Kubernetes: operate workloads and recover services

Objectives and progression

A six-module technical course with original Kubernetes application operations and support decisions. Learn to interpret rollouts, probes, destination selection, resource requests, persistent data, and permissions. Includes fictional APS scenarios, inspected v1.37 primary documentation, configuration-dependent limits, and an internal assessment of 24 decisions in 60 minutes.

Audience: APS L2/L3, infrastructure, SRE, systems administration teams, and technical managers.

Prerequisites: Application, monitoring, and production-support fundamentals; no bank-specific internal process assumed.

300 estimated study minutes

• Choose the execution unit and interpret change progress.
• Follow a connection path and distinguish readiness, startup, and restart.
• Interpret requests, limits, and placement constraints without blindly reducing capacity.
• Control configuration propagation and storage lifecycle.
• Distinguish API authorization from workload communication.
• Collect failure evidence and plan maintenance without bypassing availability.
