Docker compose - Cannot execute request on any known server - docker

Question

I have the following issue. I have two spring boot micro services (1.5.8 ver), a configuration service and a discovery service.
When I run them locally the services are starting and communicating successfully.
Now when I start this two services using a docker compose file I get the following error:
Request execution failed with message: java.net.ConnectException: Connection refused (Connection refused)

I have the following files:

I have tried many things but with no luck.
Can anyone suggest anything?
Thanks in advance

Answer 1

are you has been try set network each service ?
so, service config-svc and service discovery-svc communication through same network. try setup driver to bridge as follow
version: '3.4'
services:
config-svc:
image: "config-img"
container_name: config-svc
build:
context: ../config
dockerfile: docker/config.dockerfile
expose:
- "8888"
networks:
- app-network
discovery-svc:
image: "discovery-img"
container_name: discovery-svc
build:
context: ../discovery
dockerfile: docker/discovery.dockerfile
depends_on:
- config-svc
links:
- config-svc:config-svc
entrypoint: sh -c '/tmp/wait-for config-svc:8888 && java -jar discovery.jar'
expose:
- "8761"
networks:
- app-network
networks:
app-network:
driver: brige

Answer 2

Ok I found it. The problem was in the configuration service in the bootstrap.yml file the property value of spring.cloud.config.server.native.search-locations must be fixed to classpath:configs. Now it's working fine.
Thanks for your reply
