Users want to be able to override the request `max_size` to upload
larger files. But they will not be able to if the patch is placed after
the `request` directive. So we move the patch statement before the
directive. Also, we wrap the `request_body` directives within `handle`
statements. If not, then different sizes are not managed properly.
To override the max upload size in the cms, add the following to the
"caddyfile-cms" patch:
handle_path /import/* {
request_body {
max_size 500MB
}
}

Compressing assests would lead to readuce transfer size.
As testing with frontend-app-learning/Olive, the network traffic
before was about ~4MB, after this it became ~1MB.
This change was suggested by Google Lighthouse[1], there are of
course more suggestion but this was one the easiest and one of most
impactful.

Previously, we were redirecting all /*favicon.ico requests to the default
favicon. This meant that the favicon might not necessarily be correctly themed,
most notably in MFEs. Here, we resolve this issue by redirecting to the
theme-agnostic theming/asset/* url. Also, we restrict the overly generic regexp
for favicon url matching. We verified that we did not miss any url by running
the following command on the demo server:
tutor local logs caddy | grep --only-matching "host.*favicon.ico" | sort | uniq
When nginx was removed in favour of caddy, we decided that plugin
implementations of the "caddyfile" patch should make use of the "port" local
variable. However, local variables are not available from inside plugin
patches, which are rendered outside of the context of the parent templates.
For a more extensive description of the problem, see:
https://github.com/overhangio/tutor-mfe/pull/23#issuecomment-964016190
We still want to make it easy for developers to decide what should the port be
for caddy hosts. To do so, we make use of environment variables that are passed
at runtime to the caddy container.
Thus, a regular plugin patch should look like this:
{{ PLUGIN_HOST }}{$default_site_port} {
import proxy "myplugin:8000"
}
- 💥[Improvement] Upgrade Open edX to Koa
- 💥 Setting changes:
- The ``ACTIVATE_HTTPS`` setting was renamed to ``ENABLE_HTTPS``.
- Other ``ACTIVATE_*`` variables were all renamed to ``RUN_*``.
- The ``WEB_PROXY`` setting was removed and ``RUN_CADDY`` was added.
- The ``NGINX_HTTPS_PORT`` setting is deprecated.
- Architectural changes:
- Use Caddy as a web proxy for automated SSL/TLS certificate generation:
- Nginx no longer listens to port 443 for https traffic
- The Caddy configuration file comes with a new ``caddyfile`` patch for much simpler SSL/TLS management.
- Configuration files for web proxies are no longer provided.
- Kubernetes deployment no longer requires setting up a custom Ingress resource or custom manager.
- Gunicorn and Whitenoise are replaced by uwsgi: this increases boostrap performance and makes it no longer necessary to mount media folders in the Nginx container.
- Replace memcached and rabbitmq by redis.
- Additional features:
- Make it possible to disable all plugins at once with ``plugins disable all``.
- Add ``tutor k8s wait`` command to wait for a pod to become ready
- Faster, more reliable static assets with local memory caching
- Deprecation: proxy files for Apache and Nginx are no longer provided out of the box.
- Removed plugin `{{ patch (...) }}` statements:
- "https-create", "k8s-ingress-rules", "k8s-ingress-tls-hosts": these are no longer necessary. Instead, declare your app in the "caddyfile" patch.
- "local-docker-compose-nginx-volumes": this patch was primarily used to serve media assets. The recommended is now to serve assets with uwsgi.
