})

Parameters:

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

    ({})

Options Hash (options):

  • :acl (String) —

    The canned ACL to apply to the bucket.

    This functionality is not supported for directory buckets.

  • :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.

    This functionality is not supported for directory buckets.

  • :grant_read (String) —

    Allows grantee to list the objects in the bucket.

    This functionality is not supported for directory buckets.

  • :grant_read_acp (String) —

    Allows grantee to read the bucket ACL.

    This functionality is not supported for directory buckets.

  • :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.

    This functionality is not supported for directory buckets.

  • :grant_write_acp (String) —

    Allows grantee to write the ACL for the applicable bucket.

    This functionality is not supported for directory buckets.

  • :object_lock_enabled_for_bucket (Boolean) —

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

    This functionality is not supported for directory buckets.

  • :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 specify bucket owner full control ACLs (such as the predefined bucket-owner-full-control canned ACL or a custom ACL in XML format that grants the same permissions).

    By default, ObjectOwnership is set to BucketOwnerEnforced and ACLs are disabled. We recommend keeping ACLs disabled, except in uncommon use cases where you must control access for each object individually. For more information about S3 Object Ownership, see Controlling ownership of objects and disabling ACLs for your bucket in the Amazon S3 User Guide.

    This functionality is not supported for directory buckets. Directory buckets use the bucket owner enforced setting for S3 Object Ownership.

#delete_objects(options = {}) ⇒ Types::DeleteObjectsOutput

Examples:

Request syntax with placeholder values


bucket.delete_objects({
  delete: { # required
    objects: [ # required
      {
        key: "ObjectKey", # required
        version_id: "ObjectVersionId",
      },
    ],
    quiet: false,
  },
  mfa: "MFA",
  request_payer: "requester", # accepts requester
  bypass_governance_retention: false,
  expected_bucket_owner: "AccountId",
  checksum_algorithm: "CRC32", # accepts CRC32, CRC32C, SHA1, SHA256
})

Parameters:

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

    ({})

Options Hash (options):

  • :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.

    When performing the DeleteObjects operation on an MFA delete enabled bucket, which attempts to delete the specified versioned objects, you must include an MFA token. If you don't provide an MFA token, the entire request will fail, even if there are non-versioned objects that you are trying to delete. If you provide an invalid token, whether there are versioned object keys in the request or not, the entire Multi-Object Delete request will fail. For information about MFA Delete, see MFA Delete in the Amazon S3 User Guide.

    This functionality is not supported for directory buckets.

  • :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. If either the source or destination S3 bucket has Requester Pays enabled, the requester will pay for corresponding charges to copy the object. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide.

    This functionality is not supported for directory buckets.

  • :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.

    This functionality is not supported for directory buckets.

  • :expected_bucket_owner (String) —

    The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, 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 you use the SDK. This header will not provide any additional functionality if you don't use the SDK. When you send this header, there must be a corresponding x-amz-checksum-algorithm or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request.

    For the x-amz-checksum-algorithm header, replace algorithm with the supported algorithm from the following list:

    • CRC32

    • CRC32C

    • SHA1

    • SHA256

    For more information, see Checking object integrity in the Amazon S3 User Guide.

    If the individual checksum value you provide through x-amz-checksum-algorithm doesn't match the checksum algorithm you set through x-amz-sdk-checksum-algorithm, Amazon S3 ignores any provided ChecksumAlgorithm parameter and uses the checksum algorithm that matches the provided value in x-amz-checksum-algorithm.

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

#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",
  request_payer: "requester", # accepts requester
})

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.

    Directory buckets - For directory buckets, / is the only supported delimiter.

  • :encoding_type (String) —

    Requests Amazon S3 to encode the object keys in the response and specifies the encoding method to use. An object key can contain any Unicode character; however, the 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 multipart upload after which listing should begin.

    * General purpose buckets - For general purpose buckets, key-marker is an object key. 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.

    • Directory buckets - For directory buckets, key-marker is obfuscated and isn't a real object key. The upload-id-marker parameter isn't supported by directory buckets. To list the additional multipart uploads, you only need to set the value of key-marker to the NextKeyMarker value from the previous response.

