Test Endpoint


Flow would be like this:

Client -> kraker-info-gateway -> kraker-info-user-svc -> kraker-info-bookmark-svc

Tracing component interaction

Start kraker-info-zipkin modules and tracing information will be at endpoint:


Externalization of properties:

  1. Create a .yml file in kraker-info-config directory with application name. For example: kraker-info-config/kraker-info-user-svc.yml

  2. Update corresponding component using that property with @RefreshScope annotation which indicates that the property value injected needs to be fetched for new request. For example:

public class UserController {
    private String currentEnv;
  1. Once you change the value at .yml file, make POST request to the endpoint

to make sure those values are refreshed for the context.

Setup Redis server

Redis is being used for caching with client Jedis.

For Mac, install Redis with brew as
brew install redis

Start Redis-server with:

brew services start redis

If you do not want to start with brew, then you can start Redis server as:

redis-server /usr/local/etc/redis.conf

Check if redis is running:

redis-cli ping

Stop Redis-server:

brew services stop redis
For windows

Download and start server to enable caching.

Swagger UI

All endpoints are exposed via gateway service. So, swagger-ui for endpoints is at:

You can’t perform that action at this time.
