What is Vagrant?
feature
What is Vagrant? CUI software for virtualization software such as Virtualbox software that operates virtualization software such as Virtualbox virtualization software such as Virtualbox.
Although VirtualBox alone can build a Linux environment with GUI, managing it with CUI has the following advantages.
- Can be built with a single command
- Can automate construction
- Setting information can be shared.
Usage Procedure
install
The configuration for building a virtual machine is entered in a configuration file called vagrantfile in the Ruby language.
The specification is to read the vagrantfile by executing the vagrant up command.
Create a folder to run Vagrant and move it there
mkdir /user/vagrant
cd
Add a Box file
A *Box is an OS image file. It is a template for a virtual machine.
Boxes can be found at the following sites and others.
Example sentence:.
vagrant box add {BOXNAME} {URL}
vagrant box add CentOS7-test https://github.com/tommy-muehle/puppet-vagrant-boxes/releases/download/1.1.0/centos-7.0-x86_64.box
md Centos7-test
To install the BOX from the following URL
https://app.vagrantup.com/centos/boxes/7
$ vagrant box add centos/7
==> box: Loading metadata for box 'centos/7'
box: URL: https://vagrantcloud.com/centos/7
This box can work with multiple providers! The providers that it
can work with are listed below. Please review the list and choose
the provider you will be working with.
Confirmation of installed Box
vagrant box list
When you add a box, the following folders are created.
Box images such as centos are stored under the box folder.
C:\Users\{UserName}\.vagrant.d
PS C:\Users\d-wat\.vagrant.d> ls
Directory: C:\Users\{UserName}\.vagrant.d

Create a folder for each virtual machine
Create a directory for each virtual machine and a configuration file (Vagrantfile) in it for easy management.
$ cd ~/vagrant/ $ mkdir centos7 $ cd centos7/
Virtual machine initialization
The initialization process creates a vagrantfile.
vagrant box list
vagrant init Box name
vagrant init c entos/7
One Vagrantfile file is created in the folder where the * command is executed.
If you only use vagrant init, the Vagrantfile file will be created with "config.vm.box="base" instead of "config.vm.box="centos/7".
Running centos7 on VirtualBox
vagrant up
*VurtualBox manager will start CentOS7.
User：vagrant
Pass: vagrant
Switch to root with sudo
For ssh login directly from the terminal
vagrant ssh
Shut down CentOS7
vagrant halt
Virtual Machine Deletion
vagrant destroy
*CentOS7 is erased from the VurtualBox manager.
*Vagrantfile is not erased.
Check Box
vagrant box list
Delete Box
vagrant box remove BOX name
Check the version of VAGRANT
vagrant version
Vagrantfile configuration memo
Specify the name of VirtualBox
config.vm.provider "virtualbox" do |vb|
vb.name = "centos7"
end
Error messages in the vagrant command
The version of powershell currently installed on this host is less than the required minimum version. Please upgrade the installed version of powershell to the minimum required version and run the command again.
It means that the version of PowerShell is old, so it needs to be upgraded.
It seems to be a bug in ComEmu. If I launch the standard PowerShell terminal and type the command, there is no error.
