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

Linux

# 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

GitHub Account

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:

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

cd catch-up
./catch-up.sh

Branches

git checkout -b branchname

git branch

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?

# Show current branch
$ git branch

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