A structured, production-focused learning hub for DevOps and modern infrastructure engineering.
Start learning · Explore the repository · Build projects · Contribute
DEVOPS-WORLD helps you understand how modern systems are built, delivered, secured, observed, and operated. It connects individual tools to the engineering decisions behind reliable production systems.
The repository covers:
- Linux, networking, Git, and scripting
- Cloud platforms and infrastructure as code
- Docker, Kubernetes, Helm, and GitOps
- CI/CD, release engineering, and automation
- Monitoring, logging, tracing, and incident response
- DevSecOps, platform engineering, SRE, and production operations
- Hands-on projects, troubleshooting scenarios, and interview preparation
This is not a list of tools to memorize. The goal is to learn how systems behave, how they fail, and how engineers operate them responsibly.
| If you are... | Use DEVOPS-WORLD to... |
|---|---|
| New to DevOps | Follow the learning path in order and complete the labs |
| Building a portfolio | Create production-style projects and document your decisions |
| Preparing for interviews | Review concepts, scenarios, troubleshooting, and system design |
| Already working in infrastructure | Use the handbooks, incident cases, and reference material |
| Contributing to open source | Improve technical accuracy, labs, documentation, and diagrams |
Follow the stages in order if you are new. If you already have experience, start at the stage that matches your current gap.
| Stage | Focus | Outcome |
|---|---|---|
| 1 | Linux, networking, Git, Bash, Python, YAML, JSON | Work confidently from the command line and understand system fundamentals |
| 2 | Cloud, web servers, databases, Docker | Build and run foundational infrastructure and containerized applications |
| 3 | Terraform or OpenTofu, Ansible, CI/CD | Provision infrastructure and automate delivery |
| 4 | Kubernetes, Helm, managed Kubernetes, GitOps | Deploy and manage containerized workloads at scale |
| 5 | Metrics, logs, traces, alerting, SRE | Observe systems and measure reliability |
| 6 | Availability, scaling, incidents, recovery | Operate and troubleshoot production systems |
| 7 | IAM, secrets, supply-chain security, policy as code | Apply security throughout the delivery lifecycle |
| 8 | Platform engineering, FinOps, governance, AIOps | Explore advanced infrastructure specializations |
- Computer fundamentals
- Linux
- Networking
- Git and GitHub
- Bash and shell scripting
- YAML and JSON
- Python for automation
Choose one tool when several tools solve the same problem. Learn the principle first, then learn another tool when a project or role requires it.
Foundations → Cloud → Containers → Infrastructure as Code → CI/CD → Kubernetes → Observability → Security → Production Operations
At every stage:
- Learn the concept.
- Build a small working system.
- Verify its behavior.
- Break it deliberately.
- Troubleshoot with evidence.
- Document the failure and recovery.
- Explain what would change in production.
DEVOPS-WORLD is organized by purpose so you can find the right depth quickly.
| Area | What to expect |
|---|---|
| Learning resources | Structured concepts, commands, examples, and foundational lessons |
| Projects and labs | Guided builds with verification, failure testing, and cleanup |
| Engineering handbooks | Focused references for tools, platforms, and operational practices |
| Troubleshooting | Symptom-led diagnosis, evidence collection, fixes, and prevention |
| Production incidents | Realistic failure scenarios, investigation paths, and lessons learned |
| Interview preparation | Technical questions, scenarios, system design, and practical exercises |
Repository sections are expanded continuously. Some topics may be planned or under active development.
A strong project should show more than a list of successful commands. Where relevant, include:
- The problem and intended outcome
- Architecture and major decisions
- Prerequisites and reproducible setup
- Configuration and commands
- Expected output and verification checks
- Security and cost considerations
- Common mistakes and failure scenarios
- Troubleshooting evidence and recovery steps
- Production trade-offs
- Cleanup instructions
Use the project as evidence that you can reason about a system, not only deploy it.
Ask these questions while you learn:
- What is happening inside the system?
- Why does this component exist?
- What depends on it?
- How can it fail?
- What evidence would reveal the failure?
- How would I contain, recover from, and prevent it?
- Would this approach be safe and maintainable in production?
Contributions are welcome when they improve accuracy, clarity, safety, or practical value.
Good contributions include:
- Correcting technical errors or broken links
- Improving explanations and diagrams
- Adding reproducible labs or troubleshooting cases
- Updating obsolete commands or practices
- Adding official documentation and trustworthy references
- Improving accessibility, navigation, and consistency

Do not open a public issue for a security vulnerability or accidentally exposed secret. Follow SECURITY.md instead.
For learning questions, bug reports, and repository help, see SUPPORT.md. Please use the correct issue template so maintainers have enough information to respond.
VERIQTA creates practical learning resources for DevOps, cloud, SRE, platform, infrastructure, production, and security engineering.
DEVOPS-WORLD supports that mission: learn the principle, build the system, investigate the failure, and understand the production trade-off.
If the repository helps you:
- Star it so you can return later
- Share it with another engineer
- Report outdated or incorrect material
- Contribute a focused improvement
- Build something with what you learn
Learn. Build. Break. Troubleshoot. Secure. Improve.
