DevOps
Helm charts are complex Go templates that generate Kubernetes manifests. A chart that lints cleanly can still produce broken YAML, silently wrong values, or manifests that fail admission webhooks. This guide covers the full testing stack: helm lint for static analysis, helm template for manifest inspection, chart-testing (ct) for
Chaos Engineering
LitmusChaos is a CNCF-graduated chaos engineering platform built natively for Kubernetes.
SRE
Chaos engineering is the practice of deliberately introducing failures into a system to discover weaknesses before they cause incidents.
Testing
Testing Kubernetes workloads against mocked APIs or unit-tested controllers misses an entire class of bugs — the ones that only appear when your pods, services, ingresses, and RBAC rules interact with a real API server. Running E2E tests against actual clusters in CI used to require expensive dedicated infrastructure. Lightweight
Testing
Kubernetes operators are some of the most complex software in a typical infrastructure stack — they implement reconciliation loops that must handle partial failures, retries, status conditions, and concurrent updates correctly. Testing them requires more than unit tests with mock functions. You need to exercise the full controller machinery: the informer
