Containers package an application together with everything it needs to run, so it behaves the same on a laptop, in a pipeline, and in production. They are the unit that nearly every modern platform builds, ships, and runs.
You'll start with what a container is and how Docker works, then learn to write a Dockerfile and build lean, secure images. From there you'll run multi-container setups with Docker Compose, persist data with volumes, and publish images to a registry.
Next up is Kubernetes & Orchestration, where you'll run containers like these reliably at scale.
A fast overview of Docker: Dockerfiles, images, and containers, building and tagging images, security scanning, and pushing images to a registry.
A complete beginner course covering containers versus virtual machines, the main Docker commands, Docker Compose, Dockerfiles, private registries, and volumes.
