Vagrant is being ported to Go to maintain its Ruby-based features while supporting new development workflows and ecosystems, including a client-server architecture that allows for secure actions on remote hosts and sharing of configuration resources among team members. The changes will also improve security by enabling a privileged service to execute known and trusted commands without direct user interaction, and offer better global configuration management through a server-based approach. Additionally, Vagrant 3.0 will introduce a new plugin API with the help of the HashiCorp go-plugin library, allowing for cross-platform compatibility and easier distribution of plugins. The porting process aims to be seamless, with two minor releases and one major release planned, starting from Vagrant 2.3, which will include an initial alpha version of the Go-based implementation, followed by Vagrant 2.4, which will feature a new Go implementation as the primary executable, and finally Vagrant 3.0, which will only support plugins using the new API and HCL-based Vagrantfiles.
