GSLB for Kubernetes using NSX-ALB
In previous blogs I showed how to deploy NSX-ALB (Avi) for application delivery as a Load Balancer and Ingress Controller for multiple Kubernetes Distributions. When working with Kubernetes or OpenShift in a multicluster (possibly hybrid cloud) deployment, one of the considerations that comes up is how to direct traffic to the applications deployed across these…
OpenShift Integration with NSX-ALB
NSX-ALB could add a lot of values to OpenShift compared to the built-in OpenShift Router. The OpenShift Router is limited to OpenShift Routes and Ingress (HTTP/HTTPS Load Balancing) with very limited visibility. While NSX-ALB will add below main values, All above features are typically needed in a production OpenShift deployments, and NSX-ALB provides them all…
TKG Integration with NSX
NSX could add great values in Kubernetes environment by providing consisting Networking and Security across VMs and Containers. In this post I will show how to integrate TKG with NSX in a vSphere 8 environment to highlight the values of NSX with TKG. TKG uses Antrea as a CNI which can be integrated with NSX.…
EKS Networking with Antrea
In previous posts, I explored how to deploy and test Antrea on your laptop, Tanzu, OpenShift and GKE. The more I use Antrea, the more I come to appreciate it as a CNI Plugin that is high performance, feature rich and very easy to deploy and use. What makes me more exited about it, is…
GKE Networking with Antrea
In this post I will explore deploying Antrea on a GKE Cluster. Antrea is an OpenSource CNI Plugin for Kubernetes. It has some good performance and features advantages compared to other CNI Plugins in the market. Antrea leverage OVS as a DataPlane, which is widely adopted and high-performance programmable virtual switch.From features prospective, Antrea extends…
OpenShift Networking with Antrea
Antrea is an OpenSource CNI Plugin for Kubernetes. It has some good performance and features advantages compared to other CNI Plugins in the market.Antrea leverage OVS as a DataPlane, which is widely adopted and high-performance programmable virtual switch.From features prospective, Antrea extends native K8s NetworkPolicy to have more granular policy by adding hierarchy of security…
Tanzu Kubernetes Cluster Ingress with NSX-ALB
In this blog I will show how to use NSX-ALB (Avi) for Tanzu Kubernetes Clusters (TKC) as an Ingress and a Load Balancer in a vSphere with Tanzu environment on top of NSX-TI am running vSphere 7U1 with NSX-T 3.1. The main motivation for this exercise is to provide an Ingress Controller for TKCs. Today…
NSX-ALB Deployment and Integration with NSX-T
In this blog I will show the steps needed to integrate NSX Advanced Load Balancer (NSX-ALB) previously known as Avi with NSX-T Data Center. NSX-ALB is a multi-cloud Software Defined Load Balancer. It includes great feature such as analytics, GSLB, WAF, and Kubernetes Integration. In This blog i will show how deploy and integrate NSX-ALB…
Troubleshooting Kubernetes Connectivity with Antrea TraceFlow
In this blog I will explain how to troubleshoot pod-to-pod or pod-to-ip traffic with a new function in Antrea called Traceflow, and visualize it with Octant UI. Traceflow enables a CRD API for Antrea that supports generating tracing requests for traffic going through the Antrea-managed Pod network. This is useful for troubleshooting connectivity issues, e.g. determining…
NSX-T 3.0 and OpenShift 4.4 Integration
In this blog I will go through NSX-T 3.0 and OpenShift 4.4 integration using the new NSX-T Operator for OpenShift. The Blog is based on personal testing for the NSX-T Openshift Operator published here and it is not validated by both vendors. The test was done on vSphere 7 with VSAN storage. We can start…
Deploying Antrea on Mac with Octant Plugin
Antrea is a Kubernetes networking solution intended to be Kubernetes native. It operates at Layer3/4 to provide networking and security services for a Kubernetes cluster, leveraging Open vSwitch as the networking data plane. Open vSwitch is a widely adopted high-performance programmable virtual switch; Antrea leverages it to implement Pod networking and security features. For instance, Open vSwitch enables Antrea…
Pimp Your Terminal for Kubernetes
In this blog i will list some of the tools that could pimp your Mac terminal for Kubernetes iTerm2https://www.iterm2.com/features.htmlIt simply better terminal with better tabs and windows management than Mac default terminal. Oh My ZSHhttps://ohmyz.sh/it replaces bash! it makes plugin installations and aliases easier. Kube-PS1https://github.com/jonmosco/kube-ps1kube-ps1 will show the cluster and namespace you are in on…
Kubernetes Infrastructure
Kubernetes (K8s) is a portable, extensible, open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available. Source: https://kubernetes.io K8s take very good care of the applications that run on top it, but the infrastructure is…
