Deploying the Foldr server in Azure

The Foldr server can be run on-premise or in various cloud platforms, such as Microsoft Azure as a virtual machine.  Virtual machines in Azure use the .vhd and .vhdx Hyper-V disk format.

Download the latest file using the link provided by Foldr support and extract this to a suitable location on the local machine.

Deploying Foldr in Azure

First, log into the Microsoft Azure portal at with a suitable administrative account

Create the Storage Account (v2)

Create a storage account if one does not already exist by creating the resource from the Azure portal home screen.  If a suitable storage account already exists, skip to upload image section.

Click Create a resource

Click Create

Complete the create Storage Account screen, selecting a suitable Subscription and Resource Group.  Give the instance a name, and select a geographic region that applies to your deployment.  Other options regarding redundancy, performance and networking can be configured as required.  The default values are acceptable.

Click Review + Create

A validation passed notification should be displayed.

Click Create

A deployment in progress prompt will be displayed.  After several minutes the storage account will be ready.

Once complete, click Go to Resource

Make a note of the Storage account name in the Overview panel.  This will required later when the Foldr image is uploaded.

Create an access key by clicking Access Keys in the left hand panel

Then, click Show Keys.

Copy the value displayed from Key 1.  This will be required in the next step.

Upload the Foldr VHD and Create Image

Azure requires the virtual hard disk to be fixed in size rather than thin provisioned / dynamic.   You can use alternative methods to upload to Azure using native MS PowerShell commands or other tools, but in this case the full 100GB VM disk  would need to be uploaded, which is an unnecessary waste of bandwidth/time.   As such we recommend using a third-party tool below to upload the image to Azure, only 6GB will be uploaded and the rest of the empty space on disk is not included.

– Download Go from for your platform and install the application.  Windows screenshots will be shown in this example.

Once installed, open a command prompt (or macOS Terminal) and run the command:

Windows:go install[email protected]

macOS:go get

Next, with the foldr.vhd file accessible on the local machine, use the following command to upload it to the Azure Storage Account

azure-vhd-utils upload --localvhdpath /path/to/foldrv4.vhd --stgaccountname <storage-account-name> --stgaccountkey "<account-key>" --blobname foldrv4.vhd

Replacing <storage-account-name> and <account-key> as required.

It will compute the MD5 checksum, before proceeding with the upload:

Once the upload has completed, go to the Azure portal home screen > All Services > Images.  Click + Create

In the Create an Image screen, give the Instance a name and select a suitable Subscription, Resource Group and Region.

Select the OS type as Linux, Generation 1 and click Browse to navigate to the Storage blob (foldrv4.vhd)

Select the Storage account and select foldrv4.vhd uploaded earlier

Click Select and then Review + create

The Image will be deployed.  Once complete, click Go to resource (alternatively, go to Azure > All Services > Images and select the image just created)

Create the Virtual Machine

From the Azure > Images panel (and selecting the image just created) – Click + Create VM

Complete the New Virtual Machine options, giving the VM a suitable name and selecting Subscription, Resource Group, VM Size (2vCPU and 4GB RAM recommended – if a VM type of less than 2GB RAM is selected, it will result in the web server service in the Foldr VM failing to start correctly).

Note – The authentication type may be SSH public key, or password may be used – create a username and password if the latter option is used.

Select suitable disk type/performace required (standard HDD is fine, but you may require the additional performance of SSD)

On the Networking tab, create a new virtual security group.  Select Advanced > Create New

The following network ports (TCP) should be configured INBOUND

TCP 80 – HTTP – This is optional, but recommended.  Users sessions are automatically redirected to HTTPS, but opening HTTP inbound will enable the use of Let’s Encrypt fully validated SSL certificates at no charge.
TCP 443 – HTTPS (user sessions)
TCP 30537 – HTTPS custom port for Foldr Settings (web admin)

If SSH access is required, TCP 2082 should also be permitted

Once you confirm the selection, a summary window will be displayed, click Create

After a few moments the VM will be created and accessible under Azure > All Services > Virtual Machines.  Click the virutal machine and its public IP address will be visible

The first time Foldr is powered on, it will go through an initial setup routione and after a few minutes it should be reachable at its public IP address

The Foldr server can now be configured and a suitable public DNS A/host record should be created and an SSL certificate installed, either using the Let’s Encrypt service (at no cost), or a paid-for certificate from a recognised certificate authority.
