Topic Node

Docker Volumes and Persistent Storage — Volumes, Bind Mounts, and tmpfs

Manage persistent data in Docker using named volumes, bind mounts, and tmpfs — and learn exactly which one to use for production vs development.

Topic Node

Docker Compose for Local Development — Full Stack in One Command

Build a complete local development stack with Docker Compose — API, PostgreSQL, Redis, and RabbitMQ — with hot reloading and clean config.

Start Guide

04

Topic Node

Docker Compose Health Checks and Dependency Ordering

Configure service health checks and correct startup ordering in Docker Compose so apps never start before their dependencies are ready.

Start Guide

Topic Node

Docker Compose in CI/CD Pipelines — GitHub Actions Integration

Use Docker Compose inside GitHub Actions to run integration tests against real databases, caches, and queues before every merge.

Topic Node

Docker Compose Production Patterns — Restart Policies, Resource Limits, and Env Config

Apply production-grade Compose patterns: restart policies, CPU/memory limits, environment separation, and config management for real deployments.

Start Guide

07

Topic Node

Docker CI/CD Pipeline — Build, Scan, Push, and Deploy with GitHub Actions

Build a complete Docker CI/CD pipeline: multi-stage builds, vulnerability scanning with Trivy, push to ECR, and zero-downtime deploy using GitHub Actions.

How to Reduce Your Docker Image Size by 80 Percent

A 1.2GB Node.js Docker image became 180MB with three changes. Here is exactly what was changed, why it worked, and how to apply the same fixes to any production image.

Vocabulary & Terms

Key words used in this concept — explained simply, no jargon.

Container

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.

Docker Image

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.

Container Registry

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.

Container Lifecycle

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.
