Set Up Your VMware Virtual Machine for an On-premises Server Cluster
First configure the VM on the master node, and then configure the VM on each worker node.
Follow these steps to set up and configure your VM cluster for an on-premises deployment:
Verify that your master node meets the VM requirements.
Resource Minimum Requirements Processor Sixteen (16) virtual CPUs Memory 64 GB RAM Local disk storage 500 GB SSD with minimum disk IOPS of 1000 for a standard 4kb block size
(Note: This must be an SSD; use of other storage options can lead to system instability and are not supported.)
Network interface speed 1 Gb NIC Hypervisor VMware ESXi™ 6.5 or later (OVA image) for servers running Cumulus Linux, CentOS, Ubuntu, and RedHat operating systems
Confirm that the required ports are open for communications.You must open the following ports on your NetQ on-premises servers:
Additionally, for internal cluster communication, you must open these ports:
Port or Protocol Number Protocol Component Access 4 IP Protocol Calico networking (IP-in-IP Protocol) 22 TCP SSH 80 TCP Nginx 179 TCP Calico networking (BGP) 443 TCP NetQ UI 2379 TCP etcd datastore 4789 UDP Calico networking (VxLAN) 5000 TCP Docker registry 6443 TCP kube-apiserver 31980 TCP NetQ Agent communication 31982 TCP NetQ Agent SSL communication 32708 TCP API Gateway Port Protocol Component Access 8080 TCP Admin API 5000 TCP Docker registry 6443 TCP Kubernetes API server 10250 TCP kubelet health probe 2379 TCP etcd 2380 TCP etcd 7072 TCP Kafka JMX monitoring 9092 TCP Kafka client 7071 TCP Cassandra JMX monitoring 7000 TCP Cassandra cluster communication 9042 TCP Cassandra client 7073 TCP Zookeeper JMX monitoring 2888 TCP Zookeeper cluster communication 3888 TCP Zookeeper cluster communication 2181 TCP Zookeeper client
Port 32666 is no longer used for the NetQ UI.
Download the NetQ Platform image.
- On the NVIDIA Application Hub, log in to your account.
- Select NVIDIA Licensing Portal.
- Select Software Downloads from the menu.
- Click Product Family and select NetQ.
- Locate the NetQ SW 4.5 VMWare image and select Download.
- If prompted, agree to the license agreement and proceed with the download.
- On the NVIDIA Application Hub, log in to your account.
Setup and configure your VM.
Open your hypervisor and set up your VM. You can use this example for reference or use your own hypervisor instructions.
VMware Example ConfigurationThis example shows the VM setup process using an OVA file with VMware ESXi.
Enter the address of the hardware in your browser.
Log in to VMware using credentials with root access.
Click Storage in the Navigator to verify you have an SSD installed.
Click Create/Register VM at the top of the right pane.
Select Deploy a virtual machine from an OVF or OVA file, and click Next.
Provide a name for the VM, for example NetQ.
Tip: Make note of the name used during install as this is needed in a later step.
Drag and drop the NetQ Platform image file you downloaded in Step 2 above.
Select the storage type and data store for the image to use, then click Next. In this example, only one is available.
Accept the default deployment options or modify them according to your network needs. Click Next when you are finished.
Review the configuration summary. Click Back to change any of the settings, or click Finish to continue with the creation of the VM.
The progress of the request is shown in the Recent Tasks window at the bottom of the application. This may take some time, so continue with your other work until the upload finishes.
Once completed, view the full details of the VM and hardware.
Log in to the VM and change the password.
Use the default credentials to log in the first time:
- Username: cumulus
- Password: cumulus

Verify the master node is ready for installation. Fix any errors indicated before installing the NetQ software.
cumulus@hostname:~$ sudo opta-check
Change the hostname for the VM from the default value.
The default hostname for the NetQ Virtual Machines is ubuntu. Change the hostname to fit your naming conventions while meeting Internet and Kubernetes naming standards.
Kubernetes requires that hostnames are composed of a sequence of labels concatenated with dots. For example, “en.wikipedia.org” is a hostname. Each label must be from 1 to 63 characters long. The entire hostname, including the delimiting dots, has a maximum of 253 ASCII characters.
The Internet standards (RFCs) for protocols specify that labels may contain only the ASCII letters a through z (in lower case), the digits 0 through 9, and the hyphen-minus character ('-').
Use the following command:
cumulus@hostname:~$ sudo hostnamectl set-hostname NEW_HOSTNAME
Add the same NEW_HOSTNAME value to /etc/hosts on your VM for the localhost entry. Example:
127.0.0.1 localhost NEW_HOSTNAME
Verify that your first worker node meets the VM requirements, as described in Step 1.
Confirm that the needed ports are open for communications, as described in Step 2.
Open your hypervisor and set up the VM in the same manner as for the master node.
Make a note of the private IP address you assign to the worker node. You need it for later installation steps.
Verify the worker node is ready for installation. Fix any errors indicated before installing the NetQ software.
cumulus@hostname:~$ sudo opta-check-cloud
Repeat Steps 8 through 11 for each additional worker node you want in your cluster.
The final step is to install and activate the NetQ software using the CLI:
Run the following command on your master node to initialize the cluster. Copy the output of the command to use on your worker nodes:
cumulus@<hostname>:~$ netq install cluster master-init Please run the following command on all worker nodes: netq install cluster worker-init c3NoLXJzYSBBQUFBQjNOemFDMXljMkVBQUFBREFRQUJBQUFCQVFDM2NjTTZPdVVUWWJ5c2Q3NlJ4SHdseHBsOHQ4N2VMRWVGR05LSWFWVnVNcy94OEE4RFNMQVhKOHVKRjVLUXBnVjdKM2lnMGJpL2hDMVhmSVVjU3l3ZmhvVDVZM3dQN1oySVZVT29ZTi8vR1lOek5nVlNocWZQMDNDRW0xNnNmSzVvUWRQTzQzRFhxQ3NjbndIT3dwZmhRYy9MWTU1a
netq install cluster worker-init <ssh-key> on each of your worker nodes.
Run the following commands on your master node, using the IP addresses of your worker nodes:
cumulus@<hostname>:~$ netq install cluster full interface eth0 bundle /mnt/installables/NetQ-4.5.0.tgz workers <worker-1-ip> <worker-2-ip>
You can specify the IP address instead of the interface name here: use
ip-addr <IP address> in place of
interface <ifname> above.
If you have changed the IP address or hostname of the NetQ on-premises VM after this step, you need to re-register this address with NetQ as follows:
Reset the VM, indicating whether you want to purge any NetQ DB data or keep it.
cumulus@hostname:~$ netq bootstrap reset [purge-db|keep-db]
Re-run the install CLI on the appliance. This example uses interface eno1. Replace this with your updated IP address, hostname or interface using the interface or ip-addr option.
cumulus@hostname:~$ netq install standalone full interface eno1 bundle /mnt/installables/NetQ-4.5.0.tgz
If this step fails for any reason, you can run
netq bootstrap reset and then try again.
Verify Installation Status
To view the status of the installation, use the
netq show status [verbose] command. The following example shows a successful on-premises installation:
