Set Up Your VMware Virtual Machine for a Remote 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 remote deployment:

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

    ResourceMinimum Requirements
    ProcessorFour (4) virtual CPUs
    Memory8 GB RAM
    Local disk storage64 GB
    Network interface speed1 Gb NIC
    HypervisorVMware 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 NumberProtocolComponent Access
    4IP ProtocolCalico networking (IP-in-IP Protocol)
    22TCPSSH
    80TCPNginx
    179TCPCalico networking (BGP)
    443TCPNetQ UI
    2379TCPetcd datastore
    4789UDPCalico networking (VxLAN)
    5000TCPDocker registry
    6443TCPkube-apiserver
    31980TCPNetQ Agent communication
    31982TCPNetQ Agent SSL communication
    32708TCPAPI Gateway
    Additionally, for internal cluster communication, you must open these ports:
    PortProtocolComponent Access
    8080TCPAdmin API
    5000TCPDocker registry
    6443TCPKubernetes API server
    10250TCPkubelet health probe
    2379TCPetcd
    2380TCPetcd
    7072TCPKafka JMX monitoring
    9092TCPKafka client
    7071TCPCassandra JMX monitoring
    7000TCPCassandra cluster communication
    9042TCPCassandra client
    7073TCPZookeeper JMX monitoring
    2888TCPZookeeper cluster communication
    3888TCPZookeeper cluster communication
    2181TCPZookeeper client
    36443TCPKubernetes control plane

    Port 32666 is no longer used for the NetQ UI.

  3. Download the NetQ Platform image.

    1. On the My Mellanox support page, log in to your account. If needed create a new account and then log in.

      Your username is based on your Email address. For example, user1@domain.com.mlnx.
    2. Open the Downloads menu.
    3. Click Software.
    4. Open the Cumulus Software option.
    5. Click All downloads next to Cumulus NetQ.
    6. Select 4.0.0 from the NetQ Version dropdown.
    7. Select VMware (cloud) from the Hypervisor dropdown.
    8. Click Show Download.
    9. Verify this is the correct image, then click Download.

    The Documentation option lets you download a copy of the user manual. Ignore the Firmware and More files options as these do not apply to NetQ.

  4. 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 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 2 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. Log in to the VM and change the password.

    Use the default credentials to log in the first time:

    • Username: cumulus
    • Password: cumulus
    $ ssh cumulus@<ipaddr>
    Warning: Permanently added '<ipaddr>' (ECDSA) to the list of known hosts.
    Ubuntu 20.04 LTS
    cumulus@<ipaddr>'s password:
    You are required to change your password immediately (root enforced)

    cumulus@ubuntu:~$
    
  6. Verify the master node is ready for installation. Fix any errors indicated before installing the NetQ software.

    cumulus@hostname:~$ sudo opta-check-cloud
  7. 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
  8. 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-4.0.0.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-4.0.0.tgz
  9. Consider the following for container environments, and make adjustments as needed.

    Flannel Virtual Networks

    If you are using Flannel with a container environment on your network, you may need to change its default IP address ranges if they conflict with other addresses on your network. This can only be done one time during the first installation.

    The address range is 10.244.0.0/16. NetQ overrides the original Flannel default, which is 10.1.0.0/16.

    To change the default address range, use the CLI with the pod-ip-range option. For example:

    cumulus@hostname:~$ netq bootstrap master interface eth0 tarball /mnt/installables/netq-bootstrap-4.0.0.tgz pod-ip-range 10.255.0.0/16
    Docker Default Bridge Interface

    The default Docker bridge interface is disabled in NetQ. If you need to reenable the interface, contact support.

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

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

  12. 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.

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

    cumulus@hostname:~$ sudo opta-check-cloud
  14. Run the Bootstrap CLI on the worker node.

    cumulus@:~$ netq bootstrap worker tarball /mnt/installables/netq-bootstrap-4.0.0.tgz master-ip <master-ip>

    Provide a password using the password option if required. 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.

  15. Repeat Steps 10 through 14 for each additional worker node you want in your cluster.

The final step is to install and activate the 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:
