props CfnLocationNFSProps — - resource properties.

Create a new AWS::DataSync::LocationNFS.

Construct Props

Name	Type	Description
onPremConfig	`IResolvable` `\|` `OnPremConfigProperty`	Contains a list of Amazon Resource Names (ARNs) of agents that are used to connect to an NFS server.
mountOptions?	`IResolvable` `\|` `MountOptionsProperty`	The NFS mount options that DataSync can use to mount your NFS share.
serverHostname?	`string`	The name of the NFS server.
subdirectory?	`string`	The subdirectory in the NFS file system that is used to read data from the NFS source location or write data to the NFS destination.
tags?	`CfnTag[]`	The key-value pair that represents the tag that you want to add to the location.

onPremConfig

Type: IResolvable | OnPremConfigProperty

Contains a list of Amazon Resource Names (ARNs) of agents that are used to connect to an NFS server.

If you are copying data to or from your AWS Snowcone device, see NFS Server on AWS Snowcone for more information.

mountOptions?

Type: IResolvable | MountOptionsProperty (optional)

The NFS mount options that DataSync can use to mount your NFS share.

serverHostname?

Type: string (optional)

The name of the NFS server.

This value is the IP address or Domain Name Service (DNS) name of the NFS server. An agent that is installed on-premises uses this hostname to mount the NFS server in a network.

If you are copying data to or from your AWS Snowcone device, see NFS Server on AWS Snowcone for more information.

This name must either be DNS-compliant or must be an IP version 4 (IPv4) address.

subdirectory?

Type: string (optional)

The subdirectory in the NFS file system that is used to read data from the NFS source location or write data to the NFS destination.

The NFS path should be a path that's exported by the NFS server, or a subdirectory of that path. The path should be such that it can be mounted by other NFS clients in your network.

To see all the paths exported by your NFS server, run " showmount -e nfs-server-name " from an NFS client that has access to your server. You can specify any directory that appears in the results, and any subdirectory of that directory. Ensure that the NFS export is accessible without Kerberos authentication.

To transfer all the data in the folder you specified, DataSync needs to have permissions to read all the data. To ensure this, either configure the NFS export with no_root_squash, or ensure that the permissions for all of the files that you want DataSync allow read access for all users. Doing either enables the agent to read the files. For the agent to access directories, you must additionally enable all execute access.

If you are copying data to or from your AWS Snowcone device, see NFS Server on AWS Snowcone for more information.

For information about NFS export configuration, see 18.7. The /etc/exports Configuration File in the Red Hat Enterprise Linux documentation.

tags?

Type: CfnTag[] (optional)

The key-value pair that represents the tag that you want to add to the location.

The value can be an empty string. We recommend using tags to name your resources.

addDeletionOverride(path)

public addDeletionOverride(path: string): void

Parameters

path string — The path of the value to delete.

Syntactic sugar for addOverride(path, undefined).

addDependsOn(target)

public addDependsOn(target: CfnResource): void

Parameters

target CfnResource

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

addMetadata(key, value)

public addMetadata(key: string, value: any): void

Parameters

key string
value any

Add a value to the CloudFormation Resource Metadata.

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)

addOverride(path, value)

public addOverride(path: string, value: any): void

Parameters

path string — - The path of the property, you can use dot notation to override values in complex types.
value any — - The value.

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with "Properties." (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example,

cfnResource.addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute']);
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE');

would add the overrides

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

addPropertyDeletionOverride(propertyPath)

public addPropertyDeletionOverride(propertyPath: string): void

Parameters

propertyPath string — The path to the property.

Adds an override that deletes the value of a property from the resource definition.

addPropertyOverride(propertyPath, value)

public addPropertyOverride(propertyPath: string, value: any): void

Parameters

propertyPath string — The path of the property.
value any — The value.

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

applyRemovalPolicy(policy?, options?)

public applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): void

Parameters

policy RemovalPolicy
options RemovalPolicyOptions

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

getAtt(attributeName)

public getAtt(attributeName: string): Reference

Parameters

attributeName string — The name of the attribute.

Returns

Reference

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

getMetadata(key)

public getMetadata(key: string): any

Parameters

key string

Returns

any

Retrieve a value value from the CloudFormation Resource Metadata.

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)

inspect(inspector)

public inspect(inspector: TreeInspector): void

Parameters

inspector TreeInspector — - tree inspector to collect and process attributes.

Examines the CloudFormation resource and discloses attributes.

overrideLogicalId(newLogicalId)

public overrideLogicalId(newLogicalId: string): void

Parameters

newLogicalId string — The new logical ID to use for this stack element.

Overrides the auto-generated logical ID with a specific ID.

toString()

public toString(): string

Returns

string

Returns a string representation of this construct.

protected renderProperties(props)

protected renderProperties(props: { [string]: any }): { [string]: any }

Parameters

props { [string]: any }

Returns

{ [string]: any }
