Spring REST Application with Microservices

Question

I got this Spring Boot application that is now impossible to run standalone in development mode. It is configured to use Consul as service discovery. It works just fine when in a Docker container along with a Consul container (named as "consul-master"), however it will not start when I run from the IDE:

In a try to have it run on development mode ("dev" profile with --spring.profiles.active=dev ), I used the following config ( bootstrap-dev.yml ): 

spring:
  cloud:
    consul:
      enabled: false

The result is an exception that I don`t really understant how to fix:

In addition to that, I even tried to manually set a list of servers for FeignClient on application.yml :

When you run your service with docker and consul, it is registered to consul as it has its entry in docker-compose.yml file and registering part happens but we don't exactly see that. So you don't face any issues but when you run it through IDE you don't have it registered with consul therefore it throws UnknownHostException .

Basically you need to register your service to consul for its discovery.

I did it with following command,

curl -X PUT -H 'application/json' -d '{"Node": "yourServiceName", "Address":"yourHost.com", "Service": {"Service": "yourServiceName", "Tags": ["proxy"], "Port": 8080}}' http://yourHost/v1/catalog/register

Note:

1.mention correct port and names.

2.run this above mentioned command from location where docker-compose.yml is present

Also you can refer Consul Getting Started and Consul Catalog API to get help for registering your locally running service to consul as above command is specific to my requirements by may not be suitable for yours.

Hope it helps !

The result of your dev profile usage: 

java.lang.ClassNotFoundException: org.springframework.cloud.netflix.ribbon.SpringClientFactory

just tells that you're missing that dependency in your app. Probably the app is configured in a way that those client libs are not loaded using dev profile - but then app doesn't provide any alternatives. You need to fix the app to either provide the library also on dev profile or, for example, mock that dependency out.
