Azure Prerequisites
All things considered, the install via Azure Marketplace should only take an hour at most. All KNIME Business Hub Azure Marketplace offerings are designed as single Azure VM images containing all software requirements - thus, the admin will not need to access the instance’s OS during the install process.
The person responsible for the deployment of KNIME Business Hub via the Azure marketplace should be familiar with basic Azure functionality surrounding configuring Azure VM instances and should have relevant permissions to initiate said instances. For additional information on internal Business Hub administration, refer to the KNIME Business Hub Admin Guide.
If you are provisioning a Business Hub - BYOL Edition instance, you will need a license key. To obtain a license key, please contact KNIME Customer Care. If you are installing a Business Hub on Azure without the use of KNIME’s Azure VM Images, refer to the KNIME Business Hub Installation Guide.
Azure Roles and Policies
To deploy a KNIME Business Hub VM, the user will be required to have the Azure roles/policies that allow access to launch Azure VM instances and manage disk volumes. Further rights may be needed to create security groups and Virtual Networks if they are not already created. The application does not require the use of Azure account root privileges.
KNIME Azure VM Images do not generate any Azure roles and policies for KNIME Business Hub nor do they grant public access to any resources. Users can generate the Azure role for the Azure VM instance of KNIME Business Hub with necessary access based on their use cases (e.g. Azure Blob Storage access).
| For more information on Azure-recommended access security and policy of least privilege, refer to the Azure Identity & Access Security Best Practices article. |
Networking
It is assumed that a Virtual Network with internet access is configured and available. For additional information on networking requirements, refer to the Networking prerequisites section of the installation guide.
Solution Architecture
All KNIME Business Hub Marketplace offerings are composed of a Kubernetes cluster initiated and contained on a single machine in a single subnet of a VPC. Use of an elastic IP is preferred for this initial machine since it simplifies the update/upgrade procedure. For more information on how to link other compute resources to a Kubernetes cluster, refer to the Kubernetes documentation.
Keys and secrets
An SSH key for access to the KNIME Business Hub instance is created or chosen via the Azure Management Console or CLI at instance launch. The admin is responsible for managing this key as per the recommendations set within their organization.
Deployment of the solution does not require creation or management of any stored secrets.
Azure Deployment Guide
This section will go through the following processes:
-
Provision your chosen KNIME Business Hub Azure VM Image
-
Connect to the KNIME Business Hub Admin Console

Basics
Upon choosing the VM Image, click see all images. This will take you to the Azure marketplace. Search for “KNIME” and pick the desired offering.
| Only the images from vendor KNIME are maintained by us. |
Once you have chosen the desired offering, choose a Size. We recommend picking a size under the Recommended by image publisher group. For more information on how to properly estimate the size needed, refer to the Hardware Requirements section of the Business Hub Installation Guide.
For authentication type, pick SSH public key. Either use an existing key or create your own. This key will be used for ssh access to the machine and should be recycled according to your organization’s IT security protocols.
Disks
By default, one 512 GB SSD volume is included as a recommended minimum. The installer can increase the size of this volume or add additional if they see fit. By default, these drives are not encrypted. All customer-created data and assets will be stored on this drive.
For more information on storage size estimations, refer to the Hardware Requirements section of the Business Hub Installation Guide.
Networking
Here, you will configure the desired Virtual Networking for the instance. Make sure to place the instance in a network that has access to the internet. By default, the instance will create and apply a new security group with the following ports open:
-
80 (HTTP)
-
443 (HTTPS)
-
22 (SSH - ADMIN USE ONLY)
-
6443 (kubectl - ADMIN USE ONLY)
-
8800 (KOTS Admin Console - ADMIN USE ONLY)
| This default security group opens the above ports for all IPs. It is recommended the admin adjust these values to adhere with their organization’s security best practices. |
Review and Create
Review the values and click Create. This will start the initial provisioning and setup of the KNIME Business Hub. This process should take at most 30 minutes.
Connecting to the KNIME Business Hub Admin Console
After you have successfully provisioned the KNIME Business Hub instance, you will need to connect to the Admin Console to configure the remaining setup of the KNIME Business Hub software.
To access and login to the Business Hub admin console, you will need the following:
-
The public IP address of the instance: this will be used as the URL to connect to the Hub Console from your browser
-
The Azure VMID: this is used as the admin password into the Admin Console. This password can be changed later.
You can find both of these items on the Azure VM instance summary page for said instance.
-
You will find the public IP address in the networking section
-
To find the Azure Instance VMID, you will need to click the JSON View button on the top right. Upon opening, search for the field vmid
Once you’ve obtained the IP address and the instance ID from the Azure console, open a new browser tab using the URL: <public-ip-address>:8800.
