Deploy Application from a .YAML File to Azure AKS

Following my previous articles about Azure Kubernetes Cluster (AKS) today, I will show you how I deploy a web application to AKS using a .YAML file.

About AKS

Released a few weeks ago and currently, in public preview, AKS offer a managed Kubernetes cluster that can be scaled up and on demand without needing to configure Containers, host, storage networks etc.

Requirements

To get the Web App running in AKS you will a running AKS cluster with minimum one Node.

For setup instructions visit my article about Deploying AKS in Azure.

Get Started

In this post, I will be using the Kubernetes Web UI (Dashboard) which comes with AKS to deploy the application and below I will connect to my AKS dashboard.

Once connected to the Dashboard I will click on create

In the create from text Input screen, I will paste my .YAML file content (the file is a basic voting app released by Microsoft)
