Join over 510 students who have already leveraged this course to elevate their Kubernetes expertise and transform how they manage their custom applications at scale.
Requirements / Prerequisites
- Proficient Kubernetes Fundamentals: A strong working knowledge of Kubernetes concepts is essential, including pods, deployments, services, ingresses, volumes, namespaces, and basic `kubectl` command-line operations. You should be comfortable interacting with a Kubernetes cluster and understanding its core resource model.
- Solid Go Programming Experience: Since the Operator SDK primarily leverages Go, an intermediate-level understanding of Go programming language, including concurrency, interfaces, structs, and error handling, is a mandatory prerequisite. While not exhaustive, foundational knowledge will be heavily utilized throughout the practical exercises.
- Understanding of Cloud-Native Architecture: Familiarity with microservices architecture, twelve-factor app principles, and the challenges of managing distributed systems will provide valuable context for understanding the problems Operators solve.
- Linux Command Line and Shell Scripting: Competency in navigating a Linux environment, using standard command-line utilities, and basic shell scripting will be beneficial for cluster management and automation tasks.
- Version Control with Git: Experience with Git for source code management, including branching, merging, and pull requests, is expected as it’s an integral part of modern software development workflows.
- Containerization Basics (Docker/containerd): A good grasp of container images, Dockerfiles, building container images, and pushing them to a registry is required, as Operators are deployed as containers within Kubernetes.
- Development Environment Setup: Access to a suitable development environment (e.g., Docker Desktop, Minikube, Kind, or a managed cloud Kubernetes cluster) is crucial for hands-on practice.
Skills Covered / Tools Used
- Custom Resource Definition (CRD) Design and Implementation: Learn to define Kubernetes’ API extensions through CRDs, including schema validation, versioning strategies, and status subresources for robust custom resource management.
- Developing Custom Controllers: Master the creation of sophisticated custom controllers that watch for changes in CRDs and other Kubernetes resources, enabling your Operator to react intelligently to desired state changes.
- Utilizing Operator SDK: Gain expertise in using the Operator SDK framework for scaffolding new Operator projects, defining APIs, generating boilerplate code, and simplifying the development lifecycle of production-grade Operators.
- Implementing Advanced Reconciliation Loops: Dive deep into building idempotent, resilient, and fault-tolerant reconciliation logic, including effective error handling, event generation, and managing complex application lifecycles.
- Packaging and Deployment Strategies for Operators: Understand how to containerize your Operators, create deployable manifests, and explore advanced deployment mechanisms like the Operator Lifecycle Manager (OLM) and Helm.
- Comprehensive Testing of Operators: Develop strategies for unit, integration, and end-to-end testing of your Operators, ensuring reliability and correctness across various Kubernetes environments.
- Debugging and Troubleshooting Operators: Acquire practical skills in diagnosing and resolving issues within Operator code, utilizing logging, Kubernetes events, and introspection techniques to understand controller behavior.
- Applying Operator Best Practices: Learn industry-standard practices for secure Operator development, performance optimization, scalability considerations, and maintaining observability through metrics and structured logging.
- Managing Stateful Applications with Operators: Explore advanced patterns for Operators to manage complex stateful applications, including database provisioning, backup and restore operations, and rolling updates.
- Tools Used: `kubectl`, `operator-sdk CLI`, `GoLand` or `VS Code` (as IDEs), `minikube`/`kind` for local cluster setup, `Docker`/`containerd` for containerization, `Prometheus`/`Grafana` for observability examples, `Helm` for packaging.
