bootstrap.yml configuration not processed anymore with Spring Cloud 2020.0

Question

In my Spring Boot project, I defined 4 profiles

1. demo
2. dev
3. test
4. prod

properties in YAML files will be replaced by HashiCorp Vault properties during startup. For this, I use Spring Cloud Vault library. Everything works as expected in Spring Boot 2.3.x

When I try to upgrade the project to Spring Boot 2.4.0 with Spring Cloud Vault 3.0.0-SNAPSHOT version, the properties are not being replaced

bootstrap.yml

spring:   cloud:     vault:       authentication: APPROLE       app-role:         role-id: ${role-id}         secret-id: ${secret-id}         role: pres-read         app-role-path: approle       uri: ${vault-server}       connection-timeout: 5000       read-timeout: 15000       kv:         enabled: true         backend: secret         application-name: app/pres  

application.yml

spring:   config:     activate:       on-profile: 'demo' 

application-demo.yml

## Server Properties server:   port: 8081  spring:   datasource:     username: ${pres.db.username}     password: ${pres.db.password}     url: ${pres.db.url}  

Spring Cloud Vault Library

      <dependency>             <groupId>org.springframework.cloud</groupId>             <artifactId>spring-cloud-starter-vault-config</artifactId>             <version>3.0.0-SNAPSHOT</version>         </dependency>

Answer 1

As pointed put by Nicoll, With Spring Cloud Vault 3.0 and Spring Boot 2.4, the bootstrap context initialization (bootstrap.yml, bootstrap.properties) of property sources was deprecated. This can be fixed in one of the 2 ways

1. Use Spring Boot 2.4.0 Config Data API to import configuration from Vault (Preferred)
2. Legacy Processing: Enable the bootstrap context either by setting the configuration property spring.cloud.bootstrap.enabled=true or by including the dependency

<dependency>     <groupId>org.springframework.cloud</groupId>     <artifactId>spring-cloud-starter-bootstrap</artifactId> </dependency> 

1. Use Spring Boot 2.4.0 Config Data API (Preferred)

Move bootstrap.yml configuration to application.yml and updated file looks like below

application.yml

spring:   cloud:     vault:       authentication: APPROLE       app-role:         role-id: ${role-id}         secret-id: ${secret-id}         role: pres-read         app-role-path: approle       uri: ${vault-server}       connection-timeout: 5000       read-timeout: 15000   config:     import: vault://secret/app/pres/ 

And define individual profiles as shown below. Add spring.config.import: vault://secret/app/pres/demo property.

application-demo.yml

## Server Properties server:   port: 8081  spring:   config:     import: vault://secret/app/pres/demo   datasource:     username: ${pres.db.username}     password: ${pres.db.password}     url: ${pres.db.url}     driver-class-name: com.mysql.cj.jdbc.Driver 

Repeat the same process for all profiles like dev, test, qc, staging and prod.

2. Legacy Processing:

Add the following dependency if you still want to use bootstrap.yml

<dependency>     <groupId>org.springframework.cloud</groupId>     <artifactId>spring-cloud-starter-bootstrap</artifactId> </dependency> 

to the project. The issue will be resolved.

See Spring Cloud Vault docs for more information
