Intro to vagrant
- 1. and STUFF
- 2. * Vagrant is a tool for creating, managing and distributing portable development environments.
- 3. * Wrapper around a variety of virtual machine providers. * Single command that uniformly creates, provisions, destroys, and connects to machines * Replicate and rebuild whole VM instantly
- 5. * Open source tool. * Works on Mac OS X, Windows and Linux
- 6. Zero to VM in Seconds * Vagrant up
- 7. Main Concepts ‘vagrant’ cliBoxes Vagrantfile
- 8. vagrant reads a Vagrantfile and builds a machine based on a template called box.
- 9. Boxes * Template from which machines are created. * Contains pre –installed OS * Boxes managed with vagrant command line
- 10. Boxes * Many publically available - http://www.vagrantbox.es/ - https://vagrantcloud.com/discover/featured - https://github.com/jedi4ever/veewee/tree/master/templates * Can be custom build - vagrant package --base <vm name> * Preinstalled with specific software - Veewee - Packer
- 11. Packer http://www.packer.io/ Created by Hashicorp Some functionality overlaps with Vagrant Useful with Vagrant some-os-distro.iso → distro.box
- 12. Packer templates h"ps://www.google.lt/search?q=packer+templates h"ps://github.com/monai/packer-‐templates
- 13. Vagrantfile * Per-project configuration file read by vagrant. * Describe machine properties, software to be provisioned, network, etc… * Simple Ruby based DSL
- 14. Vagrantfile example VAGRANTFILE_API_VERSION = "2" Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| config.vm.box = "MantasK/centos-‐6.5-‐x86_64-‐puppet" config.vm.host_name = 'test77v1.dev1.adform.com' config.vm.provider "virtualbox" do |vm| vm.customize [ "modifyvm", :id, "-‐-‐memory", "2048", "-‐-‐cpus", "2" ] end end
- 15. Vagrantfile cli • Manages entire lifecycle of the dev environments • $ vagrant …
- 16. Vagrantfile cli Vagrant up Vagrant ssh Vagrant destroy
- 17. Vagrantfile cli Vagrant init Vagrant box Vagrant suspend Vagrant halt Vagrant plugin Vagrant package https://docs.vagrantup.com/v2/cli/index.html
- 19. Providers A provider manages compute resources for virtual machines Allows to use the right provider for the different environment
- 20. Providers VAGRANTFILE_API_VERSION = "2" Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| config.vm.box = "MantasK/centos-‐6.5-‐x86_64-‐puppet" config.vm.host_name = 'test77v1.dev1.adform.com' config.vm.provider "virtualbox" do |vm| vm.customize [ "modifyvm", :id, "-‐-‐memory", "2048", "-‐-‐cpus", "2" ] end end
- 21. Providers $ vagrant box list $ vagrant box add <name> <url> $ vagrant up -‐-‐provider=<name>
- 22. Synced Folders Automaticaly syncs folders from host to guest Types: VirtualBox, Rsync, SMB, NFS, Etc., Default: Vagrant will share your project directory (the directory with the Vagrantfile) to /vagrant
- 23. Synced Folders VAGRANTFILE_API_VERSION = "2" Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| config.vm.box = "MantasK/centos-‐6.5-‐x86_64-‐puppet" config.vm.host_name = 'test77v1.dev1.adform.com’ config.vm.synced_folder "data", "/tutorial" config.vm.provider "virtualbox" do |vm| vm.customize [ "modifyvm", :id, "-‐-‐memory", "2048", "-‐-‐cpus", "2" ] end end
- 24. Networking Forwarded Ports - basically NAT Private Network - Host-only networking Public Network - Bridged Networking You can use mix and match – couple of those together or couple of one
- 25. Networking VAGRANTFILE_API_VERSION = "2" Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| config.vm.box = "MantasK/centos-‐6.5-‐x86_64-‐puppet" config.vm.host_name = 'test77v1.dev1.adform.com’ config.vm.synced_folder "data", "/tutorial” config.vm.network "forwarded_port", guest: 80, host: 8080 config.vm.network "private_network", ip: "172.16.0.11" config.vm.provider "virtualbox" do |vm| vm.customize [ "modifyvm", :id, "-‐-‐memory", "2048", "-‐-‐cpus", "2" ] end end
- 26. Provisioning Install required software as part of ‘vagrant up’ Supports: Shell, Ansible, Docker, Puppet, Salt
- 27. Provisioning Puppet apply VAGRANTFILE_API_VERSION = "2" Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| config.vm.box = "MantasK/centos-‐6.5-‐x86_64-‐puppet" config.vm.host_name = 'test77v1.dev1.adform.com’ … config.vm.provider "virtualbox" do |vm| … config.vm.provision "puppet" do |puppet| puppet.manifests_path = "puppet/manifests" puppet.module_path = "puppet/modules" puppet.manifest_file = "site.pp" end end
- 28. Provisioning Puppet agent VAGRANTFILE_API_VERSION = "2" Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| config.vm.box = "MantasK/centos-‐6.5-‐x86_64-‐puppet" config.vm.host_name = 'test77v1.dev1.adform.com’ … config.vm.provider "virtualbox" do |vm| … config.vm.provision "shell", inline: "sudo /usr/bin/puppet agent -‐-‐verbose –onekme –no-‐daemonize -‐-‐server puppetmaster.adform.com -‐-‐wailorcert 60 -‐-‐environment noenv" config.vm.provision "puppet_server" do |puppet| puppet.puppet_server = "puppetmaster.adform.com" puppet.opkons = ['-‐-‐test', '-‐-‐configkmeout 1200'] end end
- 29. Multi machine Manage multi-machine cluster with a single Vagrantfile Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| config.vm.define "node1" do |node1| node1.vm.box = "MantasK/centos-‐6.5-‐x86_64-‐puppet" node1.vm.host_name = 'node1.test.com' node1.vm.provider "virtualbox" do |vb| vb.customize ["modifyvm", :id, "-‐-‐memory", "2048"] end node1.vm.network "private_network", ip: "172.16.0.11" end config.vm.define "node2" do |node2| node2.vm.box = "MantasK/centos-‐6.5-‐x86_64-‐puppet" node2.vm.host_name = 'node2.test.com' node2.vm.provider "virtualbox" do |vb| vb.gui = true vb.customize ["modifyvm", :id, "-‐-‐memory", "1048"] end node2.vm.network "private_network", ip: "172.16.0.21" end end
- 30. Plugins Extensions. Lots of them! https://github.com/mitchellh/vagrant/wiki/Available-Vagrant-Plugins $ vagrant plugin install vagrant-‐aws $ vagrant up --provider=aws
- 34. Docker * Linux Only * Open Source * uses LinuX Containers (LXC) * run in the same operating system as its host. * uses AuFS for the file system
- 35. Docker vs VMs
- 36. Docker vs VMs Full Issolation Resources guaranteed Size: 1GB VM x # VMs Performance: overhead Minutes to start Need conversion Less Issolation No guaranteed resources Size: 1GB ( little over J) Performance: no overhead Seconds to start Portable
- 37. Docker portable
- 38. Docker vs VMs full isolation with guaranteed resources => VMs isolate processes from each other and want to run a ton of them => LXS
- 40. Docker Hello World $ docker run -‐d ubuntu:14.04 /bin/sh -‐c "while true; do echo hello world; sleep 1; done” $ docker ps $ docker logs <name>
- 41. Docker CLI $ docker run -‐d -‐P training/webapp python app.py
