This is the conclusion of a series on creating a Kubernetes cluster. In the previous post, we deployed an application to the Kubernetes (k8s) cluster and saw everything working end-to-end. I hope you enjoyed your journey with me and learned a lot along the

This is part of a series on creating a Kubernetes cluster. In the previous post, we dove deeper into Kubernetes networking and created an Ingress Controller to make our Services accessible. In this post, we'll be deploying an application to the Kubernetes (k8s) cluster.

This is part of a series on creating a Kubernetes cluster. In the previous post, we learned some Kubernetes networking concepts and added a Load Balancer to the cluster. In this post, we'll dive deeper into networking by creating an Ingress Controller. Before we

This is part of a series on creating a Kubernetes cluster. In the previous post, we provisioned the persistent storage for our applications. In this post, we'll start to build out the networking stack for our cluster. Before we get deep into the various

This is part of a series on creating a Kubernetes cluster. In the previous post, we installed Helm to make deployments easier. In this post, we'll start configuring our new Kubernetes (k8s) cluster by setting up persistent storage. In any containerized system, there is

This is part of a series on creating a Kubernetes cluster. In the previous post, we finalized the cluster by joining the worker nodes. In this post, we'll add one additional tool to our master node to help with Kubernetes (k8s) deployments. Helm is

This is part of a series on creating a Kubernetes cluster. In the previous post, we created the Kubernetes cluster and master node. In this post, we'll be joining the worker nodes to the Kubernetes (k8s) cluster. Worker nodes are intended to be configured

This is part of a series on creating a Kubernetes cluster. In the previous post, we installed Kubernetes on the servers. In this post, we'll be creating the Kubernetes (k8s) cluster and configuring the master node. To get started, we first need to create

This is part of a series on creating a Kubernetes cluster. In the previous post, we installed Debian 10 onto four virtual machines that will be used in the cluster. In this post, we will be installing Kubernetes (k8s) on them. Now that the

This is part of a series on creating a Kubernetes cluster. In this post, we'll be creating the virtual machines and preparing them to install Kubernetes (k8s). For my cluster, we'll be using four Debian 10 "buster" servers. These will be hosted on a

The release of .NET Core 3 raises the question of whether there are any impacts to the future direction of legacy .NET Framework applications that may be interested in moving to .NET Core in the future. The short answer is not really, but Core

The serializer from JSON.Net is really good, and the default output from JsonConvert.SerializeObject will work for most situations, but sometimes you want fine control over the structure of your JSON. Fortunately, JSON.Net also includes an API for building out custom JSON.

I am working on a project in which I want to export some tabular data in Markdown. I started writing methods to do this with each set of data, but that got to be tedious. I thought instead it would be easier to get

If you have any .Net Core Preview 2 applications that use project.json, you will encounter errors if you try to update to .Net Core Preview 3. This is due to the fact that .Net Core is moving away from project.json and will

I previously wrote about the Context Pattern where I used an example of temporarily turning off an event. I was recently writing a console application and came up with another use of the Context Pattern that I thought I would share. Often in a

I was writing a small tool recently and wanted to give it to some people in the office to use, but I wanted it to be simple. I was going to put it out on a network share, but I didn't like how I

Have you ever wanted to give your users some predefined choices for a time span (minutes, hours, etc)? That’s a pretty natural thing to do using language, but not such a natural thing to do using the TimeSpan class in .Net. You could

I came across a pretty neat nuget package that may very well be my go-to validation logic from now on. The package is called FluentValidation and seems to be a very flexible and usable fluent approach to object validation. There’s not much else

It has always been a minor pain that fields in a database can be null while the same value type in .Net cannot be. If you wanted to read a nullable DateTime field in the database into your object’s DateTime property, the only

I have had a recurring problem on my PC for a while where after some period of time Visual Studio will fail to start and show a generic error message box. I have multiple versions of Visual Studio and all would fail to load,

Today I encountered a scenario which I could describe with words much better than I could describe with code. I was reading results from a REST API, reading a few thousand records over multiple requests. I was saving these records to a database and

Sometimes you run across situations where there is just no good solution. No matter which option you choose, there are downsides. I found one such situation today when trying to design an interface. The code below are simple examples I wrote for the purposes

I recently found myself needing to periodically check the status of another operation, waiting for it to finish. In pseudocode, the basic operation is similar to this: while (!complete) { //check the status if ([completed]) complete = true; else //sleep 500ms } I did not want to

In my post on Debugging Different SOS Versions With WinDBG, I wrote how you often will need a different version of mscordacwks.dll, but I skipped over the part about how to obtain the version you need. Of course the natural answer is to
