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, isContinue reading “EKS Networking with Antrea”

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 extendsContinue reading “GKE Networking with Antrea”

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 securityContinue reading “OpenShift Networking with Antrea”

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. determiningContinue reading “Troubleshooting Kubernetes Connectivity with Antrea TraceFlow”

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 AntreaContinue reading “Deploying Antrea on Mac with Octant Plugin”

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 onContinue reading “Pimp Your Terminal for Kubernetes”

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 isContinue reading “Kubernetes Infrastructure”
