Why Focus on Docker and Kubernetes?

Before diving into project ideas, let’s understand why Docker and Kubernetes remain at the heart of modern DevOps:

• Docker simplifies application packaging and delivery through containerization.
• Kubernetes orchestrates those containers, managing scalability, high availability, and self-healing.

These tools are not just trendy—they're foundational in modern infrastructure. Mastering them through meaningful DevOps project ideas will give you a huge advantage in any tech role, especially in SRE.

Top DevOps Projects for 2025

Here are some impactful and resume-worthy projects that use Docker and Kubernetes. Each project is designed to mimic real production challenges, helping you gain hands-on experience.

1. CI/CD Pipeline with Docker & Jenkins on Kubernetes

Set up a full continuous integration/continuous deployment pipeline using Jenkins inside Docker containers, deployed and orchestrated by Kubernetes.

Skills Covered:

• Jenkins pipeline creation
• Dockerfile writing and image optimization
• Kubernetes deployment and service configuration
• Rolling updates and rollback strategies

Why it matters:
CI/CD automation is at the core of DevOps. This project proves your ability to deliver reliable software at scale. Docker and Kubernetes Training

2. Microservices Application with Kubernetes Ingress

Develop a basic microservices-based application—like a shopping cart or blog platform—packaged into separate Docker containers. Deploy each service (e.g., user, cart, and product) in Kubernetes and expose them via Ingress.

Skills Covered:

• Docker Compose for local development
• Kubernetes pods, services, and Ingress
• Service discovery and load balancing
• Monitoring and logging with Prometheus + Grafana

Why it matters:
Microservices architecture is the future. This project demonstrates your understanding of distributed systems and production-ready configurations.

3. Self-Healing Systems with Kubernetes Probes

Design a system where faulty containers automatically restart using liveness and readiness probes. You can simulate failures and watch Kubernetes recover your services without manual intervention.

Skills Covered:

• Writing liveness/readiness probes
• Health checks and resilience engineering
• Kubernetes auto-restart and resource management

Why it matters:
SREs must build systems that “fail gracefully.” This project reinforces key reliability principles that employer’s value.

4. Serverless Kubernetes with Knative

Implement a simple serverless function (like an image resizer or Slack bot) using Knative on Kubernetes. Combine Docker to containerize your code and Knative for event-driven autoscaling. Kubernetes Online Training

Skills Covered:

• Dockerizing event-based applications
• Setting up Knative on Kubernetes
• Event triggers and autoscaling

Why it matters:
Serverless is gaining traction for on-demand computing. This project prepares you for the next-gen infrastructure demands.

5. Secure Kubernetes Cluster with RBAC and Secrets

Set up a secure Kubernetes environment using Role-Based Access Control (RBAC), Secrets management, and network policies. Integrate Vault or Kubernetes Secrets to store sensitive info.

Skills Covered:

• Kubernetes RBAC policies
• Managing Secrets securely
• Basic network segmentation with policies

Why it matters:
Security is critical in DevOps. Showcasing this project highlights your awareness of real-world security practices. Docker and Kubernetes Course
