Vagrant – uruchom środowisko wirtualne w kilka minut

Obecnie możliwość szybkiego uruchomienia maszyny wirtualnej na dowolnym urządzeniu jest bardzo ważna nie tylko dla developerów tworzących oprogramowanie i potrzebujących środowisko wirtualne do testów, ale i inżynierów systemowych czy administratorów sieciowych. By ułatwić proces przenoszenia i instalowania maszyn wirtualnych, powstał projekt Vagrant.

Rozpoczęcie pracy z Vagrant zabiera kilka minut. By uruchomić maszynę wirtualną z Ubuntu należy wykonać kilka kroków:

bash-3.2$  vagrant init hashicorp/precise64
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.
  • po wykonaniu polecania w katalogu został utworzony nowy plik Vagrantfile:
bash-3.2$ ls -al

-rw-r--r--   1 seba  staff  3031  8 maj 13:14 Vagrantfile
bash-3.2$ less Vagrantfile 
  • uruchomić nową maszynę wirtualną:
