Modernizing integration system software stack

by Giang Pham 15 September, 2020

Introduction

The world of computing has rapidly evolved over the years. We are now equipped with plenty of tools and software which is great for making our life a lot easier and more modern than ever before. Containers and container-orchestration systems have opened a brand new way of doing things, from allowing us to achieve automation of development and deployment to performing massive scale at fingertips and so much more. This post is an introduction to modernizing integration system software stack using a number of different tools and why they have been selected.

Dockerizing a full .NET App for Windows Containers running in Kubernetes

by Giang Pham 31 July, 2020

Windows containers have been out there for a few years but I feel like it is now time to have our full .NET apps running in Kubernetes for production. The reason why I say this is because Kubernetes starts supporting Windows Containers running in AKS from version v1.14 and the supported Windows node’s OS must be Windows Server 1809/Windows Server 2019 or later. Of course, you don’t have to run a full .NET app in a Windows node but the question is why it even exists when you don’t have a plan to run them. That discussion is not the purpose of this post though.

CI/CD Infrastructure As Code Kubernetes Microsoft Azure

Deploying a multiple node pools Kubernetes cluster to Azure (AKS) using Terraform

by Giang Pham 24 June, 2020

You are probably excited about containers just like I did when I first heard about them a few years ago. In the past, we would deploy our multi-container apps using Docker compose to a docker swarm and have it managed our containerized apps and this worked but also added a lot of complexity. I started looking for new ways to manage my containers and I came across Kubernetes. I just went … wow! I had a few posts previously talking about Kubernetes but they were mostly general discussions. This post is going to be a long one, from the planning step to the final way out. I will address why I choose such an infrastructure as we are moving through.

.Net Core Backend Helm Kubernetes

Deploying a .Net Core Worker Service to a Minikube VM

by Giang Pham 7 April, 2020

Minikube is a way to run Kubernetes locally. It is a tool that runs a single-node Kubernetes cluster inside a Virtual Machine (VM) on your computer, either Linux, Windows or Mac. It is a quick way to try out Kubernetes and is also useful for testing and development scenarios. Before we dive into the deployment part, let’s highlight some of the alternatives that we have. There is a number different ways we can deploy our containerized apps to a Kubernetes cluster:

Containerization Kubernetes

A Brief Introduction to Kubernetes in Azure

by Giang Pham 6 April, 2020

I’ve been searching for a better solution to monitor our on-prem applications. I know these apps do their job just fine but I don’t like the way they stop working without my acknowledgement. One day a message came from the sales team asking “hey I won a quote but I didn’t see it in Navision”. I then had a look in the server and realized that the service somehow stopped working. So I restarted the service and it went back to normal. This is just a simple example of how we manage our apps manually. I’d like to have them automated. It’s time to enter Kubernetes.

Windows Authentication for Linux containers running inside Azure Kubernetes Service (AKS)

by Giang Pham 30 March, 2020

Carry on with what we have been doing in the previous post regarding deploying containerized apps to AKS. This post addresses some of the issues and how we are going to solve it. My main goal is to allow the app to have access to the on-prem resources using Windows Authentication for Linux containers, just like we would normally do with our apps running on an intranet network. I briefly mentioned our approach to achieve this using Azure VNet. In case you haven’t seen that post, here is the link.

Containerization Infrastructure As Code Kubernetes

Deploying to Azure Kubernetes Service (AKS) on an existing Azure VNet using Ansible

by Giang Pham 28 March, 2020

Deploying containerized apps to a Azure Kubernetes Service (AKS) cluster using the default settings in Azure isn’t that much tough as the tools handle most of the hard work for us. I recently discovered a scenario where I needed to connect my AKS cluster back to the on-prem resources. So I went ahead and created a AKS cluster via the Azure portal. In the creation step, I chose Azure VNet and this automatically set my cluster to use Azure Networking Interface (CNI).
