vSphere with Tanzu automatically deploys an NSX-T based load balancer for its supervisor cluster control plane. The load balancer size is defined as MEDIUM and requires an EDGE node of large size which is defined with 8 vCPU and 32GB RAM. While the creation of a supervisor cluster does also work with a medium sized… Read More »
Introduction In my previous post, we implemented NSX-T with Openshift 4 based without NCP’s support for Openshift operators (see https://www.vrealize.it/2020/07/15/nsx-t-ncp-integration-with-openshift-4-3-the-hard-way/). In the meantime, NCP 3.0.2 was released, which is implemented using an Openshift operator. The operator is also published on the Redhat Openshift Operator Hub (https://catalog.redhat.com/software/operators/detail/5ef0f362701a9cb8c147cf4b). That makes the installation way more simple, as you… Read More »
In this Blog I will explain how you can easily integrate NSX-T in the NSX Advanced Load Balancer (Formerly Avi Networks) and profit from the integrated solution.
Introduction Today, we’ll take a look at how to implement NSX-T’s container integration with Redhat Openshift 4.3.Before we begin, let me quickly explain why this blog post is called “The Hard Way”. Today with NSX-T 3.0 and NCP 3.0.1, support for Redhat Openshift can be provided by configuring the corresponding network config files during Openshift’s… Read More »
After integrating NSX-T with K8S I sometimes get issues with coredns not working. Common root cause: K8S internal DNS infrastructure needs non-NAT’ed network access from container PODs to K8S Nodes and vice versa. As NSX-T NCP default behaviour is to NAT your K8S Namespaces this can – depending on you overall architecture – cause connection… Read More »
This post shows how to integrate Kubernetes (1.18) running in vSphere 6.7 hosted Ubuntu 18.04 VMs with VMware NSX-T 3.0 This example uses the NSX NCP “shared Tier 1” topology meaning that all namespaces of the k8s cluster use the same T1 Gateway. Stateful services like Load-Balancing and NAT are applied to this T1 gateway.… Read More »
This post demonstrates how to integrate a bare-metal server on OS-Level into NSX-T overlay networking and security. As there was no bare-metal system in my demo environment available I created a CentOS 7.5 VM on a non-NSX enabled ESXi Server. Topology shown below After successful installation it should look like this Pre-Requisites: Have NSX-T up… Read More »
