Before you start, make sure you know:
- Your GitHub Enterprise Server username
- The clone URL for the external repository, such as
git://external-host.com/user/repo.git(perhaps with a
user@in front of the
For purposes of demonstration, we'll use:
- An external account named extuser
- An external Git host named
- A GitHub Enterprise Server personal account named ghuser
- A repository on your GitHub Enterprise Server instance named repo.git
Create a new repository on GitHub Enterprise Server. You'll import your external Git repository to this new repository.
On the command line, make a "bare" clone of the external 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
Push the locally cloned repository to GitHub Enterprise Server 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://HOSTNAME/USER/REPO.git # Pushes the mirror to the new repository on your GitHub Enterprise Server instance
Remove the temporary local repository.
cd .. rm -rf REPO.git
If the repository you are importing contains large files, you may run into a warning or error. For more information on large files and how to manage them, see "About large files on GitHub."
