Filesystem Resource¶

A Filesystem connection is a set of connection parameters needed to perform download/upload operations using a remote file location.

This connection can be stored in two ways:

related to the object which is going to use it (Custom source option)
as a Rulex Platform Resource of Filesystem type (Saved source option), which can be used at any time and in any operation.

If this connection is stored as a Filesystem resource, the user can define a set of permissions linked to this resource (as explained in the permissions page) to limit/control the access other users can have on the inserted connection.

To use a Filesystem resource in any panel, a filesystem connection is required, and the user must have view permissions set to allow on the resource itself, while modify permissions are required to see its internal parameters.

Tip

By creating a Filesystem resource with view permissions for all users and modify permission only for the administrator, you are exposing a connection without sharing username and password used in the authentication procedure.

Filesystem connection configuration¶

Rulex Platform supports the following remote locations:

ShareDrive File System
HTTP/S Server
FTP/S Server
Amazon AWS S3
Microsoft SharePoint
Hadoop HDFS File System
Azure Blob Storage
SFTP/S Server
Google Drive
Microsoft Outlook

The configuration interface and its parameters vary for every filesystem type. Further details are listed in the paragraphs below.

Note

The Local Filesystem file location is considered as a filesystem, and it corresponds to the client machine disk. As this filesystem doesn’t require any connection parameter, it is available only as a Custom connection. To use the Local Filesystem in Rulex Platform Cloud/server version, you can find more information in this note.

Warning

Rulex’s technical documentation does not and cannot provide comprehensive guidelines on the use, limitations and constraints of third-party software programs, beyond how Rulex integrates with this software.

Please read the technical documentation of the third-party software itself for up-to-date information.

Creating a Filesystem Resource¶

To create a Filesystem resource, you need to open the Explorer panel (for more information refer to the corresponding page) and follow the procedure below:

Procedure

Click the Explore Resources icon to open the Explorer panel.
Deactivate the primary resource filter by toggling off on the Primary filter on the upper right side of the Explorer panel to add general resources.
Hover the mouse over the Plus button.
Select Add new Filesystem and a dedicated window will appear on the screen.
Select the Filesystem type you want to connect to (see supported types).
Configure the connection parameters following the provided guide. A test connection will be performed; if unsuccessful, an error message is displayed, offering also the opportunity to continue working anyway.
Type a unique name for the new resource.
Click Create: the new Filesystem resource is now added to the list.

Once the Filesystem resource is defined, it can be referred as a Saved source in any location where a remote connection can be used.

As an example, you’ll find below the most important Filesystem saved connection applications:

In any of the applications listed above, it is still possible to define the connection while performing the operation itself, by inserting a Custom connection in the parameters of the section above.

Proxy panel¶

Sometimes, for standalone installation, the used network needs to be protected with proxy firewall or by using a security VPN. Usually, the Rulex Platform software inherits proxy configuration directly from the system but when this does not occur (for example with some VPNs which enforce the proxy directly on the connection and not on the entire operating system), the proxy configuration needs to be imposed on the external connection itself. This can be done by using the Proxy panel which is contained in any filesystem remote connection configuration pane.

To open the Proxy panel you can click on the Change settings button located at the bottom of any remote connection configuration pane.

The Proxy panel is composed by four different entries:

Host: the IP host of the proxy.
Port: the IP port of the proxy.
Username: for secured proxy the username to be used in the proxy bypass.
Password: for secured proxy the password to be used in the proxy bypass.

Authentication application mediated¶

Rulex Platform connectors need to be executed without the physical presence of the user for the majority of the computation time. Moreover, if an interactive authentication is required, this should be asked once even if used for several connections.

The general approach of the majority of the identity providers available now on the market is to use a client credential authentication flow which exploits a constructed application to manage a machine to machine connection.

This definition of these client applications has to be executed on the identity provider portal (Azure, Google for example) towards you want to connect to.

Note

The Rulex Platform filesystem remote connections which now require a client application definition are:

Sharepoint connector with Azure authentication
Outlook connector
Google connector

Please refer to the official documentation of these providers for the complete step-by-step guide of this client creation. Here and in the correlated pages the attention is concentrated about most critical configuration steps or about the use of the already created application within the Rulex Platform filesystem configuration.

Sharepoint Azure authentication connection requires an Azure authentication app with on behalf as the user rights. Step-by-step guide to create this type of application with the correct rights to access the desired Sharepoint sites and the way to obtain the necessary signed JWT to be used in Rulex Platform is described in this side page.

Outlook connection requires an Azure authentication app with delegated permission on the desired user. The application needs the following permissions on Microsoft Graph service:

User.Read - Sign in and read user profile
Mail.Read - Read user mail
Mail.ReadWrite - Read and write access to user mail (only used in export operations)
Mail.Send - Send mail as a user (only used in export operations)

A step-by-step guide to create this type of application with the correct rights and the way to obtain the necessary information to configure the corresponding panel in Rulex Platform is available in this dedicated page.

Google connection requires a Google authentication app acting with delegated permission on the desired drive user storage. Please refer to this link, for a general guide about Oauth2 app authentication in the Google framework.
