the proxy responds with a 421, if a host header with an invalid host
name is encountered. If nothing is provided (see default .env) all hosts
are allowed. Examples:
ALLOWED_HOSTS="localhost:8000 127.0.0.1:8000"
ALLOWED_HOSTS="some.domain.example.com"
Add EXTERNAL_HTTPS_PORT. See .env for the configuration.
For a subset of the images required by a Compose or Swarm Setup,
non-default names can be configured in .env. Originally, the names were
treated as the images' complete names, i.e., including an optional
registry domain. Using this setup, it was possible to pull the
irregularly updated auxiliary images from a default registry while, at
the same time, obtaining certain images from different registries.
Commit e225a57f97 changed this behavior. Since then, the names in .env
can only be used to change part of the image name, excluding the
registry. If a default registry is configured it is always prepended to
the given image name, breaking the original use case.
This patch removes the ability to override image names in .env.
Instead, the registry of each image can be customized.
The reasoning here is that the only common reason to change an image
name is to change its Docker registry. For example, while the default
registry may be set to default.example.com, it may be necessary to
obtain the backend image private.example.com/openslides-server. With
this patch, that would be achieved by the following configuration in
.env:
DOCKER_OPENSLIDES_BACKEND_REGISTRY="private.example.com"
For special cases, for which the images' basename must indeed be changed
as well, the template would need to be customized.
The templates are not backwards-compatible.
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.
