describe-data-repository-associations

Description

Returns the description of specific Amazon FSx for Lustre or Amazon File Cache data repository associations, if one or more AssociationIds values are provided in the request, or if filters are used in the request. Data repository associations are supported only for Amazon FSx for Lustre file systems with the Persistent_2 deployment type and for Amazon File Cache resources.

You can use filters to narrow the response to include just data repository associations for specific file systems (use the file-system-id filter with the ID of the file system) or caches (use the file-cache-id filter with the ID of the cache), or data repository associations for a specific repository type (use the data-repository-type filter with a value of S3 or NFS ). If you don’t use filters, the response returns all data repository associations owned by your Amazon Web Services account in the Amazon Web Services Region of the endpoint that you’re calling.

When retrieving all data repository associations, you can paginate the response by using the optional MaxResults parameter to limit the number of data repository associations returned in a response. If more data repository associations remain, a NextToken value is returned in the response. In this case, send a later request with the NextToken request parameter set to the value of NextToken from the last response.

Options

--association-ids (list)

IDs of the data repository associations whose descriptions you want to retrieve (String).

(string)

Syntax:

"string" "string" ...

--filters (list)

A list of Filter elements.

(structure)

A filter used to restrict the results of describe calls. You can use multiple filters to return results that meet all applied filter requirements.

Name -> (string)

The name for this filter.

Values -> (list)

The values of the filter. These are all the values for any of the applied filters.

(string)

The value for a filter.

Shorthand Syntax:

Name=string,Values=string,string ...

JSON Syntax:

[
  {
    "Name": "file-system-id"|"backup-type"|"file-system-type"|"volume-id"|"data-repository-type"|"file-cache-id"|"file-cache-type",
    "Values": ["string", ...]
  }
  ...
]

--max-results (integer)

The maximum number of resources to return in the response. This value must be an integer greater than zero.

--next-token (string)

(Optional) Opaque pagination token returned from a previous operation (String). If present, this token indicates from what point you can continue processing the request, where the previous NextToken value left off.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

• json

• text

• table

• yaml

• yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

• on

• off

• auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

• base64

• raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Output

Associations -> (list)

An array of one or more data repository association descriptions.

(structure)

The configuration of a data repository association that links an Amazon FSx for Lustre file system to an Amazon S3 bucket or an Amazon File Cache resource to an Amazon S3 bucket or an NFS file system. The data repository association configuration object is returned in the response of the following operations:

• CreateDataRepositoryAssociation

• UpdateDataRepositoryAssociation

• DescribeDataRepositoryAssociations

Data repository associations are supported only for an Amazon FSx for Lustre file system with the Persistent_2 deployment type and for an Amazon File Cache resource.

AssociationId -> (string)

The system-generated, unique ID of the data repository association.

ResourceARN -> (string)

The Amazon Resource Name (ARN) for a given resource. ARNs uniquely identify Amazon Web Services resources. We require an ARN when you need to specify a resource unambiguously across all of Amazon Web Services. For more information, see Amazon Resource Names (ARNs) in the Amazon Web Services General Reference .

FileSystemId -> (string)

The globally unique ID of the file system, assigned by Amazon FSx.

Lifecycle -> (string)

Describes the state of a data repository association. The lifecycle can have the following values:

• CREATING - The data repository association between the file system or cache and the data repository is being created. The data repository is unavailable.

• AVAILABLE - The data repository association is available for use.

• MISCONFIGURED - The data repository association is misconfigured. Until the configuration is corrected, automatic import and automatic export will not work (only for Amazon FSx for Lustre).

• UPDATING - The data repository association is undergoing a customer initiated update that might affect its availability.

• DELETING - The data repository association is undergoing a customer initiated deletion.

• FAILED - The data repository association is in a terminal state that cannot be recovered.

FailureDetails -> (structure)

Provides detailed information about the data repository if its Lifecycle is set to MISCONFIGURED or FAILED .

Message -> (string)

A detailed error message.

FileSystemPath -> (string)

A path on the Amazon FSx for Lustre file system that points to a high-level directory (such as /ns1/ ) or subdirectory (such as /ns1/subdir/ ) that will be mapped 1-1 with DataRepositoryPath . The leading forward slash in the name is required. Two data repository associations cannot have overlapping file system paths. For example, if a data repository is associated with file system path /ns1/ , then you cannot link another data repository with file system path /ns1/ns2 .

This path specifies where in your file system files will be exported from or imported to. This file system directory can be linked to only one Amazon S3 bucket, and no other S3 bucket can be linked to the directory.

Note

If you specify only a forward slash (/ ) as the file system path, you can link only one data repository to the file system. You can only specify “/” as the file system path for the first data repository associated with a file system.

DataRepositoryPath -> (string)

The path to the data repository that will be linked to the cache or file system.

• For Amazon File Cache, the path can be an NFS data repository that will be linked to the cache. The path can be in one of two formats:

  • If you are not using the DataRepositorySubdirectories parameter, the path is to an NFS Export directory (or one of its subdirectories) in the format nsf://nfs-domain-name/exportpath . You can therefore link a single NFS Export to a single data repository association.

  • If you are using the DataRepositorySubdirectories parameter, the path is the domain name of the NFS file system in the format nfs://filer-domain-name , which indicates the root of the subdirectories specified with the DataRepositorySubdirectories parameter.

