Set Up Your VMware Virtual Machine for a Cloud Server Cluster

First configure the VM on the master node, and then configure the VM on each worker node.

Follow these steps to setup and configure your VM on a cluster of servers in a cloud deployment:

1. Verify that your master node meets the VM requirements.

   Resource	Minimum Requirements
   Processor	Four (4) virtual CPUs
   Memory	8 GB RAM
   Local disk storage	64 GB
   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

2. Confirm that the needed ports are open for communications.

   You must open the following ports on your NetQ on-premises servers:

   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
   30001	TCP	DPU communication
   31980	TCP	NetQ Agent communication
   31982	TCP	NetQ Agent SSL communication
   32708	TCP	API Gateway

   Additionally, for internal cluster communication, you must open these ports:

   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
   36443	TCP	Kubernetes control plane

3. Download the NetQ Platform image.

   1. On the MyMellanox Downloads page, select NetQ from the Software -> Cumulus Software list.
   2. Click 2.4 from the Version list, and then select 2.4.1 from the submenu.
   3. Select VMware (Cloud) from the HyperVisor/Platform list.

      

   4. Scroll down to view the image, and click Download.

      

4. Setup and configure your VM.

   VMware Example Configuration

   This example shows the VM setup process using an OVA file with VMware ESXi.

   1. Enter the address of the hardware in your browser.

   2. Log in to VMware using credentials with root access.

      

   3. Click Storage in the Navigator to verify you have an SSD installed.

      

   4. Click Create/Register VM at the top of the right pane.

      

   5. Select Deploy a virtual machine from an OVF or OVA file, and click Next.

      

   6. 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.

   7. Drag and drop the NetQ Platform image file you downloaded in Step 1 above.

   

   8. Click Next.

   9. Select the storage type and data store for the image to use, then click Next. In this example, only one is available.

      

   10. Accept the default deployment options or modify them according to your network needs. Click Next when you are finished.

       

   11. 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.

   12. Once completed, view the full details of the VM and hardware.

       

5. Verify the master node is ready for installation. Fix any errors indicated before installing the NetQ software.

   cumulus@hostname:~$ sudo opta-check-cloud

6. Run the Bootstrap CLI. Be sure to replace the eth0 interface used in this example with the interface on the server used to listen for NetQ Agents.

   cumulus@:~$ netq bootstrap master interface eth0 tarball /mnt/installables/netq-bootstrap-2.4.1.tgz

   Allow about five to ten minutes for this to complete, and only then continue to the next step.

   If this step fails for any reason, you can run netq bootstrap reset and then try again.

   If you have changed the IP address or hostname of the NetQ Cloud VM after this step, you need to re-register this address with NetQ as follows:

   Reset the VM.

   cumulus@hostname:~$ netq bootstrap reset

   Re-run the Bootstrap CLI. This example uses interface eth0. Replace this with your updated IP address, hostname or interface using the interface or ip-addr option.

   cumulus@:~$ netq bootstrap master interface eth0 tarball /mnt/installables/netq-bootstrap-2.4.1.tgz

7. Verify that your first worker node meets the VM requirements, as described in Step 1.

8. Confirm that the needed ports are open for communications, as described in Step 2.

9. Open your hypervisor and setup 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. It is needed for later installation steps.

10. Verify the worker node is ready for installation. Fix any errors indicated before installing the NetQ software.

    cumulus@hostname:~$ sudo opta-check-cloud

11. Run the Bootstrap CLI on the worker node.

    cumulus@:~$ netq bootstrap worker tarball /mnt/installables/netq-bootstrap-2.4.1.tgz master-ip <master-ip> [password <text-password>]

    Allow about five to ten minutes for this to complete, and only then continue to the next step.

    If this step fails for any reason, you can run netq bootstrap reset on the new worker node and then try again.

12. Repeat Steps 7 through 11 for each additional worker node you want in your cluster.

The final step is to install and activate the Cumulus NetQ software. You can do this using the Admin UI or the CLI.

Click the installation and activation method you want to use to complete installation:

• Use the Admin UI (recommended)
• Use the CLI
