#detach_from_instance(options = {}) ⇒ Types::VolumeAttachment

Examples:

Options Hash (options):

  • :device (String) —

    The device name.

  • :force (Boolean) —

This option can lead to data loss or a corrupted file system. Use this option only as a last resort to detach a volume from a failed instance. The instance won't have an opportunity to flush file system caches or file system metadata. If you use this option, you must perform file system check and repair procedures.

  • :instance_id (String) —

    The ID of the instance. If you are detaching a Multi-Attach enabled volume, you must specify an instance ID.

  • :dry_run (Boolean) —

    Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

    • owner-alias - The owner alias, from an Amazon-maintained list (amazon). This is not the user-configured Amazon Web Services account alias set using the IAM console. We recommend that you use the related parameter instead of this filter.

    • owner-id - The Amazon Web Services account ID of the owner. We recommend that you use the related parameter instead of this filter.

    • progress - The progress of the snapshot, as a percentage (for example, 80%).

    • snapshot-id - The snapshot ID.

    • start-time - The time stamp when the snapshot was initiated.

    • status - The status of the snapshot (pending | completed | error).

    • storage-tier - The storage tier of the snapshot (archive | standard).

    • tag:<key> - The key/value combination of a tag assigned to the resource. Use the tag key in the filter name and the tag value as the filter value. For example, to find all resources that have a tag with the key Owner and the value TeamA, specify tag:Owner for the filter name and TeamA for the filter value.

    • tag-key - The key of a tag assigned to the resource. Use this filter to find all resources assigned a tag with a specific key, regardless of the tag value.

    • volume-id - The ID of the volume the snapshot is for.

    • volume-size - The size of the volume, in GiB.

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

Deprecated.

Use [Aws::EC2::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) —

    Raised when an error is encountered while polling for a resource that is not expected.

  • (NotImplementedError) —

    Raised when the resource does not
