## Properties
<a name="aws-properties-codebuild-project-projectfilesystemlocation-properties"></a>

`Identifier`  <a name="cfn-codebuild-project-projectfilesystemlocation-identifier"></a>
The name used to access a file system created by Amazon EFS. CodeBuild creates an environment variable by appending the `identifier` in all capital letters to `CODEBUILD_`. For example, if you specify `my_efs` for `identifier`, a new environment variable is create named `CODEBUILD_MY_EFS`.   
 The `identifier` is used to mount your file system.   
*Required*: Yes  
*Type*: String  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`Location`  <a name="cfn-codebuild-project-projectfilesystemlocation-location"></a>
A string that specifies the location of the file system created by Amazon EFS. Its format is `efs-dns-name:/directory-path`. You can find the DNS name of file system when you view it in the Amazon EFS console. The directory path is a path to a directory in the file system that CodeBuild mounts. For example, if the DNS name of a file system is `fs-abcd1234.efs.us-west-2.amazonaws.com`, and its mount directory is `my-efs-mount-directory`, then the `location` is `fs-abcd1234.efs.us-west-2.amazonaws.com:/my-efs-mount-directory`.   
The directory path in the format `efs-dns-name:/directory-path` is optional. If you do not specify a directory path, the location is only the DNS name and CodeBuild mounts the entire file system.   
*Required*: Yes  
*Type*: String  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`MountOptions`  <a name="cfn-codebuild-project-projectfilesystemlocation-mountoptions"></a>
 The mount options for a file system created by Amazon EFS. The default mount options used by CodeBuild are `nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2`. For more information, see [Recommended NFS Mount Options](https://docs.aws.amazon.com/efs/latest/ug/mounting-fs-nfs-mount-settings.html).   
*Required*: No  
*Type*: String  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`MountPoint`  <a name="cfn-codebuild-project-projectfilesystemlocation-mountpoint"></a>
The location in the container where you mount the file system.   
*Required*: Yes  
*Type*: String  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`Type`  <a name="cfn-codebuild-project-projectfilesystemlocation-type"></a>
 The type of the file system. The one supported type is `EFS`.   
*Required*: Yes  
*Type*: String  
*Allowed values*: `EFS`  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
