Kubernetes (K8s)

Kubernetes, often shortened to K8s, orchestrates containerised applications. Studying container orchestration involves understanding how a desired state is described and how workloads are managed across a cluster. This is relevant to teams that deploy services, monitor their behaviour and organise application updates.

Pods, deployments and services provide useful starting points. Practical exercises can include publishing an application, reading its events and investigating why a workload restarts. Networking, storage, permissions and resource allocation need to be considered together rather than treated as an isolated list of settings.

A structured Kubernetes workflow includes testing changes, checking application health and documenting incidents. Before choosing an OO2 course, review your knowledge of containers, Linux and networking. Distinguish application development objectives from cluster administration tasks, and confirm which responsibilities and practical exercises the programme covers.
