The document discusses Vagrant, a tool for managing virtualized development environments, detailing its features like configuration, reproduction, and sharing. It includes practical commands for using Vagrant and provides examples of Vagrantfile configurations for server provisioning with tools like Chef and Salt. The presentation emphasizes the importance of reusability in environments and shares links for further references.

2. Don’t sleep developer!

3. Decrease the complexity
•Start up project
•Flexibility

4. What isVagrant?
•Provider
•Provisioning
•Networking
•Share Folder

5. WhyVagrant?
Vagrant allow to:
•Configure
•Reproduce
•Share
it’s very easy!

6. Command line
•$. vagrant box
•$. vagrant init
•$. vagrant up
•$. vagrant ssh
•$. vagrant destroy
•$. vagrant reload
•$. vagrant provision

7. Plugin
$. vagrant plugin install <name>
$. vagrant plugin remove <name>
$. vagrant plugin list

8. Vagrantfile - Configuration
# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.configure(“2”) do |config|
config.vm.define :web do |web|
web.vm.box = "precise64"
web.vm.box_url = "http://files.vagrantup.com/precise64.box"

9. Vagrantfile - Configuration
web.vm.network :private_network, ip: “192.168.33.222”
web.vm.network “port_forwarding”, guest: 80, host: 8080
config.vm.hostname = "cwitter-dev.local”
web.vm.synced_folder "../", "/var/www/cwitter", owner: "www-
data", group: "www-data"

10. Vagrantfile - Configuration
config.vm.provision :chef_solo do |chef|
chef.cookbooks_path = ["cookbooks"]
chef.add_recipe "apt"
chef.add_recipe "vim"
chef.add_recipe "openssl"
chef.add_recipe "apache2"
chef.add_recipe "postgresql::server”
end

11. Vagrantfile - Configuration
web.vm.provider :virtualbox do |v|
v.customize ["modifyvm", :id, "--memory", 512, "--name",
"cwitter-dev.local"]
end

12. PROVISIONING

13. How is it?
Server provisioning is a set of
actions to prepare a server with
appropriate systems, data and
software, and make it ready for
network operation

ning#Server_provisioning

14. I use one of this systems in production
•Updating
•Maintainability
•Scalibility

15. RISKS
Bug in your configurations
Price of good cookbook (Chef), formula (salt)…

16. Answer to this problem is…

17. REUSABILITY

18. Environments
•Production
•Develop
•Certification
•…

19. Vagrant configuration is shareable

20. VAGRANT AND SALT

21. Repository

22. Repository/prod/salt

23. Repository/dev/salt

24. Salt Provioning
Vagrant.configure("2") do |config|
config.vm.box = "precise64”
config.vm.hostname = “cwitter-dev.local”
web.vm.network “port_forwarding”, guest: 80, host: 8080
web.vm.synced_folder “.”, “/srv/”
web.vm.synced_folder “../”, “/var/www/cwitter”
config.vm.provision :salt do |salt|
salt.verbose = true
salt.minion_config = “./minion"
salt.run_highstate = true
salt.install_type = “daily”
end
end

25. Minion – Conf(1)
master: localhost
file_client: local

26. Minion – Conf(2)
file_roots:
base:
- /srv/base/salt
prod:
- /srv/prod/salt
dev:
- /srv/prod/salt
- /srv/dev/salt

27. Minion – Conf(3)
pillar_roots:

prod:

28. top.sls
