Kjn developed Single Step Instrumentation (SSI) Target support for the Datadog Agent v2alpha1 API in the DataDog/datadog-operator repository. This work enabled users to define auto-instrumentation rules using pod and namespace selectors, along with tracer version and configuration options, streamlining observability across Kubernetes deployments. Kjn updated the Custom Resource Definition (CRD) and controller logic in Go and YAML to support these new target configurations. By reducing the need for manual instrumentation, this feature improved consistency and efficiency for users managing distributed tracing. The work demonstrated a solid understanding of API development, Kubernetes operator patterns, and controller implementation in Go.
