Gitconfig Setup
How to Setup Git for Multiple Account in Local Machine
212 views
It's common to have different / multiple Git accounts (personal Github account and work git account). Sometimes it could be a problem if committing changes to work repo using personal git account. It would be a hassle to keep switching git account each time we wanna commit. There's a more convenient way to automatically commit with the right git account according to the folder / repo being worked on. Enter gitconfig
✨.
Follow these steps to setup multiple gitconfig in local machine:
Generate SSH Keys for Each Git Account
SSH keys are used for authentication, and different keys are required for different accounts. You can generate SSH keys using the command ssh-keygen
in the terminal. Make sure you generate different SSH keys for each Git account.
Add SSH Keys to Git Accounts
Once you have generated SSH keys, you need to add them to your Git accounts. You can add SSH keys by going to the settings of your Git account and adding the public key.
Configure GitConfig or SSH Config
There are two ways to achieve resolving correct SSH key for each git account. The first one is folder base (with GitConfig) and the other one is host match (using SSH Config). Use whichever suits to your need.
Option 1: GitConfig Setup
gitconfig
// .gitconfig [user] email = [email protected] name = your_name username = your_username [includeif "gitdir:example/work/folder/"] path = ~/.gitconfig_work [credential] helper = manager
gitconfig
// .gitconfig_work [user] name = your_name email = [email protected] username = your_work_username [core] sshCommand = "ssh -i ~/.ssh/your_work_git_ssh_key_file"
This configuration will match the current working repository folder location.
Option 2: SSH Config Setup
You need to configure the SSH config file to use the correct SSH key for each Git account. You can edit the SSH config file by running the command nano ~/.ssh/config
in the terminal. Add the following lines to the config file:
config
# First account Host github.com-first HostName github.com User git IdentityFile ~/.ssh/id_rsa_first # Second account Host github.com-second HostName github.com User git IdentityFile ~/.ssh/id_rsa_second
You can also use folder matching for the configuration file. For example, if you have multiple Git accounts for work, you can use the following configuration:
config
# Work account Host work.github.com HostName github.com User git IdentityFile ~/.ssh/id_rsa_work
This configuration will match any host that starts with work.github.com
, allowing you to use the same SSH key for all of your Git accounts for work.
Clone Git Repositories
You can now clone Git repositories using the SSH URLs for each account. For example, if you want to clone a repository from the first account, you can use the SSH URL [email protected]:username/repo.git
.
