# Playing with git and GitHub

# Generate a token from GitHub remote repository via -->

1.  Check the value of the origin variable which is the URL of my GitHub repo

**git remote -v**

*origin*[*https://github.com/Titir250/devops-journey.git*](https://github.com/Titir250/devops-journey.git)*(fetch)*

*origin*[*https://github.com/Titir250/devops-journey.git*](https://github.com/Titir250/devops-journey.git)*(push)*

Copy the token from remote GitHub repository

***Click on settings***

***Click on Developer settings***

***Click on tokens(classic) preferably and then Generate a new token. In the token settings fill up desired access, expiry date and once the token is generated copy it and save it.***

2. Now change the origin URL value with the new token generated by GitHub.Add the token value then @github……..

**git remote -v set-url origin***https://ghp\_o3mw5z9YAmNNvLQr980VaqZ0gx6i0W0cDcRi@github.com/Titir250/devops-journey.git*

3.Now the value is changed so when we do push it will hit the new URL with the token

**git remote -v**

*origin*[*https://ghpo3mw5z9YAmNNvLQr980VaqZ0gx6i0W0cDcRi@github.com/Titir250/devops-journey.git*](https://ghpo3mw5z9YAmNNvLQr980VaqZ0gx6i0W0cDcRi@github.com/Titir250/devops-journey.git)*(fetch)*

*origin*[*https://ghpo3mw5z9YAmNNvLQr980VaqZ0gx6i0W0cDcRi@github.com/Titir250/devops-journey.git*](https://ghpo3mw5z9YAmNNvLQr980VaqZ0gx6i0W0cDcRi@github.com/Titir250/devops-journey.git)*(push*)

4.Now the new changes in  the local is pushed to the remote repository using git push command

**git push origin main**

1. Go to your local file system and run git clone command.
    

**git clone**[**https://github.com/Titir250/glearning-git-session.git**](https://github.com/Titir250/glearning-git-session.git)

### Clone a GitHub remote repository using ssh  key pair-->

1. GitHub remote repository and copy the path under the clone section below ssh.

1. Try to clone using git clone shows an error permission denied because there is no ssh key generated in my local system which is not known by github.
    

**git clone**[**git@github.com**](mailto:git@github.com)**:Titir250/devops-journey.git**

*Cloning into 'devops-journey'...*

*The authenticity of host '*[*github.com*](http://github.com)*(20.207.73.82)' can't be established.ED25519 key fingerprint is SHA256:+DiY3wvvV6TuJJhbpZisF/zLDA0zPMSvHdkr4UvCOqU.*

*This key is not known by any other names*

*Are you sure you want to continue connecting (yes/no/\[fingerprint\])? yes*

*Warning: Permanently added '*[*github.com*](http://github.com)*' (ED25519) to the list of known hosts.*

[*git@github.com*](mailto:git@github.com)*: Permission denied (publickey).*

***fatal: Could not read from remote repository.***

*Please make sure you have the correct access rights*

*and the repository exists.*

1. Generate a pair of  ssh key using the ssh-keygen method and copy the public key from there.
    

**I.   Go to the *./ssh* folder to generate the new ssh key pair.**

**cd .ssh**

**ssh-keygen**

*Generating public/private rsa key pair.*

*Enter file in which to save the key (/home/titir/.ssh/id\_rsa): github\_key*

*Enter passphrase (empty for no passphrase):*

*Enter same passphrase again:*

*Your identification has been saved in github\_key*

*Your public key has been saved in github\_*[*key.pub*](http://key.pub)

*The key fingerprint is:*

*SHA256:GJyi/g6Hy+pnVNFKW6lGKflCj++uhV+bk/v7JPVNznY titir@Titir*

*The key's randomart image is:*

**Now 2 keys *github\_key*and*github\_***[***key.pub***](http://key.pub)**private key and public key respectivelyare generated.**

ls

github\_key   github\_[key.pub](http://key.pub)  known\_hosts

**II.   Copy the public key *github\_***[***key.pub***](http://key.pub)***.***

cat github\_[key.pub](http://key.pub)

ssh-rsa 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 titir@Titir

4. Go to GitHub remote repository and paste the public key value there.

***Go to GitHub settings and the SSH and GPG keys and click on new ssh key and save the generated public key there.***

5.  Now go to your local git repository and run the below command to successfully clone the remote git repository.

**GIT\_SSH\_COMMAND="ssh -i /home/titir/.ssh/github\_key" git clone**[**git@github.com**](mailto:git@github.com)**:Titir250/devops-journey.git**
