Containerization Technologies and Best Practices

Your firewall says Default: deny (incoming). Your database is answering the internet anyway. This part shows the port scan that proves it on a real server, explains the iptables chain order that causes it, and fixes it with a Compose override file — not by fighting the firewall.
Learn how to run Dewiride Analytics on your own Ubuntu Server — an open-source web analytics engine that tells you which of your visitors were actually people. This part covers the firewall, the repository, the two passwords you must set yourself, and the single command that brings four containers up and waits until every one of them is genuinely healthy.
Learn how to run WordPress on an Ubuntu Server using Docker — with the website and its database in two tidy containers instead of installed all over your system. This part covers the project folder, a .env file for your passwords, the compose.yaml file explained line by line, and finishing the famous five-minute WordPress installer in your browser.
Getting an app deployed is the easy half. This final part covers what you actually do with a running app: read its logs, understand how it scales, know what it costs — and take it all down again.
This is the part where it becomes real. Four tabs in the Azure portal and your container gets a public HTTPS address that anyone in the world can open.
This is the shortest part of the series and the one most likely to save you an afternoon. Pushing an image is three commands — but if you're on an Apple Silicon Mac, one missing flag produces a container that builds perfectly, pushes perfectly, and then refuses to start on Azure.
Your container image is stuck on your laptop, and Azure can't reach your laptop. In this part you'll create the two Azure resources that fix that: a resource group to hold everything, and a container registry to store the image.
Your app works on your machine because your machine happens to have .NET 10 installed. A container removes that "happens to" — it packages the app and the runtime into one box that behaves identically everywhere.
Most "deploy to the cloud" tutorials skip the part where you actually understand what you built. This series does the opposite: six short parts that take you from an empty folder to a real, public URL on Azure, explaining every command along the way.
Learn how to install Docker Engine on Ubuntu Server using Docker's official apt repository. This step-by-step guide covers setting up the Docker repository, installing the engine and CLI, running Docker without sudo, enabling it to start on boot, and verifying everything works with the hello-world container.
