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](/sdk-for-ruby/v3/developer-guide/setup-config.html).

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

#initialize(options) ⇒ Client

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. This can be an 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`

    • The ‘:access_key_id`, `:secret_access_key`, and `:session_token` options.

    • ENV, ENV

    • ‘~/.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::InstanceProfileCredentails` or `Aws::ECSCredentials` to enable retries and extended timeouts. Instance profile credential fetching can be disabled by setting ENV to true.

  • :region (required, String) —

    The AWS region to connect to. The configured ‘:region` is used to determine the service `:endpoint`. When not passed, a default `:region` is searched for in the following locations:

This option is only used in the ‘legacy` retry mode.

  • :retry_max_delay (Integer) — default: 0 —

    The maximum number of seconds to delay between retries (0 for no limit) used by the default backoff function. This option is only used in the ‘legacy` retry mode.

    ** Please note ** When response stubbing is enabled, no HTTP requests are made, and retries are disabled.

  • :token_provider (Aws::TokenProvider) —

    A Bearer Token Provider. This can be an instance of any one of the following classes:

    • ‘Aws::StaticTokenProvider` - Used for configuring static, non-refreshing tokens.

    • ‘Aws::SSOTokenProvider` - Used for loading tokens from AWS SSO using an access token generated from `aws login`.

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.

<note markdown=“1”> 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*.

    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) —

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

Response structure

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*..

    [1]: docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebsapis-using-encryption.html

  • :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*.

    Valid values: ‘524288`

  • :progress (Integer) —

    The progress of the write process, as a percentage.

  • :checksum (required, String) —

    A Base64-encoded SHA256 checksum of the data. Only SHA256 checksums are supported.

  • :checksum_algorithm (required, String) —

#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.

<note markdown=“1”> 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*.
