wait_until(options = {}, &block) click to toggle source

@deprecated Use [Aws::AutoScaling::Client] wait_until instead

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

@note The waiting operation is performed on a copy. The original resource

remains unchanged.

## 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

@yieldparam [Resource] resource to be used in the waiting condition.

@raise [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.

@raise [Aws::Waiters::Errors::UnexpectedError] Raised when an error is

encountered while polling for a resource that is not expected.

@raise [NotImplementedError] Raised when the resource does not

@option options [Integer] :max_attempts (10) Maximum number of attempts @option options [Integer] :delay (10) Delay between each attempt in seconds @option options [Proc] :before_attempt (nil) Callback invoked before each attempt @option options [Proc] :before_wait (nil) Callback invoked before each wait @return [Resource] if the waiter was successful
