Before deployment, consider the following requirements:
  • Customer-provided bare-metal systems running Linux and Docker version 19.03.5 and above.
  • The minimum supported Docker version is 19.03.5.
  • Non-standard paths to the Docker daemon socket, such as during Docker installation with Snap, are not supported.
  • Kubernetes is not supported.
  • VMs deployed on VMware ESXi servers:
    • For regular OVA deployment, supported VMware ESXi server versions are 6.0, 6.7, and 7.0.
    • For high capacity OVA, deployment, supported VMware ESXi serves version 6.5 and above.

For information on how to download OVA packages, see Downloading BloxOne Apps.

  • VM infrastructures such as Hyper-V or KVM, running Linux and Docker version 19.03.5 or above. For information about the supported Linux VMs for Hyper-V, refer to this article.


Dind (Docker-in-Docker) configuration is not supported for on-prem host deployments.

Infoblox has validated the following platforms:

  • Red Hat Enterprise Linux 7.8
  • CentOS 7.8
  • Ubuntu: For new deployments, Infoblox recommends Ubuntu 18.04 while we continue to support Ubuntu16.04 for existing deployments.

For bare-metal configuration, ensure that the following requirements are in place:

  • Avoid CIDR overlapping with the default CIDR
  • No K3s binary should be placed in this directory: /usr/local/bin/
  • SELinux policy is properly set up


For k3s to be successfully installed on a Red Hat and CentOS based bare-metal on-prem host, use the following command to install the required package:

yum install -y container-selinux selinux-policy-base
rpm -i

After you install the required package, complete the following:

  1. Disable the firewall service.
  2. Enable the iptables service (if it exists).
  3. Reboot the system.


It is highly recommended that you adhere to the minimum hardware and platform requirements for on-prem hosts. DHCP version 3.1 or higher is required for DHCP clustering (Advanced Active-Passive). If you do not follow the minimum hardware and platform requirements for on-prem hosts, DHCP clustering will not be supported. For more information about DHCP Clustering, see Creating HA Groups.
