आप क्या सीखेंगे

  • Explain Kubernetes architecture and the declarative model of desired state and controllers.
  • Write Deployments, Services, ConfigMaps, Secrets, Jobs and CronJobs, and reason about label selectors.
  • Set resource requests and limits and predict how the scheduler places pods.
  • Configure probes, rolling updates and Horizontal Pod Autoscaling for reliable, scalable apps.
  • Package environments with Kustomize (and know when Helm fits), and manage storage for stateful apps.
  • Apply security and reliability basics: RBAC, securityContext, network policies and manifest linting.
