CORS in Api proxy with caddy and docker

Caddy CORS

Use a caddy docker container to proxify an API and configure CORS.

Example

The example consists of two services, an API and a client. The API responses the path and the query string of the URL used in the incoming GET requests. The client makes a GET request to the API and renders the response in the web browser.

Usage

To run the services it is only needed to execute

docker-compose up

To test the API just try in your browser http://api-proxy.container.address/sample/path?q=uery&s=tring.

To test the client, open http://client-proxy.container.address.

If you use docker-hoster, you can access the API through http://api.caddy-cors.com and the client through http://client.caddy-cors.com.

Note

I defend personally the idea of solving this problem only once, on the web server. The use of CORS extensions in web frameworks is only a temporary solution for development. So, why not always use docker, even in development?
