# =============================================================================
# NetBird v1.6 - Instance Bootstrap
# =============================================================================
# Run ONCE on fresh deployment to:
#   1. Check if instance needs setup
#   2. Create initial admin user via API
#   3. Display instructions for manual PAT creation
#
# NOTE: The embedded IdP (Dex) does not support password grants,
# so PATs cannot be created programmatically without dashboard access.
# After this playbook, you MUST manually:
#   1. Login to dashboard with admin credentials
#   2. Create a service user
#   3. Generate PAT for service user
#   4. Store PAT in vault.yml as vault_netbird_service_pat
#
# Run:
#   ansible-playbook -i inventory.yml setup-bootstrap.yml --ask-vault-pass
# =============================================================================

          Bootstrap API Not Available (404)
          ============================================
          The /api/instance/setup endpoint returned 404.
          This means either:
            - Admin already exists, OR
            - This endpoint isn't exposed in your NetBird version

          Create admin manually in the dashboard:
            1. Go to: https://{{ netbird_api_host }}
            2. Create admin account:
               Email:    {{ netbird_admin_user.email }}
               Password: {{ netbird_admin_user.password }}

          Then create service user + PAT:
            3. Go to Team → Service Users → Create
            4. Generate PAT: Select user → Create Token
            5. Store in vault: ansible-vault edit group_vars/vault.yml
               Set: vault_netbird_service_pat: "<your-token>"

          Then provision users:
            ansible-playbook -i inventory.yml setup-groups.yml --ask-vault-pass

            User ID:  {{ bootstrap_result.json.user_id | default('N/A') }}

          ============================================
          MANUAL STEPS REQUIRED:
          ============================================

          1. Login to dashboard:
             https://{{ netbird_api_host }}
             (Accept self-signed certificate warning)

          2. Login with:
             Email:    {{ netbird_admin_user.email }}
             Password: {{ netbird_admin_user.password }}

          3. Create Service User:
             - Go to Team → Service Users
             - Click "Create Service User"
             - Name: "Automation Service"
             - Role: "Admin"
             - Save the user

          4. Create PAT for Service User:
             - Select the service user
             - Click "Create Token"
             - Name: "ansible-automation"
             - Expiration: 365 days
             - COPY THE TOKEN (shown only once!)

          5. Store PAT in vault:
             ansible-vault edit group_vars/vault.yml
             Set: vault_netbird_service_pat: "<your-token>"

          6. Run group and user provisioning:
             ansible-playbook -i inventory.yml setup-groups.yml --ask-vault-pass
             ansible-playbook -i inventory.yml setup-users.yml --ask-vault-pass
