Spring Cloud Config Client multiple property files retrieve from same repo - spring-boot

I have a requirement to retrieve the property files with environment name distinguishing those.
Config server is listening to this repo (https://github.com/tpande1/spring-cloud-config-repo/tree/master) which has : config-client-dev.properties, config-client-sbx.properties, config-client-test.properties and config-client-prod.properties
In Client Server i have the below config to read from the above github repo. How can i read these different properties with the environment specified in my Client Application?
Sample Rest Code:
#GetMapping("/message") //Pick message(SBX, DEV, Test, PROD) from the propertyfile from github
public String getMessage() {
return message;
}
bootstrap.yml:
spring:
profiles: dev
application:
name: config-client
cloud:
config:
uri: http://localhost:1000 //Config server port
profile: sbx, dev, test, prod
management.endpoints.web.exposure.include: "*"

You can add multiple active profiles in your bootstrap yaml file. In the option where you have spring.profiles.active and in your config server, you can add search patterns for each profile.
As mentioned in the below link in Pattern matching section.

Profile based Spring Cloud Config Server client with optional local developer properties

My Goal:
Having the Spring Cloud Config Server import active and provide a way for developers to have an optional property file on their machine.
My Config Server is up and running using org.springframework.cloud:spring-cloud-config-server:3.1.3 and #EnableConfigServer on the main class. Http requests to the concrete endpoint yield the expected result. This server should provide important environment configurations for a developer for his/her local setup.
$ curl http://localhost:8888/test-application/dev
{"name":"test-application","profiles":["dev"],"label":null,"version":null,"state":null,"propertySources":[{"name":"classpath:/cfg/test-application/application-dev.yml","source":{"server.port":1111}},{"name":"classpath:/cfg/test-application/application.yml","source":{"server.port":8000}}]}
Where localhost:8888 is my Config Server and test-application ist the name of the client application (defined via spring.application.name). The provided dev is the currently active profile on the client (The dev profile indicates a locally running software, there is no dev environment).
Clients configuration:
application.yml
spring:
application:
name: test-application
config:
import:
- configserver:http://localhost:8888 # <- pull the configuration from the configserver
- optional:file:/absolute/path/to/the/project/root/ # <- if there are any additional configuration files, use them
The client uses the following dependencies:
org.springframework.boot:spring-boot-starter-web:2.7.0
org.springframework.cloud:spring-cloud-starter-bootstrap:3.1.3
org.springframework.cloud:spring-cloud-starter:3.1.3
org.springframework.cloud:spring-cloud-starter-config:3.1.3
As shown above, the "base" application.yml configured server.port=8000 where the profile specific is set to server.port=1111. When reading the documentation this behaviour is correct. But my local developer configuration contains server.port=2222. This was ignored.
Here comes the problem:
When starting the client application, i can see the following log statements:
Fetching config from server at : http://localhost:8888
Located environment: name=test-application, profiles=[default], label=null, version=null, state=null
Located property source: [BootstrapPropertySource {name='bootstrapProperties-configClient'}, BootstrapPropertySource {name='bootstrapProperties-classpath:/cfg/test-application/application-dev.yml'}, BootstrapPropertySource {name='bootstrapProperties-classpath:/cfg/test-application/application.yml'}]
The following 1 profile is active: "dev"
Tomcat initialized with port(s): 1111 (http)
Initializing Spring embedded WebApplicationContext
Tomcat started on port(s): 1111 (http) with context path ''
Started TestApplicationKt in 2.234 seconds (JVM running for 2.762)
The configuration evaluation result from spring was to choose port 1111 instead of the wanted 2222 within the application-dev.yml located in the project root (developer config).
Wrapped up:
Three config files:
config server application.yml (port: 8000)
config server application-dev.yml (port: 1111)
project root developer config application-dev.yml (port: 2222) <- I want this file to have precedence over the other two.
When running the debugger, i see these found property sources within the injected Environment bean. The wanted developer file is within this list and the property source content is correct (server.port=2222).
Does anyone have an idea how to solve this problem?
I have created a project that reproduces this exact behaviour. Link to GitHub.
Thanks in advance!
Is the dev profile active when application is running in dev environment or it's also active when running locally?
Ideally you should have 2 different profiles for dev and local and you can enable config server only when dev profile is active.
You can rename your local property file as application-local.yml and disable spring cloud config when profile local is active.
You can put below code in bootstrap.yml(create new file beside application.yml) and remove config server configurations from application.yml
---
spring:
application:
name: test-application
config:
activate:
on-profile: dev
import:
- configserver:http://localhost:8888 # <- pull the configuration from the configserver
- optional:file:/absolute/path/to/the/project/root/ # <- if there are any additional configuration files, use them
---
spring:
application:
name: test-application
config:
activate:
on-profile: local
cloud:
config:
enabled: false
EDIT: Actual fix
Thanks for sharing reproducible example.
All you need to do is remove local application-dev.yml location reference from client application.yml and add it to configServer application.yml as shown in belolow screenshots.
/client/src/main/resources/application.yml
And put it in configServer application.yml at the end of search-locations. Order matters so please make sure you put overriding location/s at the end.
/configServer/src/main/resources/application.yml
Build and start both the applications and you will see client application server started on port 2222

