How does Kubernetes Ingress work?

In this quick video, we answer the question of how Ingresses in Kubernetes work. Ingresses manage external access to services and pods within a cluster. We start with three pods in our cluster, with their IP addresses ending at .9, .17, and .22. These pods use an existing pod network with the CIDR of 10.32.x./16.…

Using Raw API calls to control Kubernetes

This quick video explains how you configure Kubernetes pods to control Kubernetes itself with raw API calls. Most users interact with Kubernetes using kubectl. kubectl itself is a sophisticated wrapper for “curl” and communicates with a Kubernetes cluster’s API server. Using the -v flag followed by a number tells kubectl to show the exact call…

Navigating network services and policy with Helm

Managing all of these resources and relating them to deployed apps can be challenging, especially when it comes to tracking changes and updates to the deployed application…

One-Way Pod Scaling with the Kubernetes HPA

Kubernetes has the ability to dynamically scale sets of pods based on resource usage. This is great for ensuring that applications always have the resources they need as loads vary. Autoscaling the number of pods in Kubernetes is most often accomplished using a Horizontal Pod Autoscaler (HPA). HPAs dynamically adjust the replica count of a…

Vitess: Sharded MySQL on Kubernetes

Though the relational data model inherently fights horizontal scaling attempts, it is the best understood and most used data model in the world. More than one company has planted its storage flag in the MySQL/MariaDB soil only to be confounded by success and the scalability challenges that come with it. Fortunately for users like YouTube…
