# Deployment Exceptions
|
|
|
|
This page documents known cases where an Ansible role deliberately skips its work instead of failing,
|
|
and explains the conditions under which the skipped work will be completed on a subsequent run.
|
|
|
|
## Matomo Token Not Yet Available
|
|
|
|
**Role:** [`roles/sys-front-inj-matomo`](../../../roles/sys-front-inj-matomo/)
|
|
**Variable:** `users.administrator.tokens['web-app-matomo']`
|
|
|
|
### Cause
|
|
|
|
The Matomo API token is generated during the Matomo bootstrap and persisted to disk by `sys-token-store`.
|
|
It is loaded into the `users` runtime variable at play start.
|
|
|
|
On the **first deployment** — or after a factory reset — the token does not yet exist because the bootstrap
|
|
has not run yet. A second common cause is that [`roles/sys-utils-service-loader/tasks/load_frontend_service.yml`](../../../roles/sys-utils-service-loader/tasks/load_frontend_service.yml)
|
|
skips `load_app.yml` when the
|
|
Matomo container is already reachable. In that case the container is healthy but the token file is still
|
|
absent from the token store, so the variable arrives empty.
|
|
|
|
### Behaviour
|
|
|
|
When `users.administrator.tokens['web-app-matomo']` is empty, `sys-front-inj-matomo` sets
|
|
`inj_enabled.matomo = false` for the current domain. This prevents the NGINX template from rendering
|
|
the Matomo body snippet (which would reference `matomo_site_id`) and skips `inject.yml` entirely.
|
|
The play continues without error.
|
|
|
|
Failing instead of skipping would make the play non-idempotent on first deployment and would block every
|
|
other application from being configured just because Matomo's bootstrap has not completed yet.
|
|
Matomo tracking is a best-effort enhancement, not a hard runtime dependency of the target application.
|
|
|
|
### Resolution
|
|
|
|
Once the Matomo bootstrap has run — either later in the same play or on the next Ansible invocation —
|
|
`sys-token-store` writes the token to disk. On the **next play run** the token is loaded at startup,
|
|
the condition evaluates to false, and `inject.yml` executes normally: registering the site at Matomo
|
|
and injecting the tracking code into the target application.
|
|
|
|
No manual intervention is required. Re-running the play is sufficient.
