Parameters:

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

    ({})

Options Hash (options):

  • :acl (String) —

    The canned ACL to apply to the object.

    This action is not supported by Amazon S3 on Outposts.

  • :cache_control (String) —

    Specifies caching behavior along the request/reply chain.

  • :checksum_algorithm (String) —

    Indicates the algorithm you want Amazon S3 to use to create the checksum for the object. For more information, see [Checking object integrity] in the *Amazon S3 User Guide*.

    [1]: docs.aws.amazon.com/AmazonS3/latest/userguide/checking-object-integrity.html

  • :content_disposition (String) —

    Specifies presentational information for the object.

  • :content_encoding (String) —

    Specifies what content encodings have been applied to the object and thus what decoding mechanisms must be applied to obtain the media-type referenced by the Content-Type header field.

  • :content_language (String) —

    The language the content is in.

  • :content_type (String) —

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

  • :copy_source (required, String) —

    Specifies the source object for the copy operation. You specify the value in one of two formats, depending on whether you want to access the source object through an [access point]:

    • For objects not accessed through an access point, specify the name of the source bucket and the key of the source object, separated by a slash (/). For example, to copy the object ‘reports/january.pdf` from the bucket `awsexamplebucket`, use `awsexamplebucket/reports/january.pdf`. The value must be URL-encoded.

    • For objects accessed through access points, specify the Amazon Resource Name (ARN) of the object as accessed through the access point, in the format ‘arn:aws:s3:<Region>:<account-id>:accesspoint/<access-point-name>/object/<key>`. For example, to copy the object `reports/january.pdf` through access point `my-access-point` owned by account `123456789012` in Region `us-west-2`, use the URL encoding of `arn:aws:s3:us-west-2:123456789012:accesspoint/my-access-point/object/reports/january.pdf`. The value must be URL encoded.

      <note markdown=“1”> Amazon S3 supports copy operations using access points only when the source and destination buckets are in the same Amazon Web Services Region.

      </note>

      Alternatively, for objects accessed through Amazon S3 on Outposts, specify the ARN of the object as accessed in the format ‘arn:aws:s3-outposts:<Region>:<account-id>:outpost/<outpost-id>/object/<key>`. For example, to copy the object `reports/january.pdf` through outpost `my-outpost` owned by account `123456789012` in Region `us-west-2`, use the URL encoding of `arn:aws:s3-outposts:us-west-2:123456789012:outpost/my-outpost/object/reports/january.pdf`. The value must be URL-encoded.

    To copy a specific version of an object, append ‘?versionId=<version-id>` to the value (for example, `awsexamplebucket/reports/january.pdf?versionId=QUpfdndhfd8438MNFDN93jdnJFkdmqnh893`). If you don’t specify a version ID, Amazon S3 copies the latest version of the source object.

    [1]: docs.aws.amazon.com/AmazonS3/latest/userguide/access-points.html

  • :copy_source_if_match (String) —

    Copies the object if its entity tag (ETag) matches the specified tag.

  • :copy_source_if_none_match (String) —

    Copies the object if its entity tag (ETag) is different than the specified ETag.

  • :copy_source_if_unmodified_since (Time, DateTime, Date, Integer, String) —

    Copies the object if it hasn’t been modified since the specified time.

  • :expires (Time, DateTime, Date, Integer, String) —

    The date and time at which the object is no longer cacheable.

  • :grant_full_control (String) —

    Gives the grantee READ, READ_ACP, and WRITE_ACP permissions on the object.

    This action is not supported by Amazon S3 on Outposts.

  • :grant_read (String) —

    Allows grantee to read the object data and its metadata.

    This action is not supported by Amazon S3 on Outposts.

  • :grant_read_acp (String) —

    Allows grantee to read the object ACL.

    This action is not supported by Amazon S3 on Outposts.

  • :grant_write_acp (String) —

    Allows grantee to write the ACL for the applicable object.

    This action is not supported by Amazon S3 on Outposts.

  • :metadata (Hash<String,String>) —

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

  • :metadata_directive (String) —

    Specifies whether the metadata is copied from the source object or replaced with metadata provided in the request.

  • :tagging_directive (String) —

    Specifies whether the object tag-set are copied from the source object or replaced with tag-set provided in the request.

  • :server_side_encryption (String) —

    The server-side encryption algorithm used when storing this object in Amazon S3 (for example, AES256, aws:kms).

