#create_version(options = {}) ⇒ PolicyVersion

Examples:

Parameters:

  • options (Hash) (defaults to: {}) —

    ({})

Options Hash (options):

  • :policy_document (required, String) —

    The JSON policy document that you want to use as the content for this new version of the policy.

    You must provide policies in JSON format in IAM. However, for AWS CloudFormation templates formatted in YAML, you can provide the policy in JSON or YAML format. AWS CloudFormation always converts a YAML policy to JSON format before submitting it to IAM.

    The regex pattern used to validate this parameter is a string of characters consisting of the following:

    • Any printable ASCII character ranging from the space character (\u0020) through the end of the ASCII character range

    • The printable characters in the Basic Latin and Latin-1 Supplement character set (through \u00FF)

    • The special characters tab (\u0009), line feed (\u000A), and carriage return (\u000D)

  • :set_as_default (Boolean) —

    Specifies whether to set this version as the policy's default version.

    When this parameter is true, the new policy version becomes the operative version. That is, it becomes the version that is in effect for the IAM users, groups, and roles that the policy is attached to.

#wait_until(options = {}) {|resource| ... } ⇒ Resource

Deprecated.

Use [Aws::IAM::Client] #wait_until instead

Note:

The waiting operation is performed on a copy. The original resource remains unchanged.

Waiter polls an API operation until a resource enters a desired state.

Basic Usage

Waiter will polls until it is successful, it fails by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop until condition is true
resource.wait_until(options) {|resource| condition}

Example

instance.wait_until(max_attempts:10, delay:5) do |instance|
  instance.state.name == 'running'
end

Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. The waiting condition is set by passing a block to #wait_until:

# poll for ~25 seconds
resource.wait_until(max_attempts:5,delay:5) {|resource|...}

Callbacks

You can be notified before each polling attempt and before each delay. If you throw :success or :failure from these callbacks, it will terminate the waiter.

started_at = Time.now
# poll for 1 hour, instead of a number of attempts
proc = Proc.new do |attempts, response|
  throw :failure if Time.now - started_at > 3600
end

  # disable max attempts
instance.wait_until(before_wait:proc, max_attempts:nil) {...}

Handling Errors

When a waiter is successful, it returns the Resource. When a waiter fails, it raises an error.

begin
  resource.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

attempts attempt in seconds invoked before each attempt invoked before each wait

Parameters:

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :max_attempts (Integer) — default: 10 —

    Maximum number of

  • :delay (Integer) — default: 10 —

    Delay between each

  • :before_attempt (Proc) — default: nil —

    Callback

  • :before_wait (Proc) — default: nil —

    Callback

Yield Parameters:

  • resource (Resource) —

    to be used in the waiting condition.

Returns:

  • (Resource) —

    if the waiter was successful

Raises:

  • (Aws::Waiters::Errors::FailureStateError) —

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

    yet successful.

  • (Aws::Waiters::Errors::UnexpectedError) —
