Question
I'm trying to setup a simple microservice architecture based on Spring functionalities. I have 3 simple microservices as starting point: 1 Configuration Server (Spring cloud config) 2 Discovery Server (eureka server) 3 Gateway Zuul
I configure the services so that the discovery server store all the .properties file, it register itself to the discovery server so all other services retrieve the .properties file accessing the discovery not via static url but via eureka server.
My problem is, eureka-server has in the bootstrap.properties file the static url of the discovery and it can retrieve the file succesfully but the gateway didn't retrieve the file from the server. I have a the following error:
2020-03-24 16:49:32.287 INFO 43460 --- [ restartedMain] c.c.c.ConfigServicePropertySourceLocator : Connect Timeout Exception on Url - http://host.docker.internal:8081/. Will be trying the next url if available
2020-03-24 16:49:32.289 WARN 43460 --- [ restartedMain] c.c.c.ConfigServicePropertySourceLocator : Could not locate PropertySource: I/O error on GET request for "http://host.docker.internal:8081/gateway/default": connect timed out; nested exception is java.net.SocketTimeoutException: connect timed out
My configuration for the services is the following:
config :
- application.properties:
server.port=8081
spring.application.name=config
spring.cloud.config.server.git.uri=file:///${user.home}/application-config
eureka.client.region = default
eureka.client.registryFetchIntervalSeconds = 5
eureka.client.serviceUrl.defaultZone=http://localhost:8082/eureka/

the 2 files .properties stored in /application-config are the following
- discovery.properties
spring.application.name=discovery
server.port=8082
eureka.instance.hostname=localhost
eureka.client.serviceUrl.defaultZone=http://localhost:8082/eureka/
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
- gateway.properties
spring.application.name=gateway
server.port=8080
eureka.client.region = default
eureka.client.registryFetchIntervalSeconds = 5
zuul.routes.book-service.path=/book-service/**
zuul.routes.book-service.sensitive-headers=Set-Cookie,Authorization

The strange thing is that if after I start everything I try to access the gateway file from the browser calling http://host.docker.internal:8081/gateway/default I can retrieve the file but when the gateway starts he tries to retrieve the same file and It gaves my the error above:

If someone has my same problem I found the solution. It was due to my host file. I changed it once to fit with a VPN I worked and it map my ip with an ip I can't reach without the VPN on. Once I comment the file host everything works
