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”

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 startContinue reading “NSX-T 3.0 and OpenShift 4.4 Integration”

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”
