Defined in:

Overview

A subclass of Policy that supports access to #roles and related helpers. Attempts to call #bindings and #version= will raise a runtime error. To update the Policy version and add bindings with a newer syntax, use PolicyV3 instead by calling Bucket#policy with requested_policy_version: 3. To obtain instances of this class, call Bucket#policy without the requested_policy_version keyword argument.

Examples:

require "google/cloud/storage"

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

bucket.policy do |p|
  p.version # the value is 1
  p.remove "roles/storage.admin", "user:owner@example.com"
  p.add "roles/storage.admin", "user:newowner@example.com"
  p.roles["roles/storage.objectViewer"] = ["allUsers"]
end

storage = Google::Cloud::Storage.new

bucket = storage.bucket "my-bucket"

bucket.policy do |p|
  p.add "roles/storage.admin", "user:newowner@example.com"
end

Parameters:
