HAProxy was replaced by Caddy, so obviously variables should not longer
carry HAPROXY in their names to avoid confusion.
To hopefully make future changes less likely to break configurations,
we'll keep variable and image names generic (proxy instead of caddy).
- Removing channels. Going back to a wsgi deployment
- Removed server projector code
- Autoupdate throttling is now in the client
- New communication stack in the client
- Adopted all deployment methods: Docker stack and docker compose (prod and dev)
- Added autoupdate service as submodule
This setup chooses to avoid the env_file option available for Docker
Compose files. Docker has a peculiar way of parsing variables which
makes it, for example, include quotes verbatim.
This is both confusing and incompatible with shells parsing the same
file which is a requirement. For this reason, the configuration does
not import the complete environment using env_file but assigns variables
explicitly on a need-to-know basis in the YAML file, much like Docker
secrets.
Since the configuration is generated automatically, the burden on users
is the same as with env_file: they only need to edit .env for
customizations.