      In the ListMultipartUploads response, the multipart uploads aren't sorted lexicographically based on the object keys.

  • :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 that you'd use a folder in a file system.)

    Directory buckets - For directory buckets, only prefixes that end in a delimiter (/) are supported.

  • :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.

    This functionality is not supported for directory buckets.

  • :expected_bucket_owner (String) —

    The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

  • :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. If either the source or destination S3 bucket has Requester Pays enabled, the requester will pay for corresponding charges to copy the object. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide.

    This functionality is not supported for directory buckets.

  version_id_marker: "VersionIdMarker",
  expected_bucket_owner: "AccountId",
  request_payer: "requester", # accepts requester
  optional_object_attributes: ["RestoreStatus"], # accepts RestoreStatus
})

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 can contain any Unicode character; however, the 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 that 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 account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

  • :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. If either the source or destination S3 bucket has Requester Pays enabled, the requester will pay for corresponding charges to copy the object. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide.

    This functionality is not supported for directory buckets.

  • :optional_object_attributes (Array<String>) —

    Specifies the optional fields that you want returned in the response. Fields that you do not specify are not returned.

  optional_object_attributes: ["RestoreStatus"], # accepts RestoreStatus
})

Parameters:

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

    ({})

Options Hash (options):

  • :delimiter (String) —

    A delimiter is a character that you use to group keys.

    * Directory buckets - For directory buckets, / is the only supported delimiter.

    • Directory buckets - When you query ListObjectsV2 with a delimiter during in-progress multipart uploads, the CommonPrefixes response parameter contains the prefixes that are associated with the in-progress multipart uploads. For more information about multipart uploads, see Multipart Upload Overview in the Amazon S3 User Guide.

  • :encoding_type (String) —

    Encoding type used by Amazon S3 to encode object keys in the response.

  • :prefix (String) —

    Limits the response to keys that begin with the specified prefix.

    Directory buckets - For directory buckets, only prefixes that end in a delimiter (/) are supported.

  • :fetch_owner (Boolean) —

    The owner field is not present in ListObjectsV2 by default. If you want to return the owner field with each key in the result, then set the FetchOwner field to true.

    Directory buckets - For directory buckets, the bucket owner is returned as the object owner for all objects.

  • :start_after (String) —

    StartAfter is where you want Amazon S3 to start listing from. Amazon S3 starts listing after this specified key. StartAfter can be any key in the bucket.

    This functionality is not supported for directory buckets.

  • :request_payer (String) —

    Confirms that the requester knows that she or he will be charged for the list objects request in V2 style. Bucket owners need not specify this parameter in their requests.

    This functionality is not supported for directory buckets.

  • :expected_bucket_owner (String) —

    The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

  • :optional_object_attributes (Array<String>) —

    Specifies the optional fields that you want returned in the response. Fields that you do not specify are not returned.

    This functionality is not supported for directory buckets.

Parameters:

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

    ({})

Options Hash (options):

  • :acl (String) —

    The canned ACL to apply to the object. For more information, see Canned ACL in the Amazon S3 User Guide.

    When adding a new object, you can use headers to grant ACL-based permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. By default, all objects are private. Only the owner has full access control. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API in the Amazon S3 User Guide.

    If the bucket that you're uploading objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don't specify an ACL or PUT requests that specify 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. PUT requests that contain other ACLs (for example, custom grants to certain Amazon Web Services accounts) fail and return a 400 error with the error code AccessControlListNotSupported. For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide.

    * This functionality is not supported for directory buckets.

    • This functionality is not supported for 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.

    The Content-MD5 header is required for any request to upload an object with a retention period configured using Amazon S3 Object Lock. For more information about Amazon S3 Object Lock, see Amazon S3 Object Lock Overview in the Amazon S3 User Guide.

    This functionality is not supported for directory buckets.

  • :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 you use the SDK. This header will not provide any additional functionality if you don't use the SDK. When you send this header, there must be a corresponding x-amz-checksum-algorithm or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request.

    For the x-amz-checksum-algorithm header, replace algorithm with the supported algorithm from the following list:

    • CRC32

    • CRC32C

    • SHA1

    • SHA256

    For more information, see Checking object integrity in the Amazon S3 User Guide.

