policy requested_policy_version: 3 do |p|
  expr = "resource.name.startsWith(\"projects/_/buckets/bucket-name/objects/prefix-a-\")"
  p.bindings.remove({
                      role: "roles/storage.admin",
                      members: ["user:[email protected]"],
                      condition: {
                        title: "my-condition",
                        description: "description of condition",
                        expression: expr
                      }
