Nginx Upload Module Chunked

nginx.conf

# See http://wiki.nginx.org/HttpUploadModule
location = /upload-restore-archive {

  # if resumable uploads are on, then the $upload_field_name variable
  # won't be set because the Content-Type isn't (and isn't allowed to be)
  # multipart/form-data, which is where the field name would normally be
  # defined, so this *must* correspond to the field name in the Rails view
  set $upload_field_name "archive";

  # location to forward to once the upload completes
  upload_pass /backups/archives/restore.json;

  # filesystem location where we store uploads
  #
  # The second argument is the level of "hashing" that nginx will perform
  # on the filenames before storing them to the filesystem. I can't find
  # any documentation online, so as an example, say we were using this
  # configuration:
  #
  #   upload_store /tmp/uploads 2 1;
  #
  # A file named '43829042' would be written to this path:
  #
  #   /tmp/uploads/42/0/43829042
  #
  # I hope that's clear enough. The argument is required and must be
  # greater than 0. You can see the implementation here:
  #
  #  http://lxr.evanmiller.org/http/source/core/ngx_file.c#L118
  upload_store /backup/upload 1;

  # whether uploads are resumable
  upload_resumable on;

  # access mode for storing uploads
  upload_store_access user:r;

  # maximum upload size (0 for unlimited)
  upload_max_file_size 0;

  # form fields to be passed to Rails
  upload_set_form_field $upload_field_name[filename] "$upload_file_name";
  upload_set_form_field $upload_field_name[path] "$upload_tmp_path";
  upload_set_form_field $upload_field_name[content_type] "$upload_content_type";
  upload_aggregate_form_field $upload_field_name[size] "$upload_file_size";

  # hashes are not supported for resumable uploads
  # https://github.com/vkholodkov/nginx-upload-module/issues/12
  #upload_aggregate_form_field $upload_field_name[signature] "$upload_file_sha1";
