sys-token-store

Description

sys-token-store is a lightweight Ansible helper role for resolving, persisting, and injecting per-user application tokens in a unified and idempotent way.

It provides a single source of truth for application tokens while keeping runtime usage simple and consistent across roles.

The role is intentionally not a secret generator.
It only stores and propagates tokens that already exist (e.g. created by bootstrap processes or provided externally).

---

Core Principles

• Single logic for all roles
  • Always resolve tokens as: users → token store → empty
• No implicit token generation
  • Empty tokens are rejected
• Idempotent persistence
  • Store file is only rewritten when content actually changes
• Runtime injection
  • Tokens are always injected into the users fact for immediate use
• Case-sensitive keys
  • User keys and application IDs must match exactly

---

Token Resolution Order

When resolving a token, the following order is used:

1. users.<user>.tokens.<application_id>
2. Token store file (tokens.yml)
3. Empty string ('')

No automatic fallback generation happens.

---

Store Format

Tokens are stored in a single YAML file:

users:
  administrator:
    tokens:
      web-app-matomo: "46e50b0eb52d0d141a7d6cf9b3d0b3e2"

Default location:

/var/lib/infinito/secrets/tokens.yml

Permissions are restricted to root by default.

---

Provided Tasks

write.yml

Persists a token and injects it into the runtime users variable.

This is the canonical way to store tokens.

Input

• sys_token_store_user_key
• sys_token_store_app
• sys_token_store_token (must be non-empty)

Effects

• Updates the token store file (idempotent)
• Injects the token into users.<user>.tokens.<app>
• Exports sys_token_store_token

Empty tokens are rejected explicitly.

---

Usage Examples

---

Persist and inject a token

- include_role:
    name: sys-token-store
    tasks_from: write.yml
  vars:
    sys_token_store_user_key: administrator
    sys_token_store_app: web-app-matomo
    sys_token_store_token: "{{ matomo_token_value }}"

After this, the token is immediately available as:

users.administrator.tokens['web-app-matomo']

---

What This Role Does Not Do

• ❌ No token generation
• ❌ No encryption
• ❌ No user management
• ❌ No application-specific logic

It is a generic infrastructure helper.

---

Best Practices

• Keep all user and application keys lowercase
• Use stable application_id values
• Let application roles create tokens
• Let sys-token-store handle persistence and propagation
