OpenSlides Proxy

The proxy is the entrypoint for traffic going into an OpenSlides instance and hides all the services needed for production behind a single port. On the docker container this will be port 8000. An arbitrary port from the host can then be forwarded to that (e.g. 443->8000).

HTTPS

It is possible to make use of caddy's automatic https feature in order to not having to manually generate TLS certificates. Set ENABLE_AUTO_HTTPS=1 and EXTERNAL_ADDRESS=openslides.example.com to activate it. Caddy will then retrieve a letsencrypt certificate for that domain. For testing a setup e.g. ACME_ENDPOINT=https://acme-staging-v02.api.letsencrypt.org/directory can also be set to avoid hitting rate limits. Importantly, port 80 on the host must be forwarded to port 8001 on which caddy will answer the ACME-challenge during certificate retrieval.

Alternatively a locally generated certificate can be used by setting ENABLE_LOCAL_HTTPS=1 HTTPS_CERT_FILE=path/to/crt HTTPS_CERT_FILE=path/to/key and providing cert and key files at the specified location. This is mostly for dev and testing setups and is not useful for a public domain as the cert is not issued by a trusted CA and therefore not trusted by browsers. If set, this overrules ENABLE_AUTO_HTTPS.
