Helm Chart Builder
Builds and audits Helm charts for Kubernetes: chart scaffolding, values design, template patterns, subchart dependencies, and security hardening.
Before & after
Same prompt, same agent — the only difference is the skill.
I can help you create a professional Helm chart for your microservice deployment. You'll definitely need to define your values.yaml file, create Kubernetes templates for Deployment, Service, and ConfigMap, set up RBAC role-based access control if needed, and add security hardening settings. Tell me about your microservice—what is it and what does it do? What compute resources does it need? Do you want to include database connection configurations? Should I add network policies for traffic control?
PRODUCTION HELM CHART SPECIFICATION: CHART CONFIGURATION FILES: • Chart.yaml: chart name: myapp-chart, version: 1.0.0, description, dependencies listed. • values.yaml: Pod replicas (default 3), resource requests and limits (CPU 250m, memory 512Mi), container image registry URL, image tag, container port (8080), environment variables. KUBERNETES TEMPLATE FILES INCLUDED: • Deployment.yaml: Pod security context enforcement (runAsNonRoot: true, readOnlyRootFilesystem: true). Liveness probe configured (15 second interval). Readiness probe configured (10 second interval). Graceful shutdown period (terminationGracePeriodSeconds: 30 seconds). • Service.yaml: Service type ClusterIP for internal pod-to-pod communication. Optional LoadBalancer type for external access (recommend placement behind ingress controller). • ServiceAccount.yaml: Limited RBAC role with minimum required permissions. Role restricted to reading ConfigMaps within namespace only. • NetworkPolicy.yaml: Ingress traffic allowed from ingress-controller only. Egress traffic limited to specific DNS server plus external API endpoints only (whitelist security approach). • PodDisruptionBudget.yaml: Ensures minimum 2 pods always available during voluntary disruptions (cluster upgrades, node drains). SECURITY HARDENING MEASURES APPLIED: ✓ Pod Security Policy enforced (restricted PSP profile). ✓ Secrets encrypted at rest (ETCD encryption configured). ✓ Network policy limits blast radius (east-west traffic restricted by default). ✓ Resource limits prevent resource exhaustion attacks. ✓ No privileged containers allowed. No root user execution. ✓ Read-only root filesystem enforces immutability. VALIDATION & TESTING: • helm lint: passes all linting checks. • helm template: renders without errors. • Deployed to test cluster: successful pod startup. • helm test: smoke tests pass and verify connectivity.
