I encountered an issue while playing with Container Service Extension 3.1.1 in my lab where I was unable to construct TKGm clusters. During troubleshooting, I discovered that the Rights Bundle “cse:nativeCluster Entitlement” was missing certain critical rights that are newly added with CSE 3.1.1.

On attempting to delete the failed clusters, the clusters stuck in the state “DELETE:IN_PROGRESS”.

On attempting to delete the failed cluster via vcd-cli, the operation failed with the error “RDE_ENTITY_NOT_RESOLVED“

Welcome to the 4th part of the NSX Advanced Load Balancer Integration with VMware Cloud Director series. The first post in this series covered Service Engine design topologies, while the second covered the processes for enabling “Load Balancing as a Service” in VCD. The deployment of the Dedicated Service Engine design was demonstrated in the third post.

This post will talk about the implementation of the Shared Service Engines design.

3: Implementing Dedicated Service Engine Groups Design

In Shared Service Engine Group design, tenant’s Edge Gateways can leverage a common Service Engine Group for the load balancer and virtual services placement. Since VCD tenants can have overlapping org networks implemented in their respective org’s, data traffic segregation is achieved by implementing VRF’s in NSX ALB.  … Read More

I discussed the supported design for NSX ALB integration with the VMware Cloud Director in the first post of this series. Part 2 of this series described how to enable “Load Balancing as a Service” in VCD. 

If you missed any of the previous posts in this series, I recommend that you read them using the links provided below.

2: NSX ALB Integration in VCD

This blog post is focused on implementing the Dedicated Service Engine Groups design.

The below diagram shows the high-level overview of Dedicated SEG in VCD.

In this design, the management network of Service Engine (eth0) is attached to the tier-1 gateway dedicated for NSX ALB management and provisioned by the service provider. When a Virtual Service is created by the tenant, a logical segment corresponding to the VIP network is automatically created and gets attached to the tenant’s tier-1 gateway.… Read More

NSX ALB Integration with VCD-Part 2: NSX ALB & Infra Configuration

Posted on by

In the first post of this series, I discussed the design patterns that are supported for NSX ALB integration with VCD.

In this post, I will share the steps of the NSX ALB & Infra configuration, before implementing the supported designs. 

Step 1: Configure NSX-T Constructs

1a: Deploy a couple of new Edge nodes to place the Tier-0 gateway that you will be creating for the NSX ALB consumption. 

Associate the newly deployed edge nodes with the existing Edge Cluster.

1b: Create a Tier-0 and configure BGP. Also, ensure that Tier-1 connected segments are allowed to be redistributed via BGP.

1c: Create a Tier-1 gateway and associate it with the Tier-o gateway that you created in the previous step.

Ensure that the tier-1 gateway is configured to redistribute connected routes to the tier-0 gateway. 

1d: Create a DHCP-enabled logical segment for the Service Engine management and connect the segment to the tier-1 gateway which you created in the previous step.… Read More

Overview

NSX Advanced Load Balancer provides multi-cloud load balancing, web application firewall, application analytics, and container ingress services from the data center to the cloud. It is an Intent-based software load balancer that provides scalable application delivery across any infrastructure. NSX ALB provides 100% software load balancing to ensure a fast, scalable and secure application experience. It delivers elasticity and intelligence across any environment.

With the release of VCD 10.2, NSX Advanced Load Balancer integration is available for use by the tenants. Service Provider configured NSX ALB and exposes load balancing functionality to the tenants so that tenants can deploy load balancers in a self-service fashion. 

The latest release of VCD (10.3.1) supports NSX ALB versions up to 21.1.2. Please check the VMware product interop matrix before planning your deployment.

In this blog post, I will be talking about the NSX ALB design patterns for VCD and the ALB integration steps with VCD.… Read More

Tanzu Kubernetes Grid multi-cloud Integration with VCD – Greenfield Installation

Posted on by

With the release of Container Service Extension 3.0.3, service providers can integrate Tanzu Kubernetes Grid multi-cloud (TKGm) with VCD to offer Kubernetes as a Service to their tenants. TKGm integration in addition to existing support for Native K8 and vSphere with Tanzu (TKGS) has truly transformed VCD into a developer-ready cloud. 

With Tanzu Basic (TKGm &TKGS) on VCD, tenants have a choice of deploying K8s in three different ways: 

  • TKGS:  K8 deployment on vSphere 7 which requires vSphere Pod Service 
  • TKGm: Multi-tenant K8 deployments that do not need vSphere Pod Service. 
  • Native K8: Community supported Kubernetes on VCD with CSE 

By offering multi-tenant managed Kubernetes services with Tanzu Basic and VCD, Cloud providers can attract developer workloads starting with test/dev environments to their cloud. Once developers have grown confidence in the K8 solution, application owners can leverage the VCD-powered clouds to quickly deploy test/dev K8s clusters on-premise and accelerate their cloud-native app development and transition to production environments.… Read More

Native Kubernetes in VCD using Container Service Extension 3.0

Posted on by

Introduction

VMware Container Service is an extension to Cloud Director which enables VCD cloud providers to offer Kubernetes-as-a-Service to their tenants. CSE integration with VCD has allowed CSPs to provide true developer-ready cloud offering to VCD tenants. Tenants can quickly deploy the Kubernetes cluster in just a few clicks directly from the VCD portal. 

Cloud Providers upload customized Kubernetes templates in public catalogs which tenants leverage to deploy K8 clusters in self-contained vApps. Once the K8 cluster is available, developers can use their native Kubernetes tooling to interact with the cluster.

To know more about the architecture and interaction of CSE components, please see my previous blog on this topic.

Container Service Extension 3.x went GA earlier this year and brought several new features/enhancements and one of them is supporting Tanzu Kubernetes Grid multi-cloud (TKGm) for K8 deployments and thus unlocking the full potential of consistent upstream Kubernetes in their VCD powered clouds.… Read More

Overview

Prior to v10.2, VMware Cloud Director supported K8 cluster deployment natively and integrated with ENT-PKS. With the release of v10.2, K8 integration is extended to vSphere with Tanzu. This integration enables Service Providers to create a self-service platform for Kubernetes Clusters that are backed by the vSphere 7.0 and NSX-T 3.0. By using Kubernetes with VMware Cloud Director, you can provide a multi-tenant Kubernetes service to your tenants.

In this article, I will walk through the steps of integrating vSphere with Tanzu with VCD. 

Pre-requisites for Tanzu Integration with VCD

Before using vSphere With Tanzu with VCD, you have to meet the following pre-requisites:

  • VMware Cloud Director appliance deployed & initial configuration completed. Please see VMware’s official documentation on how to install & configure VCD.
  • vCenter 7.0 (or later version) with an enabled vSphere with VMware Tanzu functionality added to VMware Cloud Director. This is done under Resources > Infrastructure Resources > vCenter Server Instances.

This blog post provides an overview of the HCX installation workflow for VMware Cloud Director based Clouds.

The below diagram taken from VMware official docs shows the high-level architecture of HCX architecture for VCD based clouds.

HCX Cloud System & Network Requirements

Before starting HCX Cloud installation, please ensure that you’ve met all the System and Network Port/Protocol requirements. These are documented Here

Firewall Requirements

  • The site’s WAN firewall will need to allow inbound HTTPS connections destined for the HCX Cloud. HCX Cloud will make outbound HTTPS requests.
  • The HCX Cloud site firewall also needs to allow inbound UDP-500 and UDP-4500 connections destined for the HCX appliances.
  • All other flows allow HCX to integrate with VMware SDDC components, typically these are not firewalled within the datacenter

The below diagram shows various ports that must be allowed in the firewall for a successful HCX cloud deployment in the destination environment.

VMware Cloud Director Pre-requisites

Make sure the following is already configured in VCD:

1: VCD Public Address is set and load balancer cert is imported (for multi-cell deployment)

2: RabbitMQ is installed and configured into VCD. … Read More
