Troubleshooting DNS on Kubernetes with NSX-T
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 »
Integrating Kubernetes with NSX-T 3.0
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 »
Kubernetes Application Deployment with Codestream
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 »