Spring Cloud Config - bootstraping compositie configuration

Is it possible to bootstrap spring config service with composite configuration.
Example:
Final configuration (placed on the git repo )
spring:
cloud:
config:
server:
composite:
- type: git
uri: <uri1>
- type: git
uri: <uri2>
After I setup env variable to bootstrap:
SPRING_CLOUD_CONFIG_SERVER_BOOTSTRAP = true
and provide setup to fetch configuration from repository spring config is not adding new configuration for additional repositories.
Is it possible to configure spring config server to bootstrap from one repository and then serve configuration from different one(s)?

Is there anyway to use configure-server with servlet context path when register on service discovery?

I have a service-discovery which register all the services. I have configure-server which maintain all the configuration. configure-server already register in service-discovery. I know by default configure-server will register with id: configserver. I know how to change the id. But when I tried to use servlet.context.path= /config all the configure-client can not pull from configure-sever through service-discovery look like can not use /config in configure-server.
configure-server:
server:
port: 0
servlet:
context-path: /config
spring:
application:
name: configserver
cloud:
config:
server:
git:
uri: https://github.com/PheaSoy/spring-completed-microservice
search-paths: config/{application}
discovery:
enabled: true
configure-client
spring:
application:
name: song-service
cloud:
config:
uri: http://configserver/config
discovery:
enabled: true
Even I added context path /path configure-client always fetched without context path.
ConfigServicePropertySourceLocator : Fetching config from server at : http://192.168.1.34:57945/
Is there any way to configure configure-client with available configure-server context path through service-discovery?
The discovery client implementations all support some kind of metadata map (for example, we have eureka.instance.metadataMap for Eureka). Some additional properties of the Config Server may need to be configured in its service registration metadata so that clients can connect correctly. If the Config Server is secured with HTTP Basic, you can configure the credentials as user and password. Also, if the Config Server has a context path, you can set configPath. For example, the following YAML file is for a Config Server that is a Eureka client:
bootstrap.yml.
eureka:
instance:
...
metadataMap:
configPath: /config
Reference:
Spring Cloud Config with Eureka - contextPath
Discovery with bootstrap
Yes, you can define your context path for your configuration server as you have done.
But doing so, you also need to take into account the alignments you need to do.
Eureka. By default will call your management API. For example, http://BASE_URI/actuator/health. But since you are adding a context path "config", it means it should be now: http://BASE_URI/config/actuator/health. You can correct following the suggestion above on eureka.instance...metadataMap.configPath: /config
Configuration Clients. In your application (client to the config server), you can add the context path in spring.cloud.config.uri. For example, if it was "http://BASE_URI", then it should be updated as "http://BASE_URI/config" now since you added a context path.
Please try and see if it helps.

