Vagrant is an open-source software product for building and maintaining portable virtual software development environments; e.g., for VirtualBox, KVM, Hyper-V, Docker containers, VMware, and AWS. It tries to simplify the software configuration management of virtualization in order to increase development productivity. Vagrant is written in the Ruby language, but its ecosystem supports development in a few other languages.

Vagrant commands

• vagrant up — Bring a box online.
• vagrant status — Show current box status.
• vagrant suspend — Pause the current box.
• vagrant resume — Resume the current box.
• vagrant halt — Shutdown the current box.
• vagrant destroy — Destroy the current box. By running this command, you will lose any data stored on the box.
• vagrant snapshot — Take a snapshot of the current box.

Examples

Rancher

The following is an example of bringing up Rancher (pre-v2.x):
