# otel-k8s
Quick start manifests for demonstrating OpenTelemetry on Kubernetes
## Kubernetes Deployment of OpenTelemetry Stack
This repo contains kubernetes manifests necessary to deploy the OpenTelemetry stack.
Mostly inspired from https://github.com/open-telemetry/opentelemetry-collector/blob/master/examples/demo/
- Load Generator
- deployment
- OpenCensus instrumented go application
- source: https://github.com/open-telemetry/opentelemetry-collector/blob/master/examples/main.go
- [omnition/synthetic-load-generator](https://github.com/Omnition/synthetic-load-generator)
- jaeger-emitter
- zipkin-emitter
- [freshtracks.io/avalanche](https://github.com/open-fresh/avalanche)
- prometheus metrics generator
- service
- `:9001/metrics` endpoint exposed through a service
- opentelemetry-agent
- daemonset
- receivers
- opencensus
- jaeger
- zipkin
- prometheus
- processors
- batch
- queued-retry
- exporters
- opencensus
- headless service
- `55678` for opencensus protocol
- `14268` for jaeger thrift api
- `9411` for zipkin proto
- opentelemetry-collector
- deployment
- receivers
- opencensus
- processors
- batch
- queued-retry
- exporters
- jaeger
- zipkin
- prometheus
- data sinks
- jaeger-all-in-one, exposed at `:14250`
- zipkin-all-in-one exposed at `:9411`
- prometheus
- scrapes opentelemetry service `:8889` for load-generator metrics
- scrapes opentelemetry service `:8888` for collector metrics
