Vagrant

Providers #

Trellis supports most of Vagrant's common providers automatically. By default we recommend VirtualBox since it's free and open source. However, if you need or prefer one of the commercial providers (eg: VMWare or Parallels), they can be used as well.

This main exception here is for developers on Macs with Apple Silicon chips. Because these are ARM-based CPUs, VirtualBox won't work; it's limited to x86 CPUs like Intel and AMD.

Parallels (Apple Silicon Macs) #

Currently Parallels is the best solution for running virtual machines on Apple Silicon based Macs. Unfortunately, Parallels is a paid and commercial product unlike VirtualBox. Parallels Pro is required as well which has a yearly subscription price of $99 USD.

Installation:

1. Purchase Parallels Pro
2. Install Parallels
3. Install the Vagrant provider: vagrant plugin install vagrant-parallels

See the Parallels site for more details.

Configuration #

Editing the Vagrantfile directly should be avoided unless necessary. Instead, you can easily set common settings in vagrant.default.yml.

To make local overrides, create a vagrant.local.yml file with any overrides you want. Note: this file is Git ignored.

Vagrantfile #

The example Vagrantfile in this project can be kept in this folder or moved anywhere else such as a project/site folder. Generally, if you want to have multiple sites on 1 Vagrant VM, you should keep the Vagrantfile where it is (in the trellis dir). If you want to have 1 Vagrant VM per project/site, you should make copies of the Vagrantfile and put them into each project's dir. You'd then run vagrant up from the project-specific directory.

Synced folders #

Trellis uses Vagrant's synced folder feature to sync folders from your local machine (like your Trellis project itself) to the virtual machine. Vagrant supports different types of mount options for synced folders like NFS, SMB, and Virtualbox's native option.

By default, Trellis tries to default to NFS because it offers the best performance for macOS users. To change the mount type for synced folders, you can change the vagrant_mount_type configuration option:

vagrant_mount_type: nfs

Whenever you change the mount type on an existing Vagrant box, you need to run vagrant reload for the changes to take affect (or destroy and create a new one).

We suggest trying differet options and seeing what works best for you.

NFS #

For more NFS details and troubleshooting, see the official Vagrant docs.

Virtualbox #

While nfs is the default mount type, the virtualbox method might offer better I/O performance on Linux hosts (up to 9x faster writes and 25x faster reads). virtualbox is also much simpler than nfs since it's built-into VirtualBox and requires no other software or configuration.

See this issue for details and tests results.
