Vagrant to the rescue

Many developers know the pain of setting up a development machine and share the setup with the team - Putting the same folders in the same place, keeping configurations in sync and managing external dependencies. Vagrant solves this problem by creating a development environment inside a virtual machine and making it easy to share with other developers. Within this talk, I'll take the audience on a trip from a time where everybody would install stuff on localhost until the software starts working to a land where the environment one develops in mirrors the production environment as closely as possible without changing the laptop/pc of the developer. I'll talk about devops and configuration management briefly and show how one can get started with vagrant. After this talk, the audience knows what problems vagrant solves and how to get started.

15. Basic workflow
    $ vagrant init Sgoettschkes/debian7-ansible
    $ vagrant up
    # box is booting
    $ vagrant ssh
    # It’s actually a normal, headless VM!
    $ exit

16. Basic workflow
    $ vim Vagrantfile
    # change config
    # add provisioners and so on
    $ git init
    $ git commit -Am ‘I am using Vagrant now!’
    # Keep the Vagrantfile and files needed for provisioning
    # in git (or any other scm) to share with others

17. Basic workflow
    $ git clone git@github.com:awesomecompany/awesomeVm.git
    $ cd awesomeVm && vagrant up
    # VM is setup the same as on your co-workers machine
    # You can now work on your project

18. Basic workflow
    # Co-worker updated Vagrantfile/provisioning files
    $ git pull --rebase
    $ vagrant provision
    # VM is up to date again

19. Basic workflow
    # You wanna change some Vagrant related stuff
    $ vim Vagrantfile
    # Change it!
    $ vim playbook.yml
    # Change something here as well, maybe?
    $ vagrant provision
    # Your box is up to date again
    $ git commit -am ‘Incredible changes’ && git push
