    ({})

Options Hash (options):

  • :acl (String)

    The canned ACL to apply to the bucket.

  • :create_bucket_configuration (Types::CreateBucketConfiguration)

    The configuration information for the bucket.

  • :grant_full_control (String)

    Allows grantee the read, write, read ACP, and write ACP permissions on the bucket.

  • :grant_read (String)

    Allows grantee to list the objects in the bucket.

  • :grant_read_acp (String)

    Allows grantee to read the bucket ACL.

  • :grant_write (String)

    Allows grantee to create new objects in the bucket.

    For the bucket and object owners of existing objects, also allows deletions and overwrites of those objects.

  • :grant_write_acp (String)

    Allows grantee to write the ACL for the applicable bucket.

  • :object_lock_enabled_for_bucket (Boolean)

    Specifies whether you want S3 Object Lock to be enabled for the new bucket.

  • :object_ownership (String)

    The container element for object ownership for a bucket's ownership controls.

    BucketOwnerPreferred - Objects uploaded to the bucket change ownership to the bucket owner if the objects are uploaded with the bucket-owner-full-control canned ACL.

    ObjectWriter - The uploading account will own the object if the object is uploaded with the bucket-owner-full-control canned ACL.

    BucketOwnerEnforced - Access control lists (ACLs) are disabled and no longer affect permissions. The bucket owner automatically owns and has full control over every object in the bucket. The bucket only accepts PUT requests that don't specify an ACL or bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format.

  • :delete (required, Types::Delete)

    Container for the request.

  • :mfa (String)

    The concatenation of the authentication device's serial number, a space, and the value that is displayed on your authentication device. Required to permanently delete a versioned object if versioning is configured with MFA delete enabled.

  • :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.

  • :bypass_governance_retention (Boolean)

    Specifies whether you want to delete this object even if it has a Governance-type Object Lock in place. To use this header, you must have the s3:BypassGovernanceRetention permission.

  • :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).

  • :checksum_algorithm (String)

    Indicates the algorithm used to create the checksum for the object when using the SDK. This header will not provide any additional functionality if not using the SDK. When sending this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request. For more information, see Checking object integrity in the Amazon S3 User Guide.

    If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

    This checksum algorithm must be the same for all parts and it match the checksum value supplied in the CreateMultipartUpload request.

#multipart_uploads(options = {}) ⇒ MultipartUpload::Collection

Examples:

Request syntax with placeholder values


multipart_uploads = bucket.multipart_uploads({
  delimiter: "Delimiter",
  encoding_type: "url", # accepts url
  key_marker: "KeyMarker",
  prefix: "Prefix",
  upload_id_marker: "UploadIdMarker",
  expected_bucket_owner: "AccountId",
})

Parameters:

  • options (Hash) (defaults to: {})

    ({})

Options Hash (options):

  • :delimiter (String)

    Character you use to group keys.

    All keys that contain the same string between the prefix, if specified, and the first occurrence of the delimiter after the prefix are grouped under a single result element, CommonPrefixes. If you don't specify the prefix parameter, then the substring starts at the beginning of the key. The keys that are grouped under CommonPrefixes result element are not returned elsewhere in the response.

  • :encoding_type (String)

    Requests Amazon S3 to encode the object keys in the response and specifies the encoding method to use. 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)

    Together with upload-id-marker, this parameter specifies the multipart upload after which listing should begin.

    If upload-id-marker is not specified, only the keys lexicographically greater than the specified key-marker will be included in the list.

    If upload-id-marker is specified, any multipart uploads for a key equal to the key-marker might also be included, provided those multipart uploads have upload IDs lexicographically greater than the specified upload-id-marker.

  • :prefix (String)

    Lists in-progress uploads only for those keys that begin with the specified prefix. You can use prefixes to separate a bucket into different grouping of keys. (You can think of using prefix to make groups in the same way you'd use a folder in a file system.)

  • :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. Otherwise, any multipart uploads for a key equal to the key-marker might be included in the list only if they have an upload ID lexicographically greater than the specified upload-id-marker.

