 A `docker-compose.varnish_extras.yaml` file is generated on install which replaces the `VIRTUAL_HOST` variable of the web container with a sub-domain of the website URL. For example, `mysite.ddev.site`, would be accessible via Varnish on `mysite.ddev.site` and directly on `novarnish.mysite.ddev.site`.

You can also use `ddev create-novarnish-hosts` which will call the `ddev hostname` command for all domains without a `novarnish.*` host entry.