  • :storage_class (String) —

    By default, Amazon S3 uses the STANDARD Storage Class to store newly created objects. The STANDARD storage class provides high durability and high availability. Depending on performance needs, you can specify a different Storage Class. Amazon S3 on Outposts only uses the OUTPOSTS Storage Class. For more information, see [Storage Classes] in the *Amazon S3 User Guide*.

    [1]: docs.aws.amazon.com/AmazonS3/latest/dev/storage-class-intro.html

  • :website_redirect_location (String) —

    If the bucket is configured as a website, redirects requests for this object to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata.

  • :sse_customer_algorithm (String) —

    Specifies the algorithm to use to when encrypting the object (for example, AES256).

  • :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 S3 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) —

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

  • :ssekms_key_id (String) —

    Specifies the Amazon Web Services KMS key ID to use for object encryption. All GET and PUT requests for an object protected by Amazon Web Services KMS will fail if not made via SSL or using SigV4. For information about configuring using any of the officially supported Amazon Web Services SDKs and Amazon Web Services CLI, see [Specifying the Signature Version in Request Authentication] in the *Amazon S3 User Guide*.

    [1]: docs.aws.amazon.com/AmazonS3/latest/dev/UsingAWSSDK.html#specify-signature-version

  • :ssekms_encryption_context (String) —

    Specifies the Amazon Web Services KMS Encryption Context to use for object encryption. The value of this header is a base64-encoded UTF-8 string holding JSON with the encryption context key-value pairs.

  • :bucket_key_enabled (Boolean) —

    Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using AWS KMS (SSE-KMS). Setting this header to ‘true` causes Amazon S3 to use an S3 Bucket Key for object encryption with SSE-KMS.

    Specifying this header with a COPY action doesn’t affect bucket-level settings for S3 Bucket Key.

  • :copy_source_sse_customer_algorithm (String) —

    Specifies the algorithm to use when decrypting the source object (for example, AES256).

  • :copy_source_sse_customer_key (String) —

    Specifies the customer-provided encryption key for Amazon S3 to use to decrypt the source object. The encryption key provided in this header must be one that was used when the source object was created.

  • :copy_source_sse_customer_key_md5 (String) —

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

  • :request_payer (String) —

    Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see [Downloading Objects in Requester Pays Buckets] in the *Amazon S3 User Guide*.

    [1]: docs.aws.amazon.com/AmazonS3/latest/dev/ObjectsinRequesterPaysBuckets.html

  • :tagging (String) —

    The tag-set for the object destination object this value must be used in conjunction with the ‘TaggingDirective`. The tag-set must be encoded as URL Query parameters.

#presigned_request(method, params = {}) ⇒ String, Hash

Allows you to create presigned URL requests for S3 operations. This method returns a tuple containing the URL and the signed X-amz-* headers to be used with the presigned url.

Examples:

Pre-signed GET URL, valid for one hour


obj.presigned_request(: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_request(:put, acl: 'public-read')
#=> ["https://bucket-name.s3.amazonaws.com/object-key?...",
 {"x-amz-acl"=>"public-read"}]

Parameters:

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_request(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, Hash) —

    A tuple with a presigned URL and headers that should be included with the request.

Raises:

  • (ArgumentError) —

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

#presigned_url(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?..."

Pre-signed UploadPart PUT


# the object uploaded using this URL will be publicly accessible
obj.presigned_url(:upload_part, part_number: 1, upload_id: 'uploadIdToken')
#=> "https://bucket-name.s3.amazonaws.com/object-key?..."

Parameters:

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).

Returns the public (un-signed) URL for this object.

s3.bucket('bucket-name').object('obj-key').public_url
#=> "https://bucket-name.s3.amazonaws.com/obj-key"

To use virtual hosted bucket url. Uses https unless secure: false is set. If the bucket name contains dots (.) then you will need to set secure: false.

s3.bucket('my-bucket.com').object('key')
  .public_url(virtual_host: true)
#=> "https://my-bucket.com/key"

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 the bucket.

  • :secure (Boolean) — default: true —

    When ‘false`, http will be used with virtual_host. This is required when the bucket name has a dot (.) in it.

Returns:

  • (String)

  • :server_side_encryption (String) —

    The server-side encryption algorithm used when storing this object in Amazon S3 (for example, AES256, aws:kms).