  • :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).

  version_id_marker: "VersionIdMarker",
  expected_bucket_owner: "AccountId",
})

Parameters:

  • options (Hash) (defaults to: {})

    ({})

Options Hash (options):

  • :delimiter (String)

    A delimiter is a character that you specify to group keys. All keys that contain the same string between the prefix and the first occurrence of the delimiter are grouped under a single result element in CommonPrefixes. These groups are counted as one result against the max-keys limitation. These keys are not returned elsewhere in the response.

  • :encoding_type (String)

    Requests Amazon S3 to encode the object keys in the response and specifies the encoding method to use. 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)

    Specifies the key to start with when listing objects in a bucket.

  • :prefix (String)

    Use this parameter to select only those keys that begin with the specified prefix. You can use prefixes to separate a bucket into different groupings of keys. (You can think of using prefix to make groups in the same way you'd use a folder in a file system.) You can use prefix with delimiter to roll up numerous objects into a single result under CommonPrefixes.

  • :version_id_marker (String)

    Specifies the object version you want to start listing from.

  • :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).

Parameters:

  • options (Hash) (defaults to: {})

    ({})

Options Hash (options):

  • :acl (String)

    The canned ACL to apply to the object. For more information, see Canned ACL.

    This action is not supported by Amazon S3 on Outposts.

  • :body (String, StringIO, File)

    Object data.

  • :cache_control (String)

    Can be used to specify caching behavior along the request/reply chain. For more information, see http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9.

  • :content_disposition (String)

    Specifies presentational information for the object. For more information, see https://www.rfc-editor.org/rfc/rfc6266#section-4.

  • :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. For more information, see https://www.rfc-editor.org/rfc/rfc9110.html#field.content-encoding.

  • :content_language (String)

    The language the content is in.

  • :content_length (Integer)

    Size of the body in bytes. This parameter is useful when the size of the body cannot be determined automatically. For more information, see https://www.rfc-editor.org/rfc/rfc9110.html#name-content-length.

  • :content_md5 (String)

    The base64-encoded 128-bit MD5 digest of the message (without the headers) according to RFC 1864. This header can be used as a message integrity check to verify that the data is the same data that was originally sent. Although it is optional, we recommend using the Content-MD5 mechanism as an end-to-end integrity check. For more information about REST request authentication, see REST Authentication.

  • :content_type (String)

    A standard MIME type describing the format of the contents. For more information, see https://www.rfc-editor.org/rfc/rfc9110.html#name-content-type.

  • :checksum_algorithm (String)

    Indicates the algorithm used to create the checksum for the object when using the SDK. This header will not provide any additional functionality if not using the SDK. When sending this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request. For more information, see Checking object integrity in the Amazon S3 User Guide.

    If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

  • :checksum_crc32 (String)

    This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 32-bit CRC32 checksum of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

  • :checksum_crc32c (String)

    This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 32-bit CRC32C checksum of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

  • :checksum_sha1 (String)

    This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 160-bit SHA-1 digest of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

  • :checksum_sha256 (String)

    This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 256-bit SHA-256 digest of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

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

    The date and time at which the object is no longer cacheable. For more information, see https://www.rfc-editor.org/rfc/rfc7234#section-5.3.

  • :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.

  • :key (required, String)

    Object key for which the PUT action was initiated.

  • :metadata (Hash<String,String>)

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

  • :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.

  • :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: http://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 has a valid value of aws:kms, this header specifies the ID of the Amazon Web Services Key Management Service (Amazon Web Services KMS) symmetric encryption 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. This value is stored as object metadata and automatically gets passed on to Amazon Web Services KMS for future GetObject or CopyObject operations on this object.

  • :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.

  • :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.

  • :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).

Returns:

#url(options = {}) ⇒ String

Returns a public URL for this bucket.

It will also work when provided an Access Point ARN.

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"

Examples:


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

bucket = s3.bucket(
  'arn:aws:s3:us-east-1:123456789012:accesspoint:myendpoint'
)
bucket.url
#=> "https://myendpoint-123456789012.s3-accesspoint.us-west-2.amazonaws.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.

  • :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)

    the URL for this bucket.

#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