• For Amazon File Cache, the path can be an S3 bucket or prefix in the format s3://myBucket/myPrefix/ .

• For Amazon FSx for Lustre, the path can be an S3 bucket or prefix in the format s3://myBucket/myPrefix/ .

BatchImportMetaDataOnCreate -> (boolean)

A boolean flag indicating whether an import data repository task to import metadata should run after the data repository association is created. The task runs if this flag is set to true .

Note

BatchImportMetaDataOnCreate is not supported for data repositories linked to an Amazon File Cache resource.

ImportedFileChunkSize -> (integer)

For files imported from a data repository, this value determines the stripe count and maximum amount of data per file (in MiB) stored on a single physical disk. The maximum number of disks that a single file can be striped across is limited by the total number of disks that make up the file system or cache.

The default chunk size is 1,024 MiB (1 GiB) and can go as high as 512,000 MiB (500 GiB). Amazon S3 objects have a maximum size of 5 TB.

S3 -> (structure)

The configuration for an Amazon S3 data repository linked to an Amazon FSx for Lustre file system with a data repository association.

AutoImportPolicy -> (structure)

Specifies the type of updated objects (new, changed, deleted) that will be automatically imported from the linked S3 bucket to your file system.

Events -> (list)

The AutoImportPolicy can have the following event values:

• NEW - Amazon FSx automatically imports metadata of files added to the linked S3 bucket that do not currently exist in the FSx file system.

• CHANGED - Amazon FSx automatically updates file metadata and invalidates existing file content on the file system as files change in the data repository.

• DELETED - Amazon FSx automatically deletes files on the file system as corresponding files are deleted in the data repository.

You can define any combination of event types for your AutoImportPolicy .

(string)

AutoExportPolicy -> (structure)

Specifies the type of updated objects (new, changed, deleted) that will be automatically exported from your file system to the linked S3 bucket.

Events -> (list)

The AutoExportPolicy can have the following event values:

• NEW - New files and directories are automatically exported to the data repository as they are added to the file system.

• CHANGED - Changes to files and directories on the file system are automatically exported to the data repository.

• DELETED - Files and directories are automatically deleted on the data repository when they are deleted on the file system.

You can define any combination of event types for your AutoExportPolicy .

(string)

Tags -> (list)

A list of Tag values, with a maximum of 50 elements.

(structure)

Specifies a key-value pair for a resource tag.

Key -> (string)

A value that specifies the TagKey , the name of the tag. Tag keys must be unique for the resource to which they are attached.

Value -> (string)

A value that specifies the TagValue , the value assigned to the corresponding tag key. Tag values can be null and don’t have to be unique in a tag set. For example, you can have a key-value pair in a tag set of finances : April and also of payroll : April .

CreationTime -> (timestamp)

The time that the resource was created, in seconds (since 1970-01-01T00:00:00Z), also known as Unix time.

FileCacheId -> (string)

The globally unique ID of the Amazon File Cache resource.

FileCachePath -> (string)

A path on the Amazon File Cache that points to a high-level directory (such as /ns1/ ) or subdirectory (such as /ns1/subdir/ ) that will be mapped 1-1 with DataRepositoryPath . The leading forward slash in the path is required. Two data repository associations cannot have overlapping cache paths. For example, if a data repository is associated with cache path /ns1/ , then you cannot link another data repository with cache path /ns1/ns2 .

This path specifies the directory in your cache where files will be exported from. This cache directory can be linked to only one data repository (S3 or NFS) and no other data repository can be linked to the directory.

Note

The cache path can only be set to root (/) on an NFS DRA when DataRepositorySubdirectories is specified. If you specify root (/) as the cache path, you can create only one DRA on the cache.

The cache path cannot be set to root (/) for an S3 DRA.

DataRepositorySubdirectories -> (list)

For Amazon File Cache, a list of NFS Exports that will be linked with an NFS data repository association. All the subdirectories must be on a single NFS file system. The Export paths are in the format /exportpath1 . To use this parameter, you must configure DataRepositoryPath as the domain name of the NFS file system. The NFS file system domain name in effect is the root of the subdirectories. Note that DataRepositorySubdirectories is not supported for S3 data repositories.

(string)

NFS -> (structure)

The configuration for an NFS data repository linked to an Amazon File Cache resource with a data repository association.

Version -> (string)

The version of the NFS (Network File System) protocol of the NFS data repository. Currently, the only supported value is NFS3 , which indicates that the data repository must support the NFSv3 protocol.

DnsIps -> (list)

A list of up to 2 IP addresses of DNS servers used to resolve the NFS file system domain name. The provided IP addresses can either be the IP addresses of a DNS forwarder or resolver that the customer manages and runs inside the customer VPC, or the IP addresses of the on-premises DNS servers.

(string)

AutoExportPolicy -> (structure)

This parameter is not supported for Amazon File Cache.

Events -> (list)

The AutoExportPolicy can have the following event values:

• NEW - New files and directories are automatically exported to the data repository as they are added to the file system.

• CHANGED - Changes to files and directories on the file system are automatically exported to the data repository.

• DELETED - Files and directories are automatically deleted on the data repository when they are deleted on the file system.

You can define any combination of event types for your AutoExportPolicy .

(string)

NextToken -> (string)

(Optional) Opaque pagination token returned from a previous operation (String). If present, this token indicates from what point you can continue processing the request, where the previous NextToken value left off.
