Options Hash (options):

  • :delimiter (String) —

    Character you use to group keys.

An object key may contain any Unicode character; however, XML 1.0 parser cannot parse some characters, such as characters with an ASCII value from 0 to 10. For characters that are not supported in XML 1.0, you can add this parameter to request that Amazon S3 encode the keys in the response.

  • :key_marker (String) —

  • :prefix (String) —

    Lists in-progress uploads only for those keys that begin with the specified prefix.

  • :upload_id_marker (String) —

    Together with key-marker, specifies the multipart upload after which listing should begin. If key-marker is not specified, the upload-id-marker parameter is ignored.

    Size of the body in bytes. This parameter is useful when the size of the body cannot be determined automatically.

  • :content_type (String) —

    A standard MIME type describing the format of the object data.

  • :metadata (Hash<String,String>) —

    A map of metadata to store with the object in S3.

  • :sse_customer_key (String) —

    Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side​-encryption​-customer-algorithm header.

  • :sse_customer_key_md5 (String) —

#url(options = {}) ⇒ String

Returns a public URL for this bucket.

bucket = s3.bucket('bucket-name')
bucket.url
#=> "https://bucket-name.s3.amazonaws.com"

You can pass ‘virtual_host: true` to use the bucket name as the host name.

bucket = s3.bucket('my.bucket.com')
bucket.url(virtual_host: true)
#=> "http://my.bucket.com"

Parameters:

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

    a customizable set of options

Options Hash (options):

  • :virtual_host (Boolean) — default: false —

    When ‘true`, the bucket name will be used as the host name. This is useful when you have a CNAME configured for this bucket.

Returns:

  • (String) —

    the URL for this bucket.

#wait_until(options = {}, &block) ⇒ Resource

Deprecated.

Use [Aws::S3::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) {|instance| instance.state.name == 'running' }

## 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

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
