The `docker/php.ini` file is used to set some settings for PHP. It [looks like this](https://github.com/superfly/flyctl/blob/master/scanner/templates/laravel/common/docker/php.ini).

Update these:

```ini
post_max_size = 2M
upload_max_filesize = 0M
memory_limit = 128M

```

Based on your error message it sounds like it’s related to `memory_limit` specifically. Do you know how large the file is? Using streaming should, in theory, be efficient enough to not need a high PHP limit. But if you need to increase the memory limit, you can!

Don’t forget your Fly virtual machine has its own cap on memory usage ([default of 256m](https://fly.io/docs/about/pricing/) for the free tier).
