To explain, we end up learning about Kubernetes API Groups, API Versions, and Resource Types.
This article was written using Kubernetes 1.20.X.
$ kubectl version…
A continuation of a walk-through of using Flux to deliver applications in a multi-cluster multi-tenant Kubernetes environment.
This article is a continuation of the article Flux Multi-Cluster Multi-Tenant by Example.
Here we refactor the Terraform configuration to support bootstrapping multiple clusters but sticking with the single-tenant case. …
A walk-through of using Flux to deliver applications in a multi-cluster multi-tenant Kubernetes environment.
Flux — the GitOps family of projects
Flux is a set of continuous and progressive delivery solutions for Kubernetes, and they are open and extensible.

Before we dig into Flux, it is…
A representative example of an event-driven application on Google Cloud Platform.
The example is an application that automates the creation / deletions of A records in a Google Cloud DNS internal Zone based on Google Compute Engine Instance insert, start, stop, and delete events.
The following diagram illustrates the Google…
An example of using Kubernetes snapshots.
The examples for this article are available for download. Also, while these examples are specific to Google Kubernetes Engine (GKE), the same concepts apply to other cloud providers, e.g., AWS and Elastic Kubernetes Engine (EKS).
Say we have a Kubernetes workload that requires a…
While it is well documented how CPU resource request impact the scheduling of Pods to Nodes, it is less clear of the impact once Pods (and their Containers) are running on a Node.
When thinking about resource requests, one focuses on its impact on scheduling Pods to Nodes.
When using multiple Projects, which Project an API call is attributed to is more complicated than one might think.
When using Google Cloud Platform (GCP), one often thinks about resources, e.g, storage buckets, instances, etc.; less apparent are the API calls made to access them. …
This is an unusual article as it is principally only exists to deliver and explain a Terraform configuration that can be used as part of a broader investigation of running workloads in a multi-cloud infrastructure; specifically Google Cloud Platform (GCP) and Amazon Web Services (AWS).
The specific requirements of this…
Operating GKE at scale is a bit harder than you may think.
First let us consider what Google Kubernetes Engine (GKE) is:
Secured and fully managed Kubernetes service with revolutionary autopilot mode of operation.
With this in mind, it sounds like an oxymoron for us to…
We wrap up this series by exploring one of Traffic Director’s advanced traffic management features.
This article is part of the series that starts with Traffic Director by Example: Part 1.
