Up And Running

1. Start Jaeger Docker Image

   docker run -d -e COLLECTOR_ZIPKIN_HTTP_PORT=9411 \
   -p5775:5775/udp -p6831:6831/udp -p6832:6832/udp \
   -p5778:5778 -p16686:16686 -p14268:14268 -p9411:9411 \
   jaegertracing/all-in-one:latest

2. Start TraceMe Phoenix App

   This is the main application that retrieves available castles and their associated avatars

   You will need to run a local instance of Postgres and modify the db config to match your environment.

   cd traceme
   mix do deps.get, ecto.create, ecto.migrate
   mix run priv/repo/seeds.exs
   mix phx.server

3. Start Avatars Phoenix App

   This app simulate avatar generation.

   cd avatars
   mix do deps.get, phx.server
   

4. Open Jaeger UI

   Select the TraceMe service and observe the various spans associated with the api calls below.

     open http://localhost:16686

5. Exercise the tracing APIs

   # Regular call
   curl -XGET http://localhost:4000/api/castles
   # GenFlow call
   curl -XGET http://localhost:4000/api/castles_flow
   # External Avatar Service call
   curl -XGET http://localhost:4000/api/castles_svc
