Installing and Configuring containerd as a Kubernetes Container Runtime

This post shows you how to install containerd as the container runtime in a Kubernetes cluster. I will also cover setting the cgroup driver for containerd to systemd, which is the preferred cgroup driver for Kubernetes. In Kubernetes version 1.20 Docker was deprecated as a container runtime in a Kubernetes cluster and support was removed in 1.22. Kubernetes 1.26 now requires that you use a runtime that conforms with the Container Runtime Interface (CRI).

Writing a Hello World Go Container Web Application

In this blog post, I will show you how to build a hello world container-based web application in the go programming language. The reason I want to do this is because I need a very small container image to do some testing in Kubernetes. I’ll also highlight some of the pitfalls I ran into to hopefully have you some time in your learnings. Let’s build and test it locally first Before you build a container-based application, you need an application.

Setting Permissions on Files Inside a Container for SQL Server

This post will walk you through setting file permissions on database files copied into a container. The SQL Server process sqlservr running in containers runs as the non-privileged user mssql. The appropriate permissions on files are needed, so the SQL Server process has the proper access to any database files, log files, and backup files. Start up a container First up, let’s start up a container. Here’s we’re starting up SQL Server 2019 CU11 and attaching a Docker data volume for our persistent data.
