Can't connect Spring Cloud Vault to HCP Vault in Dev Mode Using Token Auth

Question

What I have:

• HCP Vault in Development mode
• Simple Spring Client using Spring Cloud Vault
• CLI Client

Desried Outcome: Inject data into a variable using HCP Vault

What is working:

• Run Vault locally (in dev mode) and inject data into the variable
• Get the data from the HCP Vault using vault CLI

Notes:

• I'm generating the admin token to avoid the use of policies
• The secrets in HCP Vault and my local Vault are identical

This is my application.yml file:

spring.application.name: my-spring-boot-app


spring.cloud.vault:
  host: vault-cluster-public-vault-fjkdsahfdjksa.hfjksdfhdsajk.hashicorp.cloud
  port: 8200
  scheme: https
  authentication: TOKEN
  token: hvs.fdsjfhdsakjfhdasjkfhdasjkfhdasjkfhdasjkfhdasjkfhdasjkfhdsakj


spring.config.import: vault://

Answer 1

The problem was that I was missing the namespace header.

spring.cloud.vault:
  host: vault-cluster-public-vault-fjkdsahfdjksa.hfjksdfhdsajk.hashicorp.cloud
  port: 8200
  scheme: https
  namespace: admin
  authentication: TOKEN
  token: ${VAULT_TOKEN}

spring.config.import: vault://
