Configuring SSH for Git and push

 

Youtube link: Navigation to pefrom lab

This lab has three parts:

Part1: Create a github account

  1. Go to github.com
  2. Incase you have existing github account please use or sign up for a new account
  3. If you choose to sign up for a new account, click ‘Sign up’ at the top right
    1. Create a username. You might need to use a personal email address
    2. You will need to check your email and verify that your email address is real

Part2: creating repo on github

Create a private repository in your GitHub account called “gittraining”
a. Name: repo-lab
b. Choose ‘Public’
c. Do not initialize with a README
d. Click the green ‘Create Repository’ button

Copy the SSH URL under ‘Quick Setup’

On your remote putty: in the my-repo directory:

# Below are the example, please change the command as per your git repo
git branch -M main
git remote add origin git@github.com:amitopenwriteup/gittraining.git
git push -u origin main

#This should fail

Part 3: Configuring SSH Connections to GitHub

To fix this, we need to follow these four steps:
a. Create an SSH key pair
b. Add the PUBLIC key to GitHub
c. GitHub will use the PUBLIC key that you uploaded to GitHub in step ‘B’ to
decrypt the communication from the PRIVATE key from your workstation,
AUTHENTICATING you as an authorized user

 ssh-keygen -t rsa -b 4096

#Press enter, no passphrase

Your identification has been saved in /root/.ssh/id_rsa [Private key]
Your public key has been saved in /root/.ssh/id_rsa.pub [Public key]

 cat /root/.ssh/id_rsa.pub
#copy the value

Now go to github.com

Go to: Settings -> SSH & GPG keys -> SSH Keys
Click ‘New SSH key’
Title “Public repo-key”

Add keys

Now try to push it

git push origin main
