Free DevOps Training: Learn CI/CD, Docker, and Kubernetes with Labs

The DevOps Skills Gap

DevOps is the highest-paying, fastest-growing discipline in tech. Median salaries exceed $130,000, and demand outstrips supply by a wide margin. Yet most DevOps courses remain theoretical — watch videos, read slides, maybe complete a multiple-choice quiz.

Hands-on DevOps training closes this gap by putting you inside real infrastructure.

What You'll Build in DevOps Labs

Docker Containerization — Build Dockerfiles, manage images, orchestrate multi-container applications with Docker Compose. Understand networking, volumes, and resource limits.

Kubernetes Orchestration — Deploy pods, services, and deployments. Scale applications, manage ConfigMaps and Secrets, and troubleshoot cluster issues.

CI/CD Pipelines — Set up automated build, test, and deployment pipelines. Learn GitHub Actions, Jenkins, or GitLab CI with real project workflows.

Infrastructure as Code — Write Terraform configurations, Ansible playbooks, or CloudFormation templates. Automate infrastructure provisioning and configuration.

Monitoring & Observability — Set up Prometheus, Grafana, and ELK stacks. Build dashboards, configure alerts, and analyze system metrics.

Why Docker Labs Are Essential

Docker is the foundation of modern DevOps. Before you can orchestrate with Kubernetes or automate with CI/CD, you need to understand containerization deeply.

Docker labs let you:

• Build images from Dockerfiles
• Manage container lifecycle (create, start, stop, remove)
• Configure networking between containers
• Persist data with volumes
• Debug container issues in real-time

Each lab is a sandboxed environment. Break something? Tear it down and start over. No consequences, maximum learning.

From Labs to Production

The skills you practice in labs directly transfer to production environments. Docker Compose files you write in labs follow the same syntax as production deployments. Kubernetes manifests work identically.

The difference is scale and risk. Labs remove the risk while preserving the complexity. You learn the same tools, the same patterns, and the same troubleshooting思维方式 — just in a safe environment.

Building Your DevOps Portfolio

Complete labs in order:

1. Docker fundamentals — Dockerfile, image management, container lifecycle
2. Docker Compose — Multi-container applications, networking, volumes
3. Kubernetes basics — Pods, services, deployments, scaling
4. CI/CD pipeline — Automated build, test, and deployment
5. Infrastructure as Code — Terraform or Ansible automation

Document your work. Screenshot your dashboards. Save your configuration files. This portfolio demonstrates practical skill to employers.
