# A full flegde example for Distributed Tracing

This Repository contains two micro-services in which tracing agent is integrated.

I am using ZipKin, a Open Source tracer for demonstration.

## Prerequisites

    1. GO 1.13+

    2. Docker

## Services -

 1. Employee Service - This is a demo service performs CRUD operation for employee.

 2. Auth Service - This service creates and checks Auth for employee service APIs.

## Employee flows




 




In both of the flows employee service interacts with auth service using REST APIs.

## Demo

## Perform below actions to run this demo -


    docker run -d -p 9411:9411 openzipkin/zipkin 

    cd auth

    go run main.go

    cd ..

    cd employee

    go run main.go

## Blow are the cURL to perform employee action

### 1. Employee Registration

#### Request -

    curl --location --request POST 'localhost:8080/employee' \

    --header 'Content-Type: application/json' \

    --data-raw '{

        "name":""

    }'

#### Response - 

    {

    "id": ""

    }

    

### 2. Get Employee details

#### Request -

    curl --location --request GET 'localhost:8080/employee?id=' \

    --header 'Authorization: ' \

    --header 'Content-Type: application/json'

#### Response - 

    {

        "employee": {

            "id": "",

            "name": "your name"

        }

    }

### 3. Open ZipKin dashboard using below URL to see trace generated