  • :storage_class (String) —

    By default, Amazon S3 uses the STANDARD Storage Class to store newly created objects. The STANDARD storage class provides high durability and high availability. Depending on performance needs, you can specify a different Storage Class. Amazon S3 on Outposts only uses the OUTPOSTS Storage Class. For more information, see [Storage Classes] in the *Amazon S3 User Guide*.

    [1]: docs.aws.amazon.com/AmazonS3/latest/dev/storage-class-intro.html

  • :website_redirect_location (String) —

    If the bucket is configured as a website, redirects requests for this object to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata. For information about object metadata, see [Object Key and Metadata].

    In the following example, the request header sets the redirect to an object (anotherPage.html) in the same bucket:

    ‘x-amz-website-redirect-location: /anotherPage.html`

    In the following example, the request header sets the object redirect to another website:

    ‘x-amz-website-redirect-location: www.example.com/`

    For more information about website hosting in Amazon S3, see [Hosting Websites on Amazon S3] and [How to Configure Website Page Redirects].

  • :sse_customer_algorithm (String) —

    Specifies the algorithm to use to when encrypting the object (for example, AES256).

  • :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 S3 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) —

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

  • :ssekms_key_id (String) —

    If ‘x-amz-server-side-encryption` is present and has the value of `aws:kms`, this header specifies the ID of the Amazon Web Services Key Management Service (Amazon Web Services KMS) symmetrical customer managed key that was used for the object. If you specify `x-amz-server-side-encryption:aws:kms`, but do not provide` x-amz-server-side-encryption-aws-kms-key-id`, Amazon S3 uses the Amazon Web Services managed key to protect the data. If the KMS key does not exist in the same account issuing the command, you must use the full ARN and not just the ID.

  • :ssekms_encryption_context (String) —

    Specifies the Amazon Web Services KMS Encryption Context to use for object encryption. The value of this header is a base64-encoded UTF-8 string holding JSON with the encryption context key-value pairs.

  • :bucket_key_enabled (Boolean) —

    Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using AWS KMS (SSE-KMS). Setting this header to ‘true` causes Amazon S3 to use an S3 Bucket Key for object encryption with SSE-KMS.

    Specifying this header with a PUT action doesn’t affect bucket-level settings for S3 Bucket Key.

  • :request_payer (String) —

    Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see [Downloading Objects in Requester Pays Buckets] in the *Amazon S3 User Guide*.

    [1]: docs.aws.amazon.com/AmazonS3/latest/dev/ObjectsinRequesterPaysBuckets.html

  • :tagging (String) —

    The tag-set for the object. The tag-set must be encoded as URL Query parameters. (For example, “Key1=Value1”)

  • :object_lock_mode (String) —

    The Object Lock mode that you want to apply to this object.

  • :object_lock_retain_until_date (Time, DateTime, Date, Integer, String) —

    The date and time when you want this object’s Object Lock to expire. Must be formatted as a timestamp parameter.

  • :object_lock_legal_hold_status (String) —

    Specifies whether a legal hold will be applied to this object. For more information about S3 Object Lock, see [Object Lock].

    [1]: docs.aws.amazon.com/AmazonS3/latest/dev/object-lock.html

  • :expected_bucket_owner (String) —

    The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code ‘403 Forbidden` (access denied).

#replication_status ⇒ String

Amazon S3 can return this header if your request involves a bucket that is either a source or a destination in a replication rule.

In replication, you have a source bucket on which you configure replication and destination bucket or buckets where Amazon S3 stores object replicas. When you request an object (‘GetObject`) or object metadata (`HeadObject`) from these buckets, Amazon S3 will return the `x-amz-replication-status` header in the response as follows:

  • **If requesting an object from the source bucket**, Amazon S3 will return the ‘x-amz-replication-status` header if the object in your request is eligible for replication.

    For example, suppose that in your replication configuration, you specify object prefix ‘TaxDocs` requesting Amazon S3 to replicate objects with key prefix `TaxDocs`. Any objects you upload with this key name prefix, for example `TaxDocs/document1.pdf`, are eligible for replication. For any object request with this key name prefix, Amazon S3 will return the `x-amz-replication-status` header with value PENDING, COMPLETED or FAILED indicating object replication status.

  • **If requesting an object from a destination bucket**, Amazon S3 will return the ‘x-amz-replication-status` header with value REPLICA if the object in your request is a replica that Amazon S3 created and there is no replica modification replication in progress.

  • **When replicating objects to multiple destination buckets**, the ‘x-amz-replication-status` header acts differently. The header of the source object will only return a value of COMPLETED when replication is successful to all destinations. The header will remain at value PENDING until replication has completed for all destinations. If one or more destinations fails replication the header will return FAILED.

For more information, see [Replication].

#restore ⇒ String

If the object is an archived object (an object whose storage class is GLACIER), the response includes this header if either the archive restoration is in progress (see [RestoreObject] or an archive copy is already restored.

If an archive copy is already restored, the header value indicates when Amazon S3 is scheduled to delete the object copy. For example:

‘x-amz-restore: ongoing-request=“false”, expiry-date=“Fri, 21 Dec 2012 00:00:00 GMT”`

If the object restoration is in progress, the header returns the value ‘ongoing-request=“true”`.

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

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

# small files are uploaded in a single API call
obj.upload_file('/path/to/file')

Files larger than or equal to ‘:multipart_threshold` are uploaded using the Amazon S3 multipart upload APIs.

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

The response of the S3 upload API is yielded if a block given.

# API response will have etag value of the file
obj.upload_file('/path/to/file') do |response|
  etag = response.etag
end

You can provide a callback to monitor progress of the upload:

# bytes and totals are each an array with 1 entry per part
progress = Proc.new do |bytes, totals|
  puts bytes.map.with_index { |b, i| "Part #{i+1}: #{b} / #{totals[i]}"}.join(' ') + "Total: #{100.0 * bytes.sum / totals.sum }%" }
end
obj.upload_file('/path/to/file', progress_callback: progress)

Parameters:

  • source (String, Pathname, File, Tempfile) —

    A file on the local file system that will be uploaded as this object. This can either be a String or Pathname to the file, an open File object, or an open Tempfile object. If you pass an open File or Tempfile object, then you are responsible for closing it after the upload completes. When using an open Tempfile, rewind it before uploading or else the object will be empty.

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

    a customizable set of options

Options Hash (options):

  • :multipart_threshold (Integer) — default: 104857600 —

    Files larger than or equal to ‘:multipart_threshold` are uploaded using the S3 multipart APIs. Default threshold is 100MB.

  • :thread_count (Integer) — default: 10 —

    The number of parallel multipart uploads. This option is not used if the file is smaller than ‘:multipart_threshold`.

  • :progress_callback (Proc) —

    A Proc that will be called when each chunk of the upload is sent. It will be invoked with [bytes_read], [total_sizes]

Yields:

  • (response)

Returns:

  • (Boolean) —

    Returns ‘true` when the object is uploaded without any errors.

Raises:

  • (MultipartUploadError) —

    If an object is being uploaded in parts, and the upload can not be completed, then the upload is aborted and this error is raised. The raised error has a ‘#errors` method that returns the failures that caused the upload to be aborted.

  true
end

#upload_stream(options = {}, &block) ⇒ Boolean

Uploads a stream in a streaming fashion to the current object in S3.

Passed chunks automatically split into multipart upload parts and the parts are uploaded in parallel. This allows for streaming uploads that never touch the disk.

Note that this is known to have issues in JRuby until jruby-9.1.15.0, so avoid using this with older versions of JRuby.

Examples:

Streaming chunks of data

obj.upload_stream do |write_stream|
  10.times { write_stream << 'foo' }
end

Streaming chunks of data

obj.upload_stream do |write_stream|
  IO.copy_stream(IO.popen('ls'), write_stream)
end

Streaming chunks of data

obj.upload_stream do |write_stream|
  IO.copy_stream(STDIN, write_stream)
end

Parameters:

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

    a customizable set of options

Options Hash (options):

  • :thread_count (Integer) — default: 10 —

    The number of parallel multipart uploads

  • :tempfile (Boolean) — default: false —

    Normally read data is stored in memory when building the parts in order to complete the underlying multipart upload. By passing ‘:tempfile => true` data read will be temporarily stored on disk reducing the memory footprint vastly.

  • :part_size (Integer) — default: 5242880 —

    Define how big each part size but the last should be. Default ‘:part_size` is `5 * 1024 * 1024`.

Returns:

  • (Boolean) —

    Returns ‘true` when the object is uploaded without any errors.

Raises:

  • (MultipartUploadError) —

    If an object is being uploaded in parts, and the upload can not be completed, then the upload is aborted and this error is raised. The raised error has a ‘#errors` method that returns the failures that caused the upload to be aborted.

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