  service: my-api
  backends:
    - service: my-api-v1
      weight: 900
    - service: my-api-v2
      weight: 100

Observabilita¶

linkerd viz dashboard
linkerd viz routes deploy/my-api
# NAME   SUCCESS  RPS  LATENCY_P50  LATENCY_P99
# my-api  99.8%   150  5ms          45ms

Summary¶

Linkerd = nejjednodušší mesh. mTLS + observabilita s minimální komplexitou.
