We are using Spring Boot, Spring Cloud Configurations and generate the application.yaml from an external source. This yaml file has about 53k lines of configuration and a file size of 2.7mb. Unfortunately, the spring application fails starting when connected to this config.

I managed to feed the yaml file into the Spring Cloud Config server locally and request a representation via a url like http://localhost:8888/mybranch/myApp-application.properties.

But when I start my Spring Boot app via mvn clean spring-boot:run -Dspring-boot.run.profiles=local it stops in the middle of the boot process.

In fact it stops after fetching the yaml from the cloud config server. As you can see it takes about 2 minutes to initialize the filter 'apiKeyHeaderFilter'. But after that it stops.

I already tried starting with the app with more heap size but same result: mvn clean spring-boot:run -Dspring-boot.run.profiles=local -Drun.jvmArguments="-Xms1024m"

Do I hit a size limitation or lines of config threshold with my setup?

Edit: Also the relevant part of myApp bootstrap.yaml looks like the following:

spring:
  profiles: local
  cloud:
    config:
      enabled: true
      label: mybranch
      uri: http://localhost:8888

  • Are you sure you setup config file correctly for your local env? – MS90 Mar 28 '19 at 20:47
  • Hi @MS90: When you say "setup config file" you probably refer to the `bootstrap.yaml` in the Spring Boot app, right? I am able to see the properties file via request to localhost after all. I firmly believe, the bootstrap is correct as I was able to change this to a different label and address a shorter application.yaml in a different branch. Let me edit the main post and add an extraction of the bootstrap.yaml. – M. Schmidt Mar 28 '19 at 21:47
