I have application.yaml configuration file with few profiles:
server:
address: 0.0.0.0
port: 9090
db:
url: 'jdbc:postgresql://localhost:5432/the_db'
driver: 'org.postgresql.Driver'
username: 'postgres'
password: ''
---
spring:
profiles: devArtem
db:
url: 'jdbc:postgresql://localhost:5432/my_db'
---
spring:
profiles: prod_1
db:
password: 'first_pass'
---
spring:
profiles: prod_2
db:
password: 'second_pass'
And I want to remove other profiles before build jar file. I don't want to give access for prod_1's password to prod_2 platform for example.
For prod_1 it must be something like this:
server:
address: 0.0.0.0
port: 9090
db:
url: 'jdbc:postgresql://localhost:5432/the_db'
driver: 'org.postgresql.Driver'
username: 'postgres'
password: 'first_pass'
or this:
server:
address: 0.0.0.0
port: 9090
db:
url: 'jdbc:postgresql://localhost:5432/the_db'
driver: 'org.postgresql.Driver'
username: 'postgres'
password: ''
---
spring:
profiles: prod_1
db:
password: 'first_pass'
You can use multiple application-{profile}.yml and give each team the right file.
for example :
application-devArtem.yml ---> to team devArtem
application-prod_1.yml ---> to team prod_1
application-prod_2.yml ---> to team prod_2

I'm trying to configure the Eureka port with Spring Cloud with a eureka server, and config server (which is also a eureka client). Eureka service is successfully deployed and got a ip address. My Goal is to get the instance under eureka server.
I'm getting below error

As we can see from log above the configuration fetched successully. Perhaps config is wrong?
Problem was in classpath:/db.migration instead of classpath:/db/migration. Accidentally I'm create one folder.
I add new syntax in application.yml but failed.

- resources
- application.yml
- application-dev.yml

I have few microservices as :
APIGateway: common gateway for all requestwith zuul proxy
ConfigService: like config server for properties files
RegistryService: service registry with eureka server
HomePageService: 1 service registered with eureka and config-service
ProductService: 1 service registered with eureka and config-service
When I ran in local like order:
RegistryService->ConfigService THEN all services APIGateway, HomePageService, ProductService, its working fine.
Now i created docker images by providing config and run in docker container and pushed to GCR.
I have created account for google cloud(free for 1 Yr) and able to see images in repo.
All fine BUT how can I deploy those images in GKE. I ran individually and deploying but no linking. What is the way to deploy those services?
kubectl run service-registry --image=gcr.io/salesstock/service-registry:v1 --port=7002
kubectl expose deployment service-registry --name=service-registry --type=LoadBalancer --port=7002 --target-port=7002
I tried something and shared some code snipet.

FROM openjdk:8
EXPOSE 7003

ENTRYPOINT ["java","-Dspring.profiles.active=docker", "-jar", "homepage-service.jar"]
You deploy Docker containers by defining the container in the podspec of the k8s resource. You are already doing this with the kubectl run commands.
You then expose the pods using services, this is what you are doing with kubectl expose (the default value for this is ClusterIP, which is perfect for inter pod communication)
The reason this is not working for you is the way each container is trying to reach other containers. Localhost won't work. the IP you are using (192.168.x.x) likely isn't working either.
Instead, configure each container to target the FQDN of the corresponding service.
Example:
RegistryService->ConfigService
Expose the ConfigService using a ClusterIP service (if you use kubectl expose, the name will be ConfigService).
Configure the RegistryService to look for the ConfigService using "ConfigService.default.svc.cluster.local"