Disabling config server for tests

I am using microservice architecture where the services are done with spring boot, to control them, I am using zuul as a proxy, eureka as register and config server as the configuration provider.
In the microservices I configure my bootstrap.yml file as follows:
spring:
application:
name: portal-gca-server-${MYENV:local}
cloud:
config:
uri: http://localhost:9090
As seen above, the config file name that I look for in the config server is according to my environment variable, otherwise I get the local profile.
This works fine, but when I run the tests on the development machine it will never work, because instead of searching for the test profile it searches for the location, because the dev machine has no environment variable.
I know I could register the environment variable to run the tests but that's not the intention or else I would have to do this all the time to run tests and to run the local application.
Is there any way to solve this? I already tried to use the annotations:
webEnvironment = SpringBootTest.WebEnvironment.MOCK
#ActiveProfiles("test")
#TestPropertySource(locations="classpath:application-test.properties")
None of them any good, because the first thing the application does when executed is to fetch the information in git according to bootstrap.yml.
Has anyone ever experienced this?
Go to your bootstrap.yml and then add :
spring:
cloud:
config:
enabled: false

How to create Spring Cloud Config Client with env specific configuration?

I have facing an issue with Spring Cloud Config Server and Eureka Server Profiling.
Let's say I have 3 services with their name ("spring.application.name") as :
myapp-svc
myapp-spring-cloud-config-svc
myapp-spring-eureka-svc
I want to deploy each service in 2 regions ( dev and prod ). In Dev region, each service will run on localhost and in prod it will have some different url. 'myapp-spring-cloud-config-svc' in dev region will point to local git repo, while in prod region it will point to remote git repo.I can have 2 configurations:
1) When I start 'myapp-svc' service in local, it should connect to 'myapp-spring-cloud-config-svc' in dev.
I can do this by setting spring.cloud.config.uri = .
But the issue with this set up is that the property needs to be defined in bootstrap.properties.
So, If deploy 'myapp-svc' to prod, I will have to change config uri there to point it to prod config service which in turn would need another build creation.
This doesn't seem like a good solution, what if I have 50 app related services, I can't change this property in each one of them before prod deployment.
I tried setting spring.cloud.config.uri in application-dev.properties of 'myapp-svc' but it doesn't work. As per docs, it must be changed in bootstrap.
So, how do I implement this without having to create new build for prod ?
2) I can first call eureka and then using eureka I can call config service here.
The problem here is also same.
If I use eureka to look up config then "eureka.client.serviceUrl.defaultZone" must be defined in "bootstrap.yml".
See this:https://cloud.spring.io/spring-cloud-config/multi/multi__spring_cloud_config_client.html
So, in this case too, I need to change eureka url before deploying this service to prod.
Please help me on this...!!
Here is how, the properties, yml looks like for each of the above mentioned services:
1) myapp-svc:
1.1)bootstrap.yml
spring:
application:
name: myapp-svc
cloud:
config:
discovery:
enabled: true
serviceId: myapp-spring-cloud-config-svc
eureka:
client:
serviceUrl:
defaultZone: http://localhost:8762/eureka/
server:
port: 8082
2) myapp-spring-cloud-config-svc:
2.1)application-dev.properties:
spring.cloud.config.server.git.uri=file:///C:/config-repo
eureka.client.serviceUrl.defaultZone=http://localhost:8762/eureka
2.2)application-prod.properties:
spring.cloud.config.server.git.uri=https://github.com/<mygit Repo>
2.3)bootstrap.proerties:
spring.application.name=myapp-spring-cloud-config-svc
server.port=8888
3) myapp-spring-eureka-svc
3.1)bootstrap.proerties
spring.application.name=myapp-spring-eureka-svc
server.port=8762
1) You can have profile specific bootstrap-<profile>.properties (like for application-<profile>.properties) for each supported profile to avoid rebuilding your application for each env. Then just pass application profile using to your application during start-up. Spring will load correct bootstrap-<profile>.properties and will connect to proper configuration server (or eureka, etc). Example:
java -jar your-app.jar --spring.profiles.active=dev
2) You can pass your URLs externally as custom properties (same as with profile above) and have smth like this in bootstrap.properties. Example:
spring.cloud.config.uri=${config.server.url}
then pass --config.server.url= ... during start-up.
3) You can pass Spring properties in the same way during start-up. Example:
java -jar your-app.jar --spring.cloud.config.uri= ...
4) You can use system env variables. Example:
spring.cloud.config.uri=${SYSTEM_ENV_CLOUD_CONFIG_URI}
