Run Node.js application in Docker & deploy it to Microsoft Azure

Utilising cloud services make it easy to deploy Node.js applications online, without the need to setup an own virtual private server (VPS) and install and configure the needed operating system and/or runtimes in it. It’s also an important tool for the realisation of web solutions based on micro services.

In this article, I’ll show how to run a minimal Node.js application inside Docker and deploy it to Microsoft Azure using the Azure Container Registry and Azure App Services.
