I'm attempting to run Spring Cloud Configuration Server, working through the examples in a book (Manning's Spring Microservices in Action), but updating to the latest versions: Java 17, spring-boot-starter-parent 2.6.1, with Spring Cloud 2021.0.0-RC1.
Each time I try to start the server, I get this error:
***************************
APPLICATION FAILED TO START
***************************
Description:
Invalid config server configuration.
Action:
If you are using the git profile, you need to set a Git URI in your configuration. If you have set spring.cloud.config.server.bootstrap=true, you need to use a composite configuration.
I am not using the git profile. I have tried two different profiles: native (with config files on the classpath) and vault (with a Hashicorp Vault server running locally). My latest /src/resources/bootstrap.yml contains the following:
spring:
application:
name: config-server
profiles:
active: vault
cloud:
config:
server:
vault:
port: 8200
host: 127.0.0.1
kvVersion: 2
server:
port: 8071
My best guess is that the bootstrap.yml file isn't getting picked up at server startup, and perhaps the git profile is a default. How can I remedy this?
OK, it looks like the problem here is that newer versions of Spring Cloud Configuration Server don't look for the bootstrap.yml file by default. There are a few different ways to solve it. The easiest is just to move all the properties to an application.yml/application.properties instead.
Another alternative is (found at NEWBEDEV here) is to include a dependency that implements the "legacy" bootstrap behavior:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>
