### **eucadev** ➠ _tools for Eucalyptus developers and
testers_
These tools allow one to deploy a Eucalyptus cloud—in a
Vagrant-provisioned VM or in a cloud instance from AWS or
Eucalyptus—with minimal effort. Currently, only single-node
installations in virtual resources are supported, but we have
plans to support multiple nodes, bare-metal provisioining,
and more.

### Dev/test environment in a VirtualBox VM
This method produces a dev/test environment in a single virtual machine, with all
Eucalyptus components deployed in it. By default, components will be built from latest
source, which can be modified and immediately tested on the VM. The source will be
located on a 'synced folder' (`eucalyptus-src`), which can be edited on the host system
but built on the guest system. Alternatively, you can install from latest packages, saving
time.
1. Install [VirtualBox](https://www.virtualbox.org)
2. Install [Vagrant](http://www.vagrantup.com/) >= 1.5.2
3. Install [git](http://git-scm.com)
4. Install [ChefDK](https://downloads.chef.io/chef-dk/)
5. Install vagrant plugins
$ vagrant plugin install vagrant-berkshelf --plugin-version '>= 2.0.1'
$ vagrant plugin install vagrant-omnibus

21. eucadev.mdを見てみる（3）
6. Check out [eucadev](https://github.com/eucalyptus/eucalyptus-cookbook/
eucadev.md) (ideally [fork](http://help.github.com/fork-a-repo/) it and clone the fork to
your local machine, so you can contribute):
$ git clone https://github.com/eucalyptus/eucalyptus-cookbook.git
7. *Optionally:* Check the default parameters in `eucadev/Vagrantfile` and `eucadev/
roles/cloud-in-a-box.json`
* `install-type` is `"source"` by default. Set the value to `"packages"` for an RPM-based
installation, which can take less than half the time of a source install (e.g., 20 min
instead of 48), but won't allow you to edit and re-deploy code easily.
* In Vagrantfile, `memory` is 3GB (`3072`) by default. For a source-based install without
a Web console, you may be able to get away with less, such as 1GB. Giving the VM
more should improve performance.
8. Start the VM and wait for eucadev to install Eucalyptus in it (may take a long time,
_20-60 min_ or more):
$ cd eucadev; vagrant up

22. なんかこの手順でやってみると
できるかもしれない
