Overview

An API client for EBS. To construct a client, you need to configure a :region and :credentials.

client = Aws::EBS::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

For details on configuring region and credentials see the developer guide.

See #initialize for a full list of supported configuration options.

Returns a new instance of Client.

Parameters:

  • options (Hash)

Options Hash (options):

  • :plugins (Array<Seahorse::Client::Plugin>) — default: []] —

    A list of plugins to apply to the client. Each plugin is either a class name or an instance of a plugin class.

  • :credentials (required, Aws::CredentialProvider) —

    Your AWS credentials used for authentication. This can be any class that includes and implements Aws::CredentialProvider, or instance of any one of the following classes:

    • Aws::Credentials - Used for configuring static, non-refreshing credentials.

    • Aws::SharedCredentials - Used for loading static credentials from a shared file, such as ~/.aws/config.

    • Aws::AssumeRoleCredentials - Used when you need to assume a role.

    • Aws::AssumeRoleWebIdentityCredentials - Used when you need to assume a role after providing credentials via the web.

    • Aws::SSOCredentials - Used for loading credentials from AWS SSO using an access token generated from aws login.

    • Aws::ProcessCredentials - Used for loading credentials from a process that outputs to stdout.

    • Aws::InstanceProfileCredentials - Used for loading credentials from an EC2 IMDS on an EC2 instance.

    • Aws::ECSCredentials - Used for loading credentials from instances running in ECS.

    • Aws::CognitoIdentityCredentials - Used for loading credentials from the Cognito Identity service.

    When :credentials are not configured directly, the following locations will be searched for credentials:

    • Aws.config[:credentials]

    • The :access_key_id, :secret_access_key, :session_token, and :account_id options.

    • ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY'], ENV['AWS_SESSION_TOKEN'], and ENV['AWS_ACCOUNT_ID'].

    • ~/.aws/credentials

    • ~/.aws/config

    • EC2/ECS IMDS instance profile - When used by default, the timeouts are very aggressive. Construct and pass an instance of Aws::InstanceProfileCredentials or Aws::ECSCredentials to enable retries and extended timeouts. Instance profile credential fetching can be disabled by setting ENV['AWS_EC2_METADATA_DISABLED'] to true.

Instance Method Details

#complete_snapshot(params = {}) ⇒ Types::CompleteSnapshotResponse

Seals and completes the snapshot after all of the required blocks of data have been written to it. Completing the snapshot changes the status to completed. You cannot write new blocks to a snapshot after it has been completed.

You should always retry requests that receive server (5xx) error responses, and ThrottlingException and RequestThrottledException client error responses. For more information see Error retries in the Amazon Elastic Compute Cloud User Guide.

Examples:

Request syntax with placeholder values


resp = client.complete_snapshot({
  snapshot_id: "SnapshotId", # required
  changed_blocks_count: 1, # required
  checksum: "Checksum",
  checksum_algorithm: "SHA256", # accepts SHA256
  checksum_aggregation_method: "LINEAR", # accepts LINEAR
})

Response structure

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :snapshot_id (required, String) —

    The ID of the snapshot.

  • :changed_blocks_count (required, Integer) —

    The number of blocks that were written to the snapshot.

  • :checksum (String) —

    An aggregated Base-64 SHA256 checksum based on the checksums of each written block.

    To generate the aggregated checksum using the linear aggregation method, arrange the checksums for each written block in ascending order of their block index, concatenate them to form a single string, and then generate the checksum on the entire string using the SHA256 algorithm.

  • :checksum_algorithm (String) —

    The algorithm used to generate the checksum. Currently, the only supported algorithm is SHA256.

#put_snapshot_block(params = {}) ⇒ Types::PutSnapshotBlockResponse

Writes a block of data to a snapshot. If the specified block contains data, the existing data is overwritten. The target snapshot must be in the pending state.

Data written to a snapshot must be aligned with 512-KiB sectors.

You should always retry requests that receive server (5xx) error responses, and ThrottlingException and RequestThrottledException client error responses. For more information see Error retries in the Amazon Elastic Compute Cloud User Guide.

Examples:

  block_index: 1, # required
  block_data: "data", # required
  data_length: 1, # required
  progress: 1,
  checksum: "Checksum", # required
  checksum_algorithm: "SHA256", # required, accepts SHA256
})

Response structure


resp.checksum #=> String
resp.checksum_algorithm #=> String, one of "SHA256"

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :snapshot_id (required, String) —

    The ID of the snapshot.

    If the specified snapshot is encrypted, you must have permission to use the KMS key that was used to encrypt the snapshot. For more information, see Using encryption in the Amazon Elastic Compute Cloud User Guide..

  • :block_index (required, Integer) —

    The block index of the block in which to write the data. A block index is a logical index in units of 512 KiB blocks. To identify the block index, divide the logical offset of the data in the logical volume by the block size (logical offset of data/524288). The logical offset of the data must be 512 KiB aligned.

  • :block_data (required, String, IO) —

    The data to write to the block.

