Vagrant is a virtualization technology that allows you to configure virtualization software such as Linux Containers and VirtualBox. It is commonly used together with orchestration tools like Ansible, and Chef.
To get started, download Vagrant here - https://www.vagrantup.com/downloads.html
Create a folder and run
vagrant init
This should create a VagrantFile.
Similar to Docker, Vagrant is dependent on base images. Let's begin by downloading an ubuntu box:
vagrant box add hashicorp/precise32
Open VagrantFile and edit the following:
config.vm.box = "hashicorp/precise32"
You can always find other boxes here:
https://atlas.hashicorp.com/boxes/search
Let's boot up the box:
vagrant up
vagrant ssh
You can check the status of the machine by running:
vagrant status
Do not delete the folder /vagrant, it's a synced folder
Let's begin by loading a script that will install apache.
In your hosts machine's root folder, create s file called bootstrap.sh
vi bootstrap.sh
Add the following:
apt-get update
apt-get install -y apache2
if ! [ -L /var/www ]; then
rm -rf /var/www
ln -fs /vagrant /var/www
fi
In VagrantFile, add
Vagrant.configure("2") do |config|
config.vm.box = "hashicorp/precise32"
config.vm.provision :shell, path: "bootstrap.sh"
end
Reload the provision:
vagrant reload --provision
Test the status of apache:
vagrant ssh
service apache2 status
Try running:
wget -qO- 127.0.0.1
Add the following line in VagrantFile for port forwarding, so we can see webpages from our host browsers
config.vm.network :forwarded_port, guest: 80, host: 4567
Run
vagrant reload
In your browser, do
http://127.0.0.1:4567
If you want to share this image to Altas to share/backup your files, register an account at
https://atlas.hashicorp.com/
Run
vagrant login
vagrant share
In the browser, access the url that's outputted by the terminal.
When you finished sharing, Ctrl = C to terminate it.
When you are done with your vagrant box, you can use the following:
vagrant suspend - state is saved, quick to start up, consumes space
vagrant halt - guest OS is shut down, consumes space
vagrant destroy - removes the guest machine
You can use vagrant up to start it again.
By default, the vagrant box is backed with Virtual Box.
But you can easily change it to VMware or AWS by:
vagrant up --provider-vmware_fusion
vagrant up --provider=aws
