How to set permissions in vagrant through shared folders?

Question

ubuntu

I launched vagrant, put the site with the openCart installation into the shared folder on the host, open it, and the site writes that there are no rights to the directory/files - "Warning: Upload directory needs to be writable for OpenCart to work!"

Here is the vagrant config:

Vagrant.configure("2") do |config|

  config.vm.synced_folder "/Users/artemerbulatov/vagr-2/example2", "/var/www", owner: "root", group: "root"


  config.nfs.map_uid = Process.uid
  config.nfs.map_gid = Process.gid

  config.nfs.map_uid = 501
  config.nfs.map_gid = 20


  config.vm.box = "bento/ubuntu-18.04"
  config.vm.network "forwarded_port", guest: 80, host: 8080
  config.vm.provider "virtualbox" do |vb|
    vb.memory = "4096"
  end
  config.vm.provision "shell", inline: <<-SHELL
    sudo apt-get update
    sudo apt-get install -y nginx
  SHELL
end

Answer 1

I think that here
owner: "root", group: "root"
you need to use the user under which nginx runs - www-data.
