AWS::DataSync::LocationNFS
The AWS::DataSync::LocationNFS
resource specifies a file system on a
Network File System (NFS) server that can be read from or written to.
Syntax
To declare this entity in your Amazon CloudFormation template, use the following syntax:
JSON
{ "Type" : "AWS::DataSync::LocationNFS", "Properties" : { "MountOptions" :
MountOptions
, "OnPremConfig" :OnPremConfig
, "ServerHostname" :String
, "Subdirectory" :String
, "Tags" :[ Tag, ... ]
} }
YAML
Type: AWS::DataSync::LocationNFS Properties: MountOptions:

ServerHostname:String
Subdirectory:String
Tags:- Tag
Properties
MountOptions
-
The NFS mount options that DataSync can use to mount your NFS share.
Required: No
Type: MountOptions
Update requires: No interruption
OnPremConfig
-
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 Amazon Snowcone device, see NFS Server on Amazon Snowcone for more information.
Required: Yes
Type: OnPremConfig
Update requires: No interruption
ServerHostname
-
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 Amazon Snowcone device, see NFS Server on Amazon Snowcone for more information.
Note This name must either be DNS-compliant or must be an IP version 4 (IPv4) address.
Required: No
Type: String
Maximum:
255
Pattern:
^(([a-zA-Z0-9\-]*[a-zA-Z0-9])\.)*([A-Za-z0-9\-]*[A-Za-z0-9])$
Update requires: Replacement
Subdirectory
-
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 Amazon Snowcone device, see NFS Server on Amazon 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. Required: No
Type: String
Maximum:
4096
Pattern:
^[a-zA-Z0-9_\-\+\./\(\)\p{Zs}]+$
Update requires: No interruption
Tags
-
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.
Required: No
Type: List of Tag
Maximum:
50
Update requires: No interruption
Return values
Ref
When you pass the logical ID of this resource to the intrinsic Ref
function, Ref
returns the location resource ARN. For example:
arn:aws:datasync:us-east-2:111222333444:location/loc-07db7abfc326c50s3
For more information about using the Ref
function, see Ref.
Fn::GetAtt
The Fn::GetAtt
intrinsic function returns a value for a specified attribute
of this type. The following are the available attributes and sample return values.
For more information about using the Fn::GetAtt
intrinsic function, see
Fn::GetAtt.
Examples
Create a NFS location for DataSync
The following example specifies an NFS location for DataSync, using a source and
destination location. In this example, the server hostname is
MyServer@example.com
, using NFS version 4.0, in the subdirectory
/MySubdirectory
.
