====== Premiers Pas avec Vagrant ======


===== Avant-propos =====


===== Vagrant - Installation =====

  * voir également ici : https://j.hommet.net/initiation-vagrant/
===== Vagrant - - Utilisation de base =====

Toutes les actions se réfèrent à la machine (**box**) décrite dans la **Vagrantfile** 

Ici, une **Vagrantfile** permettant d'installer **docker** sur une vM debian/bullseye 64

Vagrant.configure("2") do |config|
  # The most common configuration options are documented and commented below.
  # For a complete reference, please see the online documentation at

  # Every Vagrant development environment requires a box. You can search for
  # boxes at https://vagrantcloud.com/search.
  config.vm.box = "debian/bullseye64"
  config.vm.hostname = "docker"

  # Disable automatic box update checking. If you disable this, then
  # boxes will only be checked for updates when the user runs
  # `vagrant box outdated`. This is not recommended.
  # config.vm.box_check_update = false

  # Create a forwarded port mapping which allows access to a specific port
  # within the machine from a port on the host machine. In the example below,
  # accessing "localhost:8080" will access port 80 on the guest machine.
  # NOTE: This will enable public access to the opened port
  # config.vm.network "forwarded_port", guest: 80, host: 8080

  # Create a forwarded port mapping which allows access to a specific port
  # within the machine from a port on the host machine and only allow access
  # via 127.0.0.1 to disable public access
  # config.vm.network "forwarded_port", guest: 80, host: 8080, host_ip: "127.0.0.1"

  # Create a private network, which allows host-only access to the machine
  # using a specific IP.
  # config.vm.network "private_network", ip: "192.168.33.10"

  # Create a public network, which generally matched to bridged network.
  # Bridged networks make the machine appear as another physical device on
  # your network.
  config.vm.network "public_network"

  # Provider-specific configuration so you can fine-tune various
  # backing providers for Vagrant. These expose provider-specific options.
  # Example for VirtualBox:
  #
   config.vm.provider "virtualbox" do |vb|
  #   # Display the VirtualBox GUI when booting the machine
  #   vb.gui = true
  #
  #   # Customize the amount of memory on the VM:
     vb.memory = "3096"
   end
  #
  # View the documentation for the provider you are using for more
  # information on available options.

  # Enable provisioning with a shell script. Additional provisioners such as
  # Ansible, Chef, Docker, Puppet and Salt are also available. Please see the
  # documentation for more information about their specific syntax and use.
   config.vm.provision "shell", inline: <<-SHELL
     apt-get update
     apt install -y wget curl git vim
     if ! which docker ; then
       curl -s -o getdocker.sh https://get.docker.com

==== Création du projet Vagrant ====

<code bash>
mkdir vgtest
cd vgtest
vagrant init debian/bullseye64
</code>

On peut alors éditer le fichier **Vagrantfile** pour adapter aux condition locales :

==== Lancer le projet Vagrant ====

<code bash>
mkdir vgtest
cd vgtest
vagrant up 
Bringing machine 'default' up with 'virtualbox' provider...

==> default: Matching MAC address for NAT networking...
==> default: Checking if box 'debian/bullseye64' version '11.20220912.1' is up to date...
==> default: Setting the name of the VM: gitweb_default_1666296870962_77305
==> default: Clearing any previously set network interfaces...
==> default: Available bridged network interfaces:
1) wlp1s0
2) enp2s0

==> default: Checking for guest additions in VM...
    default: The guest additions on this VM do not match the installed version of
    default: VirtualBox! In most cases this is fine, but in rare cases it can
    default: prevent things such as shared folders from working properly. If you see
    default: shared folder errors, please make sure the guest additions within the
    default: virtual machine match the version of VirtualBox you have installed on
    default: your host and reload your VM.
