- 40. no share
- 41. native share - slow - os indipendent-ish
- 42. nfs - fast - win support :-(
- 43. rsync - no real share - update
- 44. VM Performance
- 47. Virtualbox 22 min VmWare 15 min
- 48. Virtualbox 22 min VmWare 15 min +30%
- 49. use VmWare if you can (it will cost you a few $)
- 50. use nfs if you can*
- 51. vagrant plugin install vbguest keeps guest addition updated
- 52. unless Vagrant.has_plugin?(“vagrant-vbguest") raise ”please install vagrant-vbguest” end
- 53. On VM I/O is the bottleneck
- 54. loading webpages running testsuites are READ heavy
- 55. move I/O outside shared folders
- 56. Default provider: virtualbox 3 PHP test suites with unit, functional, integration mix small (sf1): build runs in ~25 sec medium (zf2): build runs in ~2 mins large (sf2): build runs ~ 20 mins

- 75. Use host ssh keys
- 77. ForwardAgent yes check ssh config file in your host machine

- 80. Provisioning
- 81. to phansible or not to phansible?
- 82. quick and easy way to start they’re general old platforms are not supported a lot of a good ideas you can steal from
- 83. if which('ansible-playbook') config.vm.provision "ansible" do |ansible| ansible.playbook = "ansible/playbook.yml" ansible.inventory_path = "ansible/inventories/dev" ansible.limit = 'all' ansible.extra_vars = { private_interface: "192.168.33.99", hostname: "default" } end else config.vm.provision :shell, path: "ansible/windows.sh", args: ["default"] end
- 84. can you assume everyone in your team have the same version?
- 85. if which('ansible-playbook') config.vm.provision "ansible" do |ansible| ansible.playbook = "ansible/playbook.yml" ansible.inventory_path = "ansible/inventories/dev" ansible.limit = 'all' ansible.extra_vars = { private_interface: "192.168.33.99", hostname: "default" } end else config.vm.provision :shell, path: "ansible/windows.sh", args: ["default"] end
- 86. the provisioning tool is a moving part: wanna update? be careful
- 88. config.vm.provision :shell, :path => "scripts/bootstrap.sh", :args => "/var/www" config.vm.provision :shell, :path => “scripts/provision.sh", :args => "/var/www"
- 89. create your own template https://github.com/ideatosrl/vagrant-php-template
- 90. you’re in control of provisioning command you can perform additional checks on host machine
- 91. Distributing VMs
- 92. provisioning does not create immutable vm by default eg: package update on LTS
- 93. live on the edge and fix provision script use stable package repositories
- 94. https://speakerdeck.com/mitchellh/vagrant-usage-patterns Create and distribute your own VM
- 95. Golden image
- 96. vagrant package - -name mybox.box publish it somewhere (http, atlas) c.vm.box_url = “http://../mybox.box”
- 97. - Don’t make assumptions about the host - Provision first, then bake your own image - The more moving part the harder will get
- 98. Keep it simple
- 99. Thank you! _orso_ micheleorselli / ideatosrl [email protected]
