I have created 4 services Eureka service, Gateway service, Authentication service and User service. Authentication and User service are routing through gateway service on port 8000 and FeignClient is used to communicate between Auth and User service for creating user and authentication.
My services are running fine on local server but when docker images are created I'm getting a Feign retryable exception error.

I'm trying to add RabbitMq on my MSA project, but I have an issue with it.
I installed Erlang and RabbitMq, and rabbitMq Server is running with no problem.
The versions of Erlang is 25.0 and RabbitMq is 3.10.7.
This is rabbitMQ management webpage Image which is http://127.0.0.1:15672/
enter image description here
But when I run my Spring Boot Config server, server failed with connecting rabbitMq Server and keep trying attempting to Connect.
Here is the log.

It took me a while because I hate yaml but it should it's wrong.
this is the correct file:
server:

spring:
application:

JPA is its own node it's not under datasource.
Try this on you JPA config
spring:
datasource:
driver-class-name: org.postgresql.Driver

I'm trying to deploy a SpringBoot app in local with Kubernetes and Traefik, with local url.

What should I do to debug this ?
You have the spring application running with listening port 8081, this will not work.
2019-10-25 14:53:39.002 INFO 1 --- [ main] o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat initialized with port(s): 8081 (https)
Adjust your service to use target port 8081 instead of 8888
I'm prototyping something with Spring-Boot 1.2.7.RELEASE and Apache Ignite 1.4.0 and noticed something a little odd, maybe it's a just a logging configuration.
It looks like Apache Ignite is trying to start twice with Spring? If I comment out the SpringApplication.run line then it looks like it only starts once. Maybe I'm not using Spring with Apache Ignite correctly?

These are not "two instances", but two ways of how Ignite logs startup banner - one with STDOUT and another one with a built-in logger.
Just add ignite-slf4j dependency and use setGridLogger method of IgniteConfiguration to override the default logger - this message will disappear.
Actually Ignite starts once in both cases (with commented and uncommented SpringApplication.run line). Each Ignite node prints out current topology snapshot, but I see only one line about it in log:
