Containerization with Docker and Kubernetes: A Primer
Containerization has moved from an emerging trend to a baseline expectation in modern software delivery. If your team deploys applications to the cloud, understanding Docker and Kubernetes is no longer optional — it is a core competency. This primer covers the essential concepts and explains how the two technologies fit together.
What Containers Actually Solve
Traditional deployments rely on the host operating system’s libraries and configuration. That creates subtle differences between development, staging, and production environments — differences that surface as bugs at the worst possible time. A container packages an application together with its runtime, libraries, and configuration into a single image. That image runs identically whether it is on a developer laptop, a CI server, or a production cluster.