    If the individual checksum value you provide through x-amz-checksum-algorithm doesn't match the checksum algorithm you set through x-amz-sdk-checksum-algorithm, Amazon S3 ignores any provided ChecksumAlgorithm parameter and uses the checksum algorithm that matches the provided value in x-amz-checksum-algorithm.

    For directory buckets, when you use Amazon Web Services SDKs, CRC32 is the default checksum algorithm that's used for performance.

  • :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 functionality is not supported for directory buckets.

    • This functionality is not supported for Amazon S3 on Outposts.

  • :grant_read (String) —

    Allows grantee to read the object data and its metadata.

    * This functionality is not supported for directory buckets.

    • This functionality is not supported for Amazon S3 on Outposts.

  • :grant_read_acp (String) —

    Allows grantee to read the object ACL.

    * This functionality is not supported for directory buckets.

    • This functionality is not supported for Amazon S3 on Outposts.

  • :grant_write_acp (String) —

    Allows grantee to write the ACL for the applicable object.

    * This functionality is not supported for directory buckets.

    • This functionality is not supported for 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 that was used when you store this object in Amazon S3 (for example, AES256, aws:kms, aws:kms:dsse).

    General purpose buckets - You have four mutually exclusive options to protect data using server-side encryption in Amazon S3, depending on how you choose to manage the encryption keys. Specifically, the encryption key options are Amazon S3 managed keys (SSE-S3), Amazon Web Services KMS keys (SSE-KMS or DSSE-KMS), and customer-provided keys (SSE-C). Amazon S3 encrypts data with server-side encryption by using Amazon S3 managed keys (SSE-S3) by default. You can optionally tell Amazon S3 to encrypt data at rest by using server-side encryption with other key options. For more information, see Using Server-Side Encryption in the Amazon S3 User Guide.

    Directory buckets - For directory buckets, only the server-side encryption with Amazon S3 managed keys (SSE-S3) (AES256) value is supported.

  • :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. For more information, see Storage Classes in the Amazon S3 User Guide.

    * For directory buckets, only the S3 Express One Zone storage class is supported to store newly created objects.

    • Amazon S3 on Outposts only uses the OUTPOSTS Storage Class.

  • :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 Amazon S3 User Guide.

    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 in the Amazon S3 User Guide.

    This functionality is not supported for directory buckets.

  • :sse_customer_algorithm (String) —

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

    This functionality is not supported for directory buckets.

  • :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.

    This functionality is not supported for directory buckets.

  • :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.

    This functionality is not supported for directory buckets.

  • :ssekms_key_id (String) —

    If x-amz-server-side-encryption has a valid value of aws:kms or aws:kms:dsse, this header specifies the ID (Key ID, Key ARN, or Key Alias) of the Key Management Service (KMS) symmetric encryption customer managed key that was used for the object. If you specify x-amz-server-side-encryption:aws:kms or x-amz-server-side-encryption:aws:kms:dsse, but do not provide x-amz-server-side-encryption-aws-kms-key-id, Amazon S3 uses the Amazon Web Services managed key (aws/s3) to protect the data. If the KMS key does not exist in the same account that's issuing the command, you must use the full ARN and not just the ID.

    This functionality is not supported for directory buckets.

  • :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. This value must be explicitly added during CopyObject operations.

    This functionality is not supported for directory buckets.

  • :bucket_key_enabled (Boolean) —

    Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using Key Management Service (KMS) keys (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.

    This functionality is not supported for directory buckets.

  • :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. If either the source or destination S3 bucket has Requester Pays enabled, the requester will pay for corresponding charges to copy the object. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide.

    This functionality is not supported for directory buckets.

  • :tagging (String) —

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

    This functionality is not supported for directory buckets.

  • :object_lock_mode (String) —

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

    This functionality is not supported for directory buckets.

  • :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.

    This functionality is not supported for directory buckets.

  • :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 in the Amazon S3 User Guide.

    This functionality is not supported for directory buckets.

  • :expected_bucket_owner (String) —

    The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

#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.
