end

#copy_to(target, options = {}) ⇒ Object

Note:

If you need to copy to a bucket in a different region, use #copy_from.

Copies this object to another object. Use multipart_copy: true for large objects. This is required for objects that exceed 5GB.

Examples:

Basic object copy


bucket = Aws::S3::Bucket.new('source-bucket')
object = bucket.object('source-key')

# target as String
object.copy_to('target-bucket/target-key')

# target as Hash
object.copy_to(bucket: 'target-bucket', key: 'target-key')

# target as Aws::S3::Object
object.copy_to(bucket.object('target-key'))

Managed copy of large objects


# uses multipart upload APIs to copy object
object.copy_to('src-bucket/src-key', multipart_copy: true)

Parameters:

  • target (S3::Object, String, Hash)

    Where to copy the object data to. target must be one of the following:

    • Aws::S3::Object
    • Hash - with :bucket and :key
    • String - formatted like "target-bucket-name/target-key"

#presigned_url(http_method, params = {}) ⇒ String

Generates a pre-signed URL for this object.

Examples:

Pre-signed GET URL, valid for one hour


obj.presigned_url(:get, expires_in: 3600)
#=> "https://bucket-name.s3.amazonaws.com/object-key?..."

Pre-signed PUT with a canned ACL


# the object uploaded using this URL will be publicly accessible
obj.presigned_url(:put, acl: 'public-read')
#=> "https://bucket-name.s3.amazonaws.com/object-key?..."

Parameters:

  • http_method (Symbol)

    The HTTP method to generate a presigned URL for. Valid values are :get, :put, :head, and :delete.

  • params (Hash) (defaults to: {})

    Additional request parameters to use when generating the pre-signed URL. See the related documentation in Client for accepted params.

    HTTP Method Client Method
    :get Client#get_object
    :put Client#put_object
    :head Client#head_object
    :delete Client#delete_object

Options Hash (params):

  • :virtual_host (Boolean) — default: false

    When true the presigned URL will use the bucket name as a virtual host.

    bucket = Aws::S3::Bucket.new('my.bucket.com') bucket.object('key').presigned_url(virtual_host: true) #=> "http://my.bucket.com/key?..."

  • :expires_in (Integer) — default: 900

    Number of seconds before the pre-signed URL expires. This may not exceed one week (604800 seconds). Note that the pre-signed URL is also only valid as long as credentials used to sign it are. For example, when using IAM roles, temporary tokens generated for signing also have a default expiration which will affect the effective expiration of the pre-signed URL.

Returns:

  • (String)

Raises:

  • (ArgumentError)

    Raised if :expires_in exceeds one week (604800 seconds).

#upload_file(source, options = {}) ⇒ Boolean

Uploads a file from disk to the current object in S3.

# large files are automatically split into parts
# and the parts are uploaded in parallel
obj.upload_file('/path/to/very_large_file')

Parameters:

  • source (String, Pathname, File, Tempfile)

    A file or path to a file on the local file system that should be uploaded to this object. If you pass an open file object, then it is your responsibility to close the file object once the upload completes.

    a customizable set of options

Options Hash (options):

  • :multipart_threshold (Integer) — default: 15728640

    Files larger than :multipart_threshold are uploaded using the S3 multipart APIs. Default threshold is 15MB.

Returns:

  • (Boolean)

    Returns true when the object is uploaded without any errors.

Raises:

  • (MultipartUploadError)

#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

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
