Usage Scenario

We build a friendly environment for accessing on-demand compute resources

Product: Atmosphere

Domain: Science Community: University Research

Development Environment

We have a configurable set of Django Applications that communication with OpenStack to carry out requests for "virtual machine":

• creation
• suspension
• destruction
• block-device attachment
• etc

Those applications declare their deployment variables as YAML for input into Ansible playbooks

The declaration of variables is version controlled, along with a local virtual machine description:

• Vagrant
  • provider: VirtualBox

Ideal Steps

1. clone the deployment variables repo
2. vagrant up
3. run clank
4. profit

The Struggle is real

Use the "sync-folder" as a pass-through from HOST -> GUEST

Made available as /vagrant within GUEST

127.0.0.1 Sweet 127.0.0.1

• dotfiles
• dot-emacs.d

Why emacs?

It could just as easily be vi/vim

Want something that works headless, via a shell session

As a former Sublime Text user, needed to replicate "narrowing" to select files by sub-strings

Ideas? Suggestions?
