# dapr-tracing-demo
Dapr tracing demo integrating multiple self-container microservices (no dependencies) to illustrate end-to-end tracing where the tracing headers are being propagated across:
* service to service invocation
* input binding
* state operation
* pubsub subscribe
* output binding
## Prerequisites
* To run this demo locally, you will have to install [Dapr](https://github.com/dapr/docs/blob/master/getting-started/environment-setup.md).
* Additionally to view the resulting traces you will need Zipkin. Instructions on how to setup Zipkin for Dapr are [here](https://github.com/dapr/docs/blob/master/howto/diagnose-with-tracing/zipkin.md)
## Setup
Assuming you have all the prerequisites mentioned above, first, start by cloning this repo:
```shell
git clone https://github.com/mchmarny/dapr-tracing-demo.git
```
navigate into the `dapr-tracing-demo` directory
```shell
cd dapr-tracing-demo
```
and build the executables for your OS
```shell
bin/build
```
You should see now 4 files in the [dist](dist) directory: `producer`, `formatter`, `subscriber`, `sender`
## Run
Inside of the `dapr-tracing-demo` directory, start each one of the service individually:
### Formatter
```shell
dapr run dist/formatter \
--app-id formatter \
--app-port 8082 \
--components-path ./components \
--log-level debug \
--protocol http
```
### Subscriber
```shell
dapr run dist/subscriber \
--app-id subscriber \
--app-port 8083 \
--components-path ./components \
--log-level debug \
--protocol http
```
### Producer
```shell
dapr run dist/producer \
--app-id producer \
--app-port 8081 \
--protocol http \
--components-path ./components \
--log-level debug \
--port 3500
```
### Sender
> Sender is not a Dapr service, it will serve as a target for output binding
```shell
dist/sender
```
## Data
Now that all the services are running, send data by posting data to Dapr for the `receive` input binding
```shell
curl -X POST -d '{ "data": {"id":"1", "txt":"test"}, "operation": "create" }' \
-H "Content-type: application/json" \
"http://localhost:3500/v1.0/bindings/receive"
```
## Observability
http://localhost:9411/zipkin/
> Note, if your Zipkin isn't deployed in the `default` namespace you will have to edit the `exporterAddress` in [deployment/tracing/zipkin.yaml](deployment/tracing/zipkin.yaml)
## Status
### Service to service invocation
**Status**: ✅
**Description**: Trace parent populated and trace state empty as expected
```shell
traceparent: 00-6b0b8b04cfbde34f867cc52e68eaefae-7d4e118a07a9b590-00
tracestate:
```
## Input binding
**Status**: ❌
**Description**: Expected trace parent to be populated and trace state empty
```shell
traceparent:
tracestate:
```
## Pubsub subscribe
**Status**: ✅
**Description**: Expected trace parent and trace state to be populated
```shell
traceparent: 00-6b0b8b04cfbde34f867cc52e68eaefae-7d4e118a07a9b590-00
tracestate:
