## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_codebuild as codebuild } from 'aws-cdk-lib';
const projectFileSystemLocationProperty: codebuild.CfnProject.ProjectFileSystemLocationProperty = {
  identifier: 'identifier',
  location: 'location',
  mountPoint: 'mountPoint',
  type: 'type',

  // the properties below are optional
  mountOptions: 'mountOptions',
};
```

## Properties

- `identifier`: string (required) — 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.

- `location`: string (required) — 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.

- `mountOptions`: string — 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) .

- `mountPoint`: string (required) — The location in the container where you mount the file system.

- `type`: string (required) — The type of the file system.

  The one supported type is `EFS` .
