Get secret from hashicorp vault using java application with service token

Question

Maybe some could help me understand where I missed something.

I use such example to set-up cloud-config service, with another spring application which is used vault to get some secrets.

If I using root token everything is working correctly.

But once I create service token with policy

path "secret/data/test*" {
  capabilities = ["create", "read", "update", "delete", "list"]
}

path "secret/test*" {
  capabilities = ["create", "read", "update", "delete", "list"]
}

I can validate it with

$ vault token capabilities secret/test
create, delete, list, read, update

and with curl

$ curl \
--header "X-Vault-Token: $VAULT_TOKEN" \
http://<dns-name>:8200/v1/secret/data/test | jq .

{
  "request_id": "44b5fdcf-a13c-8e12-83f3-a5064f25257d",
  "lease_id": "",
  "renewable": false,
  "lease_duration": 0,
  "data": {
    "data": {
      "test-key": "test-value"
    },
    "metadata": {
      "created_time": "2020-04-09T21:11:28.899688798Z",
      "deletion_time": "",
      "destroyed": false,
      "version": 1
    }
  },
  "wrap_info": null,
  "warnings": null,
  "auth": null
}

but once I start using this token with the application it returns

2020-04-10 13:38:43.186 DEBUG 43843 --- [nio-8888-exec-1] org.apache.http.wire: http-outgoing-0 >> “GET /v1/secret/data/test HTTP/1.1[\r][\n]”

It really sounds like the app is not attaching the credentials correctly. Try hitting a site like httpbin . The /anything will return the request that it received. Its an easy way to debug those services.

You can also host that site locally if you are worried about those credentials.
