Lesson 14: Review
=================

Today's Goals
-------------

* Working VM
* Run Systemview app
* Connect to Systemview from browser in host
* Understand what's happening

How to set up a VM
------------------

Enable VirtualBox (VT extensions)
---------------------------------

Install `VirtualBox`_

Install `Vagrant`_

.. _VirtualBox: https://www.virtualbox.org/wiki/Downloads
.. _Vagrant: http://www.vagrantup.com/

Linux
-----

.. code-block:: bash

    # clone
    git clone https://github.com/DevOpsBootcamp/devopsbootcamp-vagrant.git

    # start up
    cd devopsbootcamp-vagrant
    vagrant up

    # access vm
    vagrant ssh

IRC
---

* Use the `LUG guide`_ 
* #devopsbootcamp on irc.freenode.net
* Also join the `Mailing List`_

.. _LUG guide: http://lug.oregonstate.edu/blog/irc/
.. _Mailing List: http://lists.osuosl.org/mailman/listinfo/devops-bootcamp

GitHub Account
--------------

:SSH keys:

::

  ssh-keygen -t rsa

Your public key is in ``~/.ssh/id_rsa.pub`` by default. 

GitHub -> Account Settings (icon in upper right) -> SSH keys -> Add SSH key

Joining the Github Org
----------------------

* Ping Ramereth in the IRC channel to add you

Installing the Web App
----------------------

Prerequisite tools
------------------

On host machine, in ``devopsbootcamp-vagrant`` directory: 

::

    git pull
    vagrant up
    vagrant ssh

The Magic Script
----------------

Now that you're in the guest machine: 

.. code-block:: bash

    git@github.com:DevOpsBootcamp/catch-up.git

    cd catch-up
    ./catch-up.sh

Branches
--------

:Start one with:

::

  git checkout -b branchname

:Which are you on:

::

  git branch


:Switch with:

::

  git checkout branchname


Connecting to the App
---------------------

In the guest machine, with ``virtualenv`` activated, ``python systemview.py``

Point the browser of your host machine at http://127.0.0.1:5050

If changes in the app don't show up in your browser, use ``F5`` to hard refresh

Where am I?
-----------

In virtual machine?
-------------------

* Did you ``vagrant ssh``?

In a repo?
----------

* ``git status``

On a branch?
------------

.. code-block:: bash

    # Show current branch
    $ git branch 

    # create new branch, called branchname
    $ git checkout -b branchname
