How Docker 🐬 Works Explained
Docker is a platform that simplifies application development and deployment through containerization.
➡️ Here's a brief overview of how it works:
1. Developer: Writes code and prepares a Dockerfile with instructions to build an image.
2. Client: Uses Docker commands (docker build, docker pull, docker run, docker push) to interact with Docker.
3. Dockerfile: Script containing instructions to create an image, specifying base images and configurations.
4. Registry: Stores Docker images, which can be pulled or pushed by developers.
5. Docker Host: Runs the Docker daemon, managing images and containers.
6. Docker Daemon: Background service that manages the lifecycle of containers.
7. Images: Templates for creating containers, containing applications and dependencies.
8. Containers: Isolated environments where applications run, sharing the host system's kernel.
➡️ Workflow:
- Build: Developer creates an image from a Dockerfile.
- Push: Image is uploaded to a registry.
- Pull: Image is downloaded from the registry.
- Run: Container is created and started from the image.

In this article, we’ll explore a practical example of a Fully Serverless Architecture implemented using Terraform — a popular IaC tool and CI/CD implemented using GitHub Actions. The code repository we’ll be examining is hosted on GitHub
I have a NodeJS Cloud Native API which I have used to deploy in this architecture. This API is specifically designed to make use of AWS serverless services.
Following are the serverless services used in this project:

Writing a Kubernetes manifest isn't just about copying and modifying it. Security should be at the core.
This is just one example; there's much more to consider. You can't get this directly from the documentation. You have to dig deep and pull together the necessary information to produce a secure Kubernetes manifest.
