caddy as a cors proxy #

To protect your API with CORS, our caddy ships with a CORS config. To enable it, see the snippet below.

The example scenario is as follows: Caddy proxies a container running your API on api.example.org, but you need the frontend on https://example.org/ to access it.

deploy:
  labels:
    caddy: api.example.org
    caddy.import: cors-origin http://example.org

To add multiple domains:

deploy:
  labels:
    caddy: api.example.org
    caddy.import_0: cors-origin http://example.org
    caddy.import_1: cors-origin http://another.example.org
