Prerequisite
- GitLab account
- macOS
If you want to clone a repository from GitLab, there are 2 ways to do it.
The first choice is usingHTTPS, but you need to insert your GitLab username and password every time you clone a repository.
The second choice is usingSSH key. By using SSH key, you can clone a repository from GitLab without inserting username and password. Because, SSH key will handle the authentication.
Today, we will learn how to set GitLab SSH Key on macOS.
Generate SSH Key
- Open your terminal, go to .ssh directory
cd ~/.ssh- Create your SSH Key. We will use RSA SSH key configuration.
ssh-keygen-t rsa-C"your_email_address"- You'll see a message to insert file name for SSH key. For example, I insert:
id_rsa_gitlab_key
Generating public/private rsa key pair.Enter fileinwhich to save the key(/home/user/.ssh/id_rsa):- Next, you'll be asked to enter passphrase. Just leave it empty
Enter passphrase(emptyforno passphrase):Enter same passphrase again:- Congratulations, you just create your own SSH Key. To check SSH key exist or not, run:
ls-al- You will find two files:
id_rsa_gitlab_key // private keyid_rsa_gitlab_key.pub // public keyRegister SSH Key
To make sure your mac able to authenticate automatically with GitLab, you need to register your SSH key to SSH agent in your mac.
- Start the ssh-agent.
eval$(ssh-agent-s)- Add your SSH key to SSH agent.
ssh-add-K ~/.ssh/id_rsa_gitlab_key- Open SSH config file.
nano ~/.ssh/config- To make sure your SSH key added automatically to SSH agent after a reboot (or logout/login), we need to set config file.
Host gitlab.com AddKeysToAgent yes UseKeychain yes # IdentityFile is your ssh key file location IdentityFile ~/.ssh/id_rsa_gitlab_keySave config file by using
ctrl + x.Check your SSH key in SSH agent.
ssh-add -l- You will see your SSH key has been registered to SSH agent.
Insert SSH Key to GitLab Account
- Copy your SSH Key. This key will be copied to your GitLab account.
pbcopy < ~/.ssh/id_rsa_gitlab_key.pub- Go to gitlab.com, then goProfile >> SSH Keys menu (
https://gitlab.com/profile/keys).
Paste your SSH Key toKey input, and also add theTitle.
PressAdd Key button.
To test whether your SSH key was added correctly, run:
ssh-T git@gitlab.com- It should return:
Welcome to GitLab, @your_gitlab_username!Great, now you can clone and push a repository in GitLab, getting work done and have a time with your family 😁 .
