Simple reverse proxy for CORS issue.

```plain

... has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

* When you want to trust the resources of a other container

  * ex. minio, draw.io, piwigo etc ...

```shell

docker pull kaishuu0123/cors-reverse-proxy

docker run -it -d \

  -e CORS_REVERSE_PROXY_TARGET_URL=http://example.com \
