If GitHub Importer is not suitable for your purposes, such as if your existing code is hosted on a private network, then we recommend importing using the command line.

Before you start, make sure you know:

  • Your GitHub username
  • The clone URL for the external repository, such as https://external-host.com/user/repo.git or git://external-host.com/user/repo.git (perhaps with a user@ in front of the external-host.com domain name)

For purposes of demonstration, we'll use:

  • An external account named extuser
  • An external Git host named https://external-host.com
  • A GitHub personal user account named ghuser
  • A GitHub repository named repo.git
  1. Create a new repository on GitHub. You'll import your external Git repository to this new repository.
  2. On the command line, make a "bare" clone of the repository using the external clone URL. This creates a full copy of the data, but without a working directory for editing files, and ensures a clean, fresh export of all the old data.

    git clone --bare https://external-host.com/extuser/repo.git
    # Makes a bare clone of the external repository in a local directory
    
  3. Push the locally cloned repository to GitHub using the "mirror" option, which ensures that all references, such as branches and tags, are copied to the imported repository.

    cd repo.git
    git push --mirror https://github.com/ghuser/repo.git
    # Pushes the mirror to the new GitHub repository
    
  4. Remove the temporary local repository.

    cd ..
    rm -rf repo.git
