Installation

BNG CUPS Controller Requirements

Juniper BNG CUPS 24.4R1 and 24.4R2 installation requires the minimum system requirements listed in this section.

The BNG CUPS Controller can be installed on a single Kubernetes cluster or on a multiple geography, multiple cluster setup. The installation requirements and installation process for these two types of setups are different.

For information on how to install Juniper BNG CUPS, see Juniper BNG CUPS Installation Guide.

BNG CUPS Controller installs on a Kubernetes cluster comprised of physical or virtual machines (VMs).

For the Kubernetes cluster requirements for your setup, see the following:

Table 1: Single Kubernetes Cluster Setup Requirements
Category Details

Cluster

A single cluster with 3 hybrid nodes.
Kubernetes node

The Kubernetes nodes require the following:

  • For the operating system, you can use either of the following:

    • Ubuntu 22.04 LTS (for a BBE Cloudsetup cluster)

    • Red Hat Enterprise Linux CoreOS (RHCOS) 4.16 or later (for an OpenShift Container Platform cluster)

  • CPU: 16 cores

  • Memory: 64 GB

  • Storage: 512 GB storage partitioned as 128 GB root (/), 128 GB /var/lib/docker, and 256 GB /mnt/longhorn(application data

  • Kubernetes role: Control plane etcd function and worker node

This specification establishes a cluster that can run BNG CUPS Controller as well as its companion applications such as BBE Event Collection and Visualization and Address Pool Manager (APM) simultaneously.

Jump host

 The jump host requires the following:

  • Operating system: Ubuntu version 22.04 LTS

  • CPU: 2 core

  • Memory: 8 gibibytes (GiB)

  • Storage: 128 gibibytes (GiB)

  • Installed software:

    • Python 3.10-venv

    • Helm utility

    • Docker utility

    • OpenShift CLI. Required if you are using a Red Hat OpenShift Container Platform cluster.

Cluster software

The cluster requires the following software:

  • RKE version 1.3.15 (Kubernetes 1.24.4)—Kubernetes distribution

  • MetalLB version 0.13.7—Network load balancer

  • Keepalived version 2.2.8—Kubelet HA VIP Controller

  • Longhorn version 1.2.6—CSI

  • Flannel version 0.15.1—CNI

  • Registry version 2.8.1—Container registry

  • OpenShift version 4.16 or later—Kubernetes Distribution for RHOCP. Uses compatible versions of Longhorn (CSI), and MetalLB, OVN (CNI), and OpenShift Image Registry

Jump host software

The jump host requires the following software:

  • Kubectl version 1.28.6+rke2r1—Kubernetes client

  • Helm version 3.12.3—Kubernetes package manager

  • Docker-ce version 20.10.21—Docker engine

  • Docker-ce-cli version 20.10.21—Docker engine CLI

  • OpenShift version 4.16 or later—Kubernetes distribution for RHOCP clusters.

Storage

A storage class named jnpr-bbe-storage.

Network load balancer address

Two for TCP and UDP load balancing services.

Registry storage

Each BNG CUPS Controller release requires 2 gibibytes (GiB) of container images.

Table 2: Multiple Geography Kubernetes Cluster Setup Requirements
Category Details

Cluster

The multiple cluster consists of three clusters with each cluster consisting of 3 hybrid nodes.

The three clusters must consist of one management cluster and two workload clusters.

Note:

Make sure that the cluster and service CIDRs for each workload cluster do not overlap. The cluster internal networks of each workload cluster are connected by a Submariner IP tunnel. The internal CIDRS must be distinct.

Management cluster, Kubernetes node

The management cluster Kubernetes node requires the following:

  • For the operating system, you can use either of the following:

    • Ubuntu 22.04 LTS (for a BBE Cloudsetup cluster)

    • Red Hat Enterprise Linux CoreOS (RHCOS) 4.16 or later (for an OpenShift Container Platform cluster)

  • CPU: 8

  • Memory: 24 GB

  • Storage: 256 GB of storage partitioned according to the following:

    • On a Rancher Kubernetes Engine 2 (RKE2) system—64 GB root (/), 96 GB /var/lib/rancher, and 96 GB /var/lib/longhorn (application data)

    • On a RHOCP system—64 GB root (/), 96 GB /var/lib/containers, and 96 GB /var/lib/longhorn

  • Kubernetes role: Control plane etcd function and worker node

This specification establishes a cluster that can run Karmada and ECAV simultaneously.
Workload cluster, Kubernetes node

The workload cluster Kubernetes node requires the following:

  • For the operating system, you can use either of the following:

    • Ubuntu 22.04 LTS (for a BBE Cloudsetup cluster)

    • Red Hat Enterprise Linux CoreOS (RHCOS) 4.16 or later (for an OpenShift Container Platform cluster)

  • CPU: 16 cores

  • Memory: 64 GB

  • Storage: 512 GB of storage, partitioned according to the following:

    • On a RKE2 system— 128 GB root (/), 128 GB /var/lib/rancher, 256 GB /var/lib/longhorn;

    • On a RHOCP system—128 GB root (/), 128 GB /var/lib/containers, and 256 GB /var/lib/longhorn

  • Kubernetes role: Control plane etcd function and worker node

This specification establishes a cluster that can run BNG CUPS Controller as well as its companion applications such as BBE Event Collection and Visualization and APM simultaneously.
