Form submission redirects to localhost:8080

I'm running Blazer using the Docker image on EC2 and accessing it via the Internet. Everything works great except form submission redirects to localhost:8080 (the default host Blazer is running on) instead of the URL in the browser.

I'm running Blazer behind nginx using the default command suggested in the README:

docker run -e DATABASE_URL=... -e BLAZER_USERNAME=... -e BLAZER_PASSWORD=... ankane/blazer:latest

I probably need to set the host somewhere, but it's not obvious from looking at the Blazer repo or this one where that config could be.

Figured it out. I just need to forward the Host header to Blazer from nginx:

location / {
    proxy_set_header Host            $host;
    proxy_set_header X-Forwarded-For $remote_addr;
    proxy_pass http://localhost:8080;
}
