Conduit 0.4.1 builds on the telemetry work from 0.4.0, providing rich,
Kubernetes-aware observability and debugging.

  • Web UI
    • New Automatically-configured Grafana dashboards for Services, Pods,
      ReplicationControllers, and Conduit mesh health.
    • New conduit dashboard Pod and ReplicationController views.
  • Command-line interface
    • Breaking change conduit tap now operates on most Kubernetes resources.
    • conduit stat and conduit tap now both support kubectl-style resource
      strings (deploy, deploy/web, and deploy web), specifically:
      • namespaces
      • deployments
      • replicationcontrollers
      • services
      • pods
  • Telemetry
    • New Tap support for filtering by and exporting destination metadata. Now
      you can sample requests from A to B, where A and B are any resource or group
      of resources.
    • New TCP-level stats, including connection counts and durations, and
      throughput, wired through to Grafana dashboards.
  • Service Discovery
    • The proxy now uses the trust-dns DNS resolver. This fixes a number of DNS
      correctness issues.
    • The Destination service could sometimes return incorrect, stale, labels for an
      endpoint. This has been fixed!
