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.

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`, `:session_token`, and `:account_id` options.

    • ENV, ENV, ENV, and 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::InstanceProfileCredentials` 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:

  snapshot_id: "SnapshotId", # required
  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*..

    [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*.

  • :data_length (required, Integer) —

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

    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) —

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

  req.send_request(options)
end

#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*.
