Hey!

I created a Repository in GitLab.

How?

Go to https://gitlab.com

Register and Login with Valid credentials.

Go to https://gitlab.com/dashboard/projects

Click on New Project.

• Designing AWS Environments
• Machine Learning with R Cookbook
• Natural Language Processing with Java
• Deep Learning Projects with PyTorch [Video]
• Practical AWS Networking
• Learning Azure Functions
• Jenkins Continuous Integration Cookbook
• Jenkins Essentials – Second Edition 
• DevOps for Web Development
• Implementing DevOps with Microsoft Azure
• DevOps Bootcamp
• Jenkins Essentials

Give Proper name and Select Visibility. Click on Create.

You will get command line instructions on Git global setup, Create a new repository, Existing folder, and Existing Git repository.

In my case, I had repository available in File System.

So I tried to follow instructions for Existing folder.

cd existing_folder
git init
git remote add origin git@gitlab.com:mitesh.soni83/petclinic-blueocean.git
git add .
git commit -m "Initial commit"
git push -u origin master

However, while Pushing the code with git push -u origin master, I faced errors.

$ git push --set-upstream origin master
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.

Solution:

Go to Git Bash

Generate SSH Keys using following command:  ssh-keygen -t rsa -b 4096 -C "xxxxxxx.xxxxxxx@gmail.com"

It will generate Public and Private Key in a Directory.

Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/Mitesh/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/Mitesh/.ssh/id_rsa.
Your public key has been saved in /c/Users/Mitesh/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:f3n+3r7fO9Y6DrztlKXj2cyLQbZ08pqeabHGRHcNb1I mitesh.soni83@gmail.com
The key's randomart image is:
+---[RSA 4096]----+
| |
| . F|
| +.|
| ..==|
| S .=.+o|
| . .++=+ |
| . BoE..|
| . &DO+|
| =YXX^|
+----[SHA256]-----+

Go to that directory and open id_rsa.pub in Editor.

Copy the Key content.

Go to GitLab.

Go to https://gitlab.com/profile and click on SSH Keys.

Paste your public SSH key, which is usually contained in the file ‘~/.ssh/id_rsa.pub’ and begins with ‘ssh-rsa’. Don’t use your private SSH key.

Click on Add Key.

Verify newly added key in Gitlab.

Now use git push –set-upstream origin master

$ git push -u origin master
