Quick and dirty GitHub for beginers – your first commit


Jonathan Frappier Virtxpert

I started my Ansible series really with the intention of getting to know Git/GitHub a bit better but Ansible was so awesome I couldn’t put it down.  Now that I have built a couple of example playbooks its time to “commit” those into GitHub.  For starters, we need Git/GitHub installed on our system.  In my case I am doing everything from my Ansible server, though you may want to do this on another system.  Thanks to yum, the install is pretty easy

yum install git

I had already run this on my Ansible server so I could “pull” the Ansible code.  Now I want to setup my username so:

git config --global user.name "yourusername"

Next register your email account for your GitHub account

git config --global user.email "youremail"

Now on to authentication, it’s high time I stop using passwords for everything and setup SSH keys so, lets do that.  To create the public key enter:

ssh-keygen -t rsa -C "email@example.com"
  • While logged in as root it will save to /root/.ssh/id_rsa)
  • Next enter your secure password
  • With the key now created, log into GitHub and click on the gear icon (Settings) in the upper right corner
  • Click on SSH keys
  • Click the add SSH keys button
  • Provide a title such as “ansible VM” or whatever used to identify the computer
  • Back in your terminal window type

less /root/.ssh/id_rsa.pub

  • Copy the contents of the file and paste it into the Key text box
  • Click the Add key button
  • Back in your terminal window type

ssh -T git@github.com

  • Accept the key from github.com
  • Enter the pass phrase for your key
  • You should now be logged into GitHub with your keys!

  • Now, switch the to folder where you are saving your Ansible playbooks
  • Type git init
  • Type git add .
  • Type git commit -m ‘playbooks’
  • Find the URL from your Git repository (create one if you haven’t), make sure to click on SSH, not HTTPS and copy that

  • Type git remote add origin git@github.com:user/repository.git
  • Type git remote -v
  • Type git push origin master then enter the pass phrase for your SSH key

Now if I go to my repository, I can see my .yml files checked in!

From now on, as we create or update our playbooks we can check them into GitHub for safe keeping and sharing!
