K8s load testing at scale with k6-operator
summary
Uses k6-operator to run distributed k6 tests inside the cluster, with JavaScript test scripts compiled to Go, integrated into GitHub Actions to deploy two image versions and run parallel runners (parallelism 4) in the same namespace as production. Shows k6-operator plus chaos-capable xk6-disruptor, compares two builds and finds a staggering performance delta (3.7 RPS → 47,000 RPS), and documents an S3 load experiment that cost about $1,000 and revealed provider throttling.
