tutor-contrib-maintenance 1.0.0

Installation

pip install git+https://github.com/Abstract-Tech/tutor-contrib-maintenance

How it works

The plugin ships a small Caddy-based static-site image (its own Caddyfile, maintenance.html, and style.css) that runs alongside the platform as a maintenance service.

tutor maintenance on and tutor maintenance off don’t patch the main apps/caddy/Caddyfile at all. Instead they hot-swap the running Caddy config through its admin API (http://127.0.0.1:2019, on by default inside the caddy container):

• on replaces Caddy’s routes with a single catch-all reverse_proxy to the maintenance container, keeping whatever listen addresses are already configured. Because it has no host or path matcher, it blankets every domain Caddy serves – LMS, CMS, and any host added by any other plugin – with no need to know their names, and takes effect instantly with no restart.

• off re-adapts apps/caddy/Caddyfile on disk and reloads that. The file on disk is always the source of truth, so there’s no separate state to keep in sync.

This only applies in tutor local (production-like) mode, since that’s where Caddy fronts the platform. tutor dev mode has no Caddy – each service is published on its own host port – so tutor maintenance on/off doesn’t apply there; the maintenance container is still started (see below) so you can preview the page directly.

Usage

tutor plugins enable maintenance
tutor images build maintenance
tutor images push maintenance
tutor local launch

Toggle maintenance mode:

tutor maintenance on

# ... perform maintenance ...

tutor maintenance off

Preview the maintenance page directly in tutor dev mode at http://localhost:8090 (published by the plugin’s dev docker-compose patch, chosen to avoid clashing with the other ports Tutor’s core and bundled plugins use in dev mode).

Configuration

tutor config save --set MAINTENANCE_PAGE_TITLE="We'll be back soon"
tutor images build maintenance
tutor local stop maintenance && tutor local start -d maintenance

The maintenance page’s templates live at tutormaintenance/templates/maintenance/build/maintenance/ – maintenance.html, and its stylesheet, favicon, and background image under assets/. After editing them (or any MAINTENANCE_PAGE_* setting), you must re-render, rebuild, and recreate the container for the change to take effect – a plain tutor local restart maintenance reuses the already-running container’s old image and won’t pick up the rebuild.
