This Blog will Guide you through the complete Installation from NAPP without using Tanzu and NSX Advanced Load Balancer. If you have Tanzu and NSX Advanced Load Balancer installed, I highly recommend to use your existing Tools!
Starting with NSX-T 3.2 its now possible to act as central security control plane for Antrea enabled k8s clusters. This post shows how to set up and gives a short introduction how it works. Prerequisites: have NSX-T 3.2 up and running Prepare 3 Ubuntu 18.04 VMs (4 CPU, 4GB RAM, 25GB Storage), minimum install with… Read More »
Update: January 2021 update with current versions (Antrea v0.12.0 AKO 1.13 / Controller 20.1.3) This post shows how to integrate Antrea Container Networking with NSX Advanced Load Balancer (NSX ALB) using AVI Kubernetes Operator (AKO) This example shows integration of a single K8S cluster with NSX ALB. If you plan to integrate more than one… 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 »
Deployment of a Kubernetes application into production requires a well-defined process. It is not only about the actual deployment but also about having the right test procedure in place as well as updating existing applications with new versions. In contrast to legacy applications where frequency of updates is rather low, modern containerized applications can have… Read More »
