Kubernetes Implementation

Folder: .github/skills/tsh-implementing-kubernetes/ Used by: DevOps Engineer

Provides Kubernetes deployment patterns, Helm chart conventions, and cluster management best practices.

Deployment Patterns​

  • Deployments — Standard stateless workloads with rolling updates.
  • StatefulSets — Stateful applications requiring stable network identities.
  • DaemonSets — Node-level agents (monitoring, logging).
  • CronJobs — Scheduled batch workloads.

Resource Management​

ResourceApproach
RequestsSet to the average resource usage
LimitsSet to the peak resource usage with headroom
HPAConfigure horizontal pod autoscaling based on CPU/memory or custom metrics
PDBSet Pod Disruption Budgets to maintain availability during rollouts

Health Probes​

ProbePurpose
LivenessRestart the pod if the application is stuck
ReadinessRemove from service until the application is ready to serve traffic
StartupAllow slower startup for applications with long initialization

Security​

  • Run containers as non-root with read-only file systems.
  • Use NetworkPolicies to restrict pod-to-pod communication.
  • Configure RBAC with least-privilege service accounts.
