What is bootstrap yaml in spring boot?
And could you advise where I can use it?
bootstrap.yml is used in spring cloud
It is starting before application.yml
It is almost use with spring cloud config server
Spring cloud config server is server which is used to externilize your application configuration.
And when starting your application bootstrap.yml will take the configuration from spring cloud config server.
It also can use encrypting and decrypting some information by :
'{cipher}someyour encoded text'
and server will decode it while pulling the configurations
But you need to create jks
You can reach the documentation for more information about spring cloud :
https://spring.io/guides/gs/centralized-configuration/
Configuration files in spring boot will be loaded in such order:
1. src/main/resources/bootstrap.yml
2. src/main/resources/application.yml
3. config/application.yml

I'm using the Azure key vaults just follow this doc.
and spring cloud config server ,
i put the configurations of key vaults in spring cloud config
but found out when application start, the Azure key vaults is load before spring cloud config
so means i can not get the azure configs in spring cloud.
is there a way to change the load sequence?
make the spring cloud configs load in firstly
I have a spring cloud project. There are config server (config-srv), eureka server (eureka-srv) and some other service with business logic, let's call it main service (main-srv).
I'm packaging them into jars and run one by one. My apps get their properties from a file in the same directory with jars.
So, I'm setting properties to config-srv through "application-native.properties".
But if i want to change config-srv url (for example, i want http://localhost:9999), how can i share this url for all micro-services before they will boot ? I'm trying to share this url in "application-default.properties" but it makes no effect.
You can put the Spring Cloud Config server details in bootstrap.properties file in each microservices.
spring.application.name=microserviceName
spring.profiles.active=dev
spring.cloud.config.uri=http://localhost:9999
spring.cloud.config.username=your_username
spring.cloud.config.password=your_password

What is the difference between the followings?
Spring Cloud Vault - http://cloud.spring.io/spring-cloud-vault/
Spring Cloud Config Server with Vault backend - http://cloud.spring.io/spring-cloud-static/Camden.SR4/#_spring_cloud_config_server
Spring Cloud Vault is more lightweight because it does not require to run a java server (Spring Cloud Config Server) as a frontend for Vault, your Spring Boot app connects directly to Vault.
I have a small demo: https://github.com/gmarziou/demo-spring-cloud-vault
I'm having a problem with how to use just Netflix Archaius to work as a config server for multiple Spring Boot microservices. Previously when I applied Eureka and Spring Cloud Config Server in my multiple-services project built with Spring Boot, each microservie would get its own .properties file from the Spring Cloud Config server through the discovery function of the Eureka service. But now I need to change the Spring Cloud Config Server into a Netflix Archaius service, from which the Spring Boot microservices will get .properties file, i have no idea about how to achieve it. Is there any good idea for my reference? Thanks in advance.
Finally I gave up using Netflix Archaius to pull properties file for microservices. Instead, I wrote down required key-value-pair properties into the application.properties of each springboot microservice. Since all the springboot microservices will be deployed in the DCOS platform in the form of docker containers, some inconstant properties were configured into the marathon deployment scripts, which could be populated into the springboot applet. In this way I managed to configure the key-value-pair properties from the outside instead of being hardcoded in the program codes.
I'm just curious, is it possible to consume Spring Cloud config by a Spring REST service which is not a Spring boot application. If it is possible, where to define the properties in a Spring REST service. I meant, where should I define
spring.cloud.config.uri etc.
Or, only Spring boot applications are allowed to consume Cloud configuration?
Any thought would be appreciated. Thanks
well spring boot just bootstrap all configuration automatically . so for simple spring application you have to config it manually and define the cloud config server beans in your application configuration file . it could be pure old fashion xml files or just using java code configuration with #Configuration. you could find some samples in github
