Kubernetes Cluster Administration
Learn how to maintain Kubernetes clusters through node maintenance, namespace controls, RBAC, secrets, config management, and workload troubleshooting. This course builds on Kubernetes basics and focuses on the administrative responsibilities behind keeping a cluster usable, secure, and organized.
Why It Matters
Running workloads on Kubernetes is only part of the job. Cluster administrators also need to control access, separate teams and resources, manage node lifecycle work, and diagnose failing workloads. These tasks define whether a cluster remains stable and governable as more users and applications rely on it.
What You Will Learn
- Perform node maintenance safely without disrupting workloads blindly.
- Use namespaces and quotas to separate and control cluster resources.
- Manage Kubernetes access through RBAC.
- Work with secrets and config maps for application configuration.
- Troubleshoot workloads that are not starting or behaving as expected.
- Apply these skills in a cluster rescue mission challenge.
Course Roadmap
The course begins with node maintenance so you can understand how administrators prepare nodes for repair or change while protecting workload continuity. It then moves to namespaces and quotas, which help organize cluster usage and control resource consumption.
Next, the course focuses on RBAC so access decisions are explicit and manageable. After that, you work with secrets and config maps, which are central to separating application configuration from workload definitions.
The final lab is dedicated to troubleshooting workloads, helping you identify why pods or controllers are failing before broadening the problem. The course ends with the Cluster Rescue Mission challenge, where maintenance, access control, configuration handling, and troubleshooting come together in a realistic administrative scenario.
Who This Course Is For
This course is for learners who already understand Kubernetes fundamentals and want to manage clusters with more administrative discipline.
Outcomes
By the end of this course, you will be able to perform basic Kubernetes administrative tasks, structure resource boundaries, manage access, handle configuration objects, and troubleshoot common cluster workload issues more effectively.
