Vagga in VirtualBox

Status:	PoC

This is a prototype which brings vagga as the first-class tool to OS X and (possibly) windows using virtualbox

Installation

First download and install virtualbox. The project is tested on VirtualBox 5.1 but may work on earlier versions too.

Then run the following commands (assuming you have brew installed):

$ brew install python3 unison wget
$ pip3 install git+http://github.com/tailhook/vagga-box
[ .. snip .. ]
$ vagga
Available commands:
    run

Effectively it requires python >= 3.5 and unison 2.48.4 (unison is very picky on version numbers)

IDE support is enabled by the following command (and requires sudo access):

$ vagga _box mount
Running sudo mount -t nfs -o vers=4,resvport,port=7049 127.0.0.1:/vagga /Users/myuser/.vagga/remote
Password:
Now you can add ~/.vagga/remote/<project-name>/.vagga/<container-name>/dir
to the search paths of your IDE

You need to run it each time your machine is rebooted, or if you restarted your virtualbox manually.

Upgrading

Once you have installed vagga-box you can upgrade vagga inside the container using the following command-line:

vagga _box upgrade_vagga

Changing the disk size

By default, the disk size in Virtualbox is set to 20 GB. If necessary, it can be increased by the following steps:

1. Change VM's image size:

   $ vagga _box down
   $ VBoxManage modifyhd ~/.vagga/vm/storage.vdi --resize 40860
   $ vagga _box up
   

2. Change partition size inside VM:

   $ vagga _box ssh
   $ sudo apk add cfdisk e2fsprogs-extra
   $ sudo cfdisk /dev/sdb
       [ .. Delete /dev/sdb1 ..]
       [ .. New partition / default size / Primary .. ]
       [ .. Write changes / Quit .. ]
   $ sudo reboot
   

3. Final steps:

   $ vagga _box ssh
   $ sudo resize2fs /dev/sdb1
   $ sudo df -h  # Check size
   

Short FAQ

Why is it in python? For a quick prototype. It will be integrated into vagga as soon as is proven to be useful. Or may be we leave it in python if it would be easier to install.

So should I try this version or wait it integrated in vagga? Definitely you should try. The integrated version will work the same.

Is there any difference between this and vagga on linux? There are two key differences:

• you need to export ports that you want to be accessible from the host system
• we keep all the container files (and a copy of the project) in the virtualbox
• to view it from the host system mount nfs volume (vagga _box mount)
• to make filesync fast you can add some dirs to the ignore list (_ignore-dirs setting)

_ignore-dirs:
- .git
- tmp
- data

containers:
  django:
    setup:
    - !Alpine v3.3
    - !Py3Install ['Django >=1.9,<1.10']

commands:
  run: !Command
    description: Start the django development server
    container: django
    _expose-ports: [8080]
    run: python3 manage.py runserver

Please report if you find any other differences using the tool. Ah, but exact text of some error messages may differ, don't be too picky :)

Why `_expose-ports` are underscored? This is a standard way to add extension metadata or user-defined things in vagga.yaml. We will remove the underscore as soon as integrate it into main code. Fixing underscores isn't going to be a big deal.

Will linux users add `_expose-ports` for me? Frankly, currently probably now. But it's small change that probably no one will need to delete. In the future we want to apply seccomp filters to allow to bind only exposed ports on linux too.

What will be changed when we integrate this into vagga? We will move more operations from virtualbox into host system. For example list of commands will be executed by mac os. Also vagga _list, some parts of vagga _clean and so on. But we will do our best to keep semantics exactly the same.
