Docker compose run multiple services from yaml file. So that create docker-compose.yml file

docker-compose --version

196+
run from yml file

docker-compose up

203+
-http://localhost:8100/currency-conversion/from/USD/to/TRY/quantity/10 --> will not work.
204+
Because in controller response uri set as localhost. So you can change it
205+
using application.properties variable from docker image.!!
206+
207+
208+
209+
210+
NOTE: eureka url in currency-exchange-server's application.properties saved as
211+
eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka
212+
but localhost is not same currency-exchange-server container and naming-server container.
213+
so that you have to set as naming-server ip address or set environment in docker-compose.yml
214+
file to register naming-server.
215+
environment:
216+
EUREKA.CLIENT.SERVICEURL.DEFAULTZONE: http://naming-server:8761/eureka

---- With Rabbit MQ ------

What if Zipkin gone or not running? you should your trace in mq like rabbitMQ
168-
224+
What if Zipkin is gone or not running? microservices can put information to mq like rabbitMQ.
225+
226+
Normally zipkin sendr type have to define in application.properties as
227+
'spring.zipkin.sender.type=web' but default is web so that you dont have to define.
169228

229+
If you decide to use rabbit mq, you should set
230+
'spring.zipkin.sender.type=rabbit' or
231+
if you use docker container, you can define environment in yaml as
232+
'SPRING.ZIPKIN.SENDER.TYPE: rabbit
170233

234+
add rabbit mq server in yaml to run RABBIT MQ in docker container.
235+
236+
Also add rabbit mq settings to environment in yaml file.
