Dependency

Java 21    
Spring Boot: 3.2.0
Spring Cloud: 2023.0.0  
Spring Vault: 4.1.0

Download and install Vault

Start vault server

$ server --dev --dev-root-token-id="00000000-0000-0000-0000-000000000000"

First, you need to set two environment variables to point the Vault CLI to the Vault endpoint and provide an authentication token.

$ export export VAULT_TOKEN="00000000-0000-0000-0000-000000000000" $ export VAULT_ADDR="http://127.0.0.1:8200"

Now you can store a configuration key-value pairs inside Vault:

$ vault kv put secret/vault example.username=estevam example.password=estevam

$ vault kv put secret/vault/cloud example.username=cloud_user example.password=cloud_password