    The block data is not signed as part of the Signature Version 4 signing process. As a result, you must generate and provide a Base64-encoded SHA256 checksum for the block data using the x-amz-Checksum header. Also, you must specify the checksum algorithm using the x-amz-Checksum-Algorithm header. The checksum that you provide is part of the Signature Version 4 signing process. It is validated against a checksum generated by Amazon EBS to ensure the validity and authenticity of the data. If the checksums do not correspond, the request fails. For more information, see Using checksums with the EBS direct APIs in the Amazon Elastic Compute Cloud User Guide.

  • :data_length (required, Integer) —

    The size of the data to write to the block, in bytes. Currently, the only supported size is 524288 bytes.

#start_snapshot(params = {}) ⇒ Types::StartSnapshotResponse

Creates a new Amazon EBS snapshot. The new snapshot enters the pending state after the request completes.

After creating the snapshot, use PutSnapshotBlock to write blocks of data to the snapshot.

You should always retry requests that receive server (5xx) error responses, and ThrottlingException and RequestThrottledException client error responses. For more information see Error retries in the Amazon Elastic Compute Cloud User Guide.

Examples:

Request syntax with placeholder values


resp = client.start_snapshot({
  volume_size: 1, # required
  parent_snapshot_id: "SnapshotId",
  tags: [
    {
      key: "TagKey",
      value: "TagValue",
    },
  ],
  description: "Description",
  client_token: "IdempotencyToken",
  encrypted: false,
  kms_key_arn: "KmsKeyArn",
  timeout: 1,
})

Response structure


resp.description #=> String
resp.snapshot_id #=> String
resp.owner_id #=> String
resp.status #=> String, one of "completed", "pending", "error"
resp.start_time #=> Time
resp.volume_size #=> Integer
resp.block_size #=> Integer
resp.tags #=> Array
resp.tags[0].key #=> String
resp.tags[0].value #=> String
resp.parent_snapshot_id #=> String
resp.kms_key_arn #=> String
resp.sse_type #=> String, one of "sse-ebs", "sse-kms", "none"

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :volume_size (required, Integer) —

    The size of the volume, in GiB. The maximum size is 65536 GiB (64 TiB).

  • :parent_snapshot_id (String) —

    The ID of the parent snapshot. If there is no parent snapshot, or if you are creating the first snapshot for an on-premises volume, omit this parameter.

    You can't specify ParentSnapshotId and Encrypted in the same request. If you specify both parameters, the request fails with ValidationException.

    The encryption status of the snapshot depends on the values that you specify for Encrypted, KmsKeyArn, and ParentSnapshotId, and whether your Amazon Web Services account is enabled for encryption by default. For more information, see Using encryption in the Amazon Elastic Compute Cloud User Guide.

    If you specify an encrypted parent snapshot, you must have permission to use the KMS key that was used to encrypt the parent snapshot. For more information, see Permissions to use Key Management Service keys in the Amazon Elastic Compute Cloud User Guide.

  • :tags (Array<Types::Tag>) —

    The tags to apply to the snapshot.

  • :description (String) —

    A description for the snapshot.

  • :client_token (String) —

    A unique, case-sensitive identifier that you provide to ensure the idempotency of the request. Idempotency ensures that an API request completes only once. With an idempotent request, if the original request completes successfully. The subsequent retries with the same client token return the result from the original successful request and they have no additional effect.

    If you do not specify a client token, one is automatically generated by the Amazon Web Services SDK.

    For more information, see Idempotency for StartSnapshot API in the Amazon Elastic Compute Cloud User Guide.

    A suitable default value is auto-generated. You should normally not need to pass this option.**

  • :encrypted (Boolean) —

    Indicates whether to encrypt the snapshot.

    You can't specify Encrypted and ParentSnapshotId in the same request. If you specify both parameters, the request fails with ValidationException.

    The encryption status of the snapshot depends on the values that you specify for Encrypted, KmsKeyArn, and ParentSnapshotId, and whether your Amazon Web Services account is enabled for encryption by default. For more information, see Using encryption in the Amazon Elastic Compute Cloud User Guide.

    To create an encrypted snapshot, you must have permission to use the KMS key. For more information, see Permissions to use Key Management Service keys in the Amazon Elastic Compute Cloud User Guide.

  • :kms_key_arn (String) —

    The Amazon Resource Name (ARN) of the Key Management Service (KMS) key to be used to encrypt the snapshot.

    The encryption status of the snapshot depends on the values that you specify for Encrypted, KmsKeyArn, and ParentSnapshotId, and whether your Amazon Web Services account is enabled for encryption by default. For more information, see Using encryption in the Amazon Elastic Compute Cloud User Guide.

    To create an encrypted snapshot, you must have permission to use the KMS key. For more information, see Permissions to use Key Management Service keys in the Amazon Elastic Compute Cloud User Guide.

  • :timeout (Integer) —

    The amount of time (in minutes) after which the snapshot is automatically cancelled if:

    • No blocks are written to the snapshot.

    • The snapshot is not completed after writing the last block of data.

    If no value is specified, the timeout defaults to 60 minutes.

Returns:
