Dockerized cors proxy using nginx.

Meant for local development.

Proxy port is 1337, if you don't like that, replace it using search & replace across this codebase.

Whenever you call http://localhost:1337, the call will get proxied to http://${CORS_TARGET}:${CORS_TARGET_PORT}

Run using docker compose:

• Change ENV variables inside docker-compose.yml
• Run docker compose up -d

Run without docker compose:

docker run \
  --name corsproxy \
  --hostname corsproxy \
  --restart no \
  --network bridge \
  -p 1337:80 \
  -e NGINX_PORT=80 \
  -e CORS_TARGET=host.docker.internal \
  -e CORS_TARGET_PORT=8080 \
  -v "$(pwd)/default.conf.template:/etc/nginx/templates/default.conf.template:ro" \
  --add-host host.docker.internal:host-gateway \
  nginx:1.27-alpine \
  nginx-debug -g "daemon off;"

Notes

• Right now the proxy is pinned to nginx:1.27-alpine because it works as expected. If you'd like to experiment, feel free to bump it up. I occasionally bump the version and fix potentional issues.
