Platform terminology defined
Written guides that show you how to apply this concept in real projects.
Key words used in this concept — explained simply, no jargon.
A lightweight, isolated process running on a shared Linux kernel using namespaces and cgroups — providing filesystem, network, and process isolation without the overhead of a full virtual machine.
A read-only, layered filesystem snapshot that serves as the template for creating containers. Each layer represents a Dockerfile instruction and is cached and reused across builds to speed up image creation.
A service that stores and distributes Docker images. The registry serves as the central repository from which developers push built images and deployment systems pull them to create containers.
The sequence of states a Docker container moves through from creation to removal — created, running, paused, stopped, and dead — each triggered by specific Docker CLI commands or container exit events.
Docker Security and Production Practices covers a variety of key topic guides, including: Docker Image Security Scanning — Trivy, Snyk, and ECR Scanning, Running Docker Containers Securely — Non-Root Users and Capabilities, Docker Secrets Management — Avoiding Credentials in Images and Compose Files, Docker Production Logging — Log Drivers, Rotation, and Centralised Collection.
