Dockerization

Introduction

This rulebook defines Stakpak’s standard procedure for securely and efficiently containerizing applications, ensuring maintainable deployments through:

  • Analysis

  • Documentation

  • Security best practices.

Goal

Why did we make this rule book?

  • To avoid insecure or inconsistent Docker configurations

  • To prevent inefficient builds and deployments

  • To eliminate the lack of documentation during containerization

What will you achieve?

  • Reliable, production-ready containers

  • Clear, repeatable workflows

  • Reduced operational risk and faster delivery

Who is this for?

Developers, DevOps engineers, and operations teams involved in building, deploying, or maintaining containerized applications

Workflow

The Stakpak Agent follows this standardized process to containerize applications securely and efficiently, ensuring consistent results across environments.

  1. Analyze: Review application structure, dependencies, and required external services.

  2. Select Base Image: Choose official, minimal, and regularly updated images for security and performance.

  3. Create Dockerfile: Implement multi-stage builds, run as a non-root user, and include health checks.

  4. Configure Docker Compose: Define services, networks, volumes, environment variables, and secrets.

  5. Build & Run: Build images with proper tags, use .dockerignore, start containers, and verify logs.

  6. Verify Health: Test endpoints, confirm service connectivity, and monitor resource usage.

  7. Clean Up: Remove unused containers, images, volumes, and clear build cache.

  8. Document: Record environment variables, secrets, deployment steps, and troubleshooting notes.

Use Cases
