MountableFsxLustre

class aws_rfdk.MountableFsxLustre(scope, *, filesystem, extra_mount_options=None, fileset=None)

Bases: object

This class encapsulates scripting that can be used to mount an Amazon FSx for Lustre File System onto an instance.

Security Considerations

• Using this construct on an instance will result in that instance dynamically downloading and running scripts from your CDK bootstrap bucket when that instance is launched. You must limit write access to your CDK bootstrap bucket to prevent an attacker from modifying the actions performed by these scripts. We strongly recommend that you either enable Amazon S3 server access logging on your CDK bootstrap bucket, or enable AWS CloudTrail on your account to assist in post-incident analysis of compromised production environments.

Parameters

• scope (Construct) –

• filesystem (LustreFileSystem) – The {@link https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-fsx.LustreFileSystem.htmlFSx for Lustre} filesystem that will be mounted by the object.

• extra_mount_options (Optional[Sequence[str]]) – Extra Lustre mount options that will be added to /etc/fstab for the file system. See: {@link http://manpages.ubuntu.com/manpages/precise/man8/mount.lustre.8.html}. The given values will be joined together into a single string by commas. ex: [‘soft’, ‘rsize=4096’] will become ‘soft,rsize=4096’ Default: No extra options.

• fileset (Optional[str]) – The fileset to mount. Default: Mounts the root of the filesystem.

Methods

mount_to_linux_instance(target, *, location, permissions=None)

Mount the filesystem to the given instance at instance startup.

This is accomplished by adding scripting to the UserData of the instance to mount the filesystem on startup. If required, the instance’s security group is granted ingress to the filesystem’s security group on the required ports.

Parameters

• target (IMountingInstance) –

• location (str) – Directory for the mount point.

• permissions (Optional[MountPermissions]) – File permissions for the mounted filesystem. Default: MountPermissions.READWRITE

Return type

None

uses_user_posix_permissions()

Returns whether the mounted file-system evaluates the UID/GID of the system user accessing the file-system.

Some network file-systems provide features to fix a UID/GID for all access to the mounted file-system and ignore the system user accessing the file. If this is the case, an implementing class must indicate this in the return value.
