Docker container can not fetch configuration from bitbucket

Question

I have a EurekaService and a CloudConfigService (I have other 3 services; but let's focus on the CloudConfigService).

CloudConfigService looks like this -

@EnableEurekaClient
@EnableConfigServer
@SpringBootApplication
public class CloudConfigServiceApplication {

    public static void main(String[] args) {
        SpringApplication.run(CloudConfigServiceApplication.class, args);
    }

}

application.yml -

server:
  port: 9296

spring:
  application:
    name: config-server
  cloud:
    config:
      server:
        git:
          uri: https://[email protected]/erfan_ahmed/config-server-erfan.git
          clone-on-start: true
          default-label: master

This is how the application.yml of ../config-server-erfan.git looks like -

eureka:
  client:
    register-with-eureka: true
    fetch-registry: true
    service-url:
      defaultZone: http://eureka:8761/eureka/
  instance:
    hostname: eureka

Dockerfile-

FROM openjdk:8-jdk-alpine
#ARG JAR_FILE=target/*.jar
COPY /build/libs/cloud-config-service-0.0.1-SNAPSHOT.jar app.jar
ENTRYPOINT ["java","-jar","/app.jar"]

After building image out of it, when I run the container using following command -

docker run -d --name cloud -p 9296:9296 --network my-network cloud

I get the following error -

c.n.d.s.t.d.RedirectingEurekaHttpClient : Request execution error. endpoint=DefaultEndpoint{ serviceUrl='http://localhost:8761/eureka/}, exception=I/O error on GET request for "http://localhost:8761/eureka/apps/": Connect to localhost:8761 [localhost/127.0.0.1] failed: Connection refused (Connection refused); nested exception is org.apache.http.conn.HttpHostConnectException: Connect to localhost:8761 [localhost/127.0.0.1] failed: Connection refused (Connection refused) stacktrace=org.springframework.web.client.ResourceAccessException: I/O error on GET request for "http://localhost:8761/eureka/apps/": Connect to localhost:8761 [localhost/127.0.0.1] failed: Connection refused (Connection refused); nested exception is org.apache.http.conn.HttpHostConnectException: Connect to localhost:8761 [localhost/127.0.0.1] failed: Connection refused (Connection refused)

Instead of hitting http://eureka:8761/eureka/, CloudConfig always send get request to localhost:8761. Thus causing the error.

Update 1

I found out that, from inside the container CloudConfig can not fetch config form git - https://[email protected]/erfan_ahmed/config-server-erfan.git. That's why it falls back to default localhost.

I put the config from git into the application.yml file and it works.

So, why it can't fetch config from git url?
