Intro

1. From HTTP to API

   • Understand the transition from traditional HTTP-based services to modern API-driven architectures.
   • Learn about REST, gRPC, and GraphQL APIs.

2. Monolith to Microservice

   • Explore the migration from monolithic applications to microservices.
   • Understand the benefits of microservices, such as scalability, resilience, and maintainability.
   • Learn about strategies for breaking down monolithic applications into microservices.

3. Cattle not Pets

   • Embrace the concept of treating servers as disposable resources (cattle) rather than unique entities (pets).
   • Understand the benefits of immutable infrastructure and automated deployments.

4. Infrastructure as Code

   • Explore tools like Terraform, Ansible, and Kubernetes for defining and managing infrastructure.
   • Understand the principles of version control, repeatability, and scalability in infrastructure management.
   • Learn about managing infrastructure using code and automation tools.

5. Continuous Integration (CI)

   • Learn about CI practices and tools to automate testing and deployment.

Understanding K8s

1. Containers 101

   • Introduction to container technology, its benefits, and how it differs from traditional virtualization.
   • Learn about Docker, container lifecycle, and basic commands.

2. Kubernetes Architecture

   • Detailed overview of Kubernetes architecture and its components.
   • Understand the roles of the master node, worker nodes, and key concepts like pods, services, and deployments.

Using K8s in the Real World

1. Scaling with HPAs
   • Learn about Horizontal Pod Autoscalers (HPAs) and how they help in scaling applications dynamically.

Reference

1. Lexicon
   • A glossary of terms and concepts related to Kubernetes and cloud-native infrastructure.

Continuous Integration (CI)

This repository uses GitHub Actions for Continuous Integration (CI) to ensure code quality and consistency. The CI pipeline includes the following checks:

1. Markdown Linting

   • Uses markdownlint-cli to lint all Markdown files in the repository.
   • Ensures that Markdown files adhere to a consistent style and format.

2. Spell Checking

   • Uses cspell to check for spelling errors in Markdown files.
   • Helps maintain the quality and readability of documentation.

3. Link Checking

   • Uses markdown-link-check to verify that all links in Markdown files are valid.
   • Ensures that documentation does not contain broken links.

The CI configuration can be found in the .github/workflows/Doc-ci.yaml file.
