Use OpenStack as a Vagrant Provider

Vagrant is a very popular tool within developer communities. It makes easy to manage virtual machines and is very useful to set up development or staging environments. Vagrant can be plugged on various VM providers using its plug-in mechanism, VirtualBox, Docker, AWS... In this talk we will present the open source project Vagrant Openstack Provider, implementing a plug-in to use Openstack as a cloud provider for Vagrant. We will present how to use it, the key features, some interesting use cases and the roadmap for future releases.

1. Use OpenStack as a Vagrant Provider
2. Julien Vey Numergy @julienvey Guillaume Giamarchi Numergy @ggiamarchi
3. Vagrant : Development environments made easy
4. Repeatable Build and destroy environments in a second Configurable Describe all the steps to build an environment in a single file Easy to use Simple command line client to manage environments
5. STEP 1 Describe your environment
6. Vagrant.configure('2') do |config| config.vm.box = 'base' config.vm.provision 'shell', inline: 'apt-get install -y git' end Vagrantfile
7. STEP 2 Start it!
8. $ vagrant up
9. That’s all you need to get started
10. Vagrant manages Virtual Instances
11. not created active shutdown suspended up suspend halt up up resume destroy But also… $ vagrant ssh $ vagrant status $ vagrant provision
12. Vagrant uses Providers (default is VirtualBox)
13. Built-in Providers
14. VirtualBox VMWare (charged) Docker Hyper-V
15. $ vagrant up VirtualBox VM on your local machine
16. $ vagrant up 1 x 1 x VirtualBox VM on your local machine
17. $ vagrant up VirtualBox VM on your local machine n x n x
18. Local resources are LIMITED
19. We need More resources
20. Cloud resources are (virtually) UNLIMITED
21. Vagrant works with Plugins
22. Some plugins… Provision vagrant-berkshelf, vagrant-puppet-install, vagrant-fabric… Local Domain Resolution vagrant-dns, vagrant-hostmanager… Testing vagrant-cucumber, vagrant-serverspec…
23. Custom Providers
24. vagrant-aws vagrant-azure vagrant-digitalocean vagrant-kvm vagrant-lxc … and many more
25. Vagrant OpenStack Provider github.com/ggiamarchi/vagrant-openstack-provider
26. Why an OpenStack provider ?
27. Scale As many instances as your quotas allow Share Created instances can be shared with team members
28. Vagrant OpenStack Provider Quick Start
29. Vagrant.configure('2') do |config| config.ssh.username = 'stack' config.vm.provider :openstack do |os| os.openstack_auth_url = 'http://keystone-server.net/v2.0/tokens' os.username = 'openstackUser' os.password = 'openstackPassword' os.tenant_name = 'myTenant' os.flavor = 'm1.small' os.image = 'ubuntu' os.floating_ip_pool = 'publicNetwork' end end
30. $ vagrant up --provider=openstack
31. Keystone Authenticate & Resolve Catalog Resolve Image Resolve Flavor Resolve Floating IP Create Instance Assign Floating IP Nova
32. some features will require other openstack services
33. Supported features up/halt suspend/resume ssh reload provision
34. Specific features SSH key generation Floating IPs Networks Volumes Custom commands
35. SSH Key generation
36. SSH Key Generation How it works $ vagrant up generate ssh keypair upload public key to nova launch instance with generated keypair store private key locally
37. SSH Key Generation How it works $ vagrant ssh use private key generated previously
38. SSH Key Generation How it works Keys are generated in .vagrant/machines/<machine_name>/openstack/ With name vagrant-generated-<hash> Easy to debug ssh connection with ssh -i .vagrant/… user@machine
39. SSH key configuration is no longer needed
40. Floating IP allocation
41. Floating IP allocation Directly assign already allocated floating IP config.vm.provider :openstack do |os| os.floating_ip = '80.81.82.83' end
42. Floating IP allocation Use available IP from a pool or allocate a new one config.vm.provider :openstack do |os| os.floating_ip_pool = 'PublicNetwork' end
43. Assign Networks
44. Assign networks Attach networks by name, by id,with fixed IP address… config.vm.provider :openstack do |os| os.networks = [ 'net-name-01', '287132f0-57e6-4c31-a1ee-4823e9786ff2', { name: 'net-name-03', address: '192.168.22.43' } ] end
45. Attach Volumes
46. Attach Volumes Attach volumes by name, by id, with device… config.vm.provider :openstack do |os| os.volumes = [ '619e027c-f4a9-493d-8c15-c89de81cb949', 'vol-name-02', { id: '410096ff-ef71-4ca4-8006-e5bd9e99239a', device: '/dev/vdc' }, { name: 'vol-name-04', device: '/dev/vde' } ] end
47. Boot from Volume
48. Boot from Volume config.vm.provider :openstack do |os| os.volume_boot = '619e027c-f4a9-493d-8c15-c89de81cb949' end
49. Custom Commands
50. Custom commands OpenStack specific commands in vagrant $ vagrant openstack Usage: vagrant openstack command Available subcommands: image-list List available images flavor-list List available flavors network-list List private networks in project floatingip-list List floating IP and floating IP pools volume-list List existing volumes
