Import bare repositories (deprecated) (FREE SELF)

WARNING: The Rake task for importing bare repositories was deprecated in GitLab 15.8 and will be removed in GitLab 16.0.

Alternatives to using the gitlab:import:repos Rake task include:

Rake tasks are available to import bare repositories into a GitLab instance. When migrating from an existing GitLab instance, and to preserve ownership by users and their namespaces, migrate projects using either:

When you import a repository:

  • The owner of the project is the first administrator.
  • The groups are created as needed, including subgroups.
  • The owner of the group is the first administrator.
  • Existing projects are skipped.
  • Projects in hashed storage may be skipped. For more information, see Importing bare repositories from hashed storage.
  • The existing Git repositories are moved from disk (removed from the original path).
  • You must manually push Git LFS objects.

To import bare repositories into a GitLab instance:

  1. Create a new folder to import your Git repositories from. You can also import projects into a (sub)group's namespace, instead of the administrator's namespace. To do so, create subfolders and give ownership and read/write/execute permissions of those subfolders to the git user and its group:

    sudo -u git mkdir -p /var/opt/gitlab/git-data/repository-import-$(date "+%Y-%m-%d")/<optional_groupname>/<optional_subgroup>

  2. Copy your bare repositories inside this newly created folder. Note:

    • Any .git repositories found on any of the subfolders are imported as projects.
    • Groups are created as needed, these could be nested folders.

    For example, if we copy the repositories to /var/opt/gitlab/git-data/repository-import-2020-08-22, and repository A must be under the groups G1 and G2, it must be created under those folders: /var/opt/gitlab/git-data/repository-import-2020-08-22/G1/G2/A.git.

    sudo cp -r /old/git/foo.git /var/opt/gitlab/git-data/repository-import-$(date "+%Y-%m-%d")/<optional_groupname>/<optional_subgroup>

# Do this once when you are done copying git repositories
sudo chown -R git:git /var/opt/gitlab/git-data/repository-import-$(date "+%Y-%m-%d")

    foo.git must be owned by the git user and git users group.

    If you are using an installation from source, replace /var/opt/gitlab/ with /home/git.

  3. Run the following command depending on your type of installation:

    • Omnibus Installation
    sudo gitlab-rake gitlab:import:repos["/var/opt/gitlab/git-data/repository-import-$(date "+%Y-%m-%d")"]
    • Installation from source. Before running this command you must change to the directory where your GitLab installation is located:
    cd /home/git/gitlab
sudo -u git -H bundle exec rake gitlab:import:repos["/var/opt/gitlab/git-data/repository-import-$(date "+%Y-%m-%d")"] RAILS_ENV=production

Importing bare repositories from hashed storage

Projects in legacy storage have a directory structure that mirrors their full project path in GitLab, including their namespace structure. This information is leveraged by the bare repository importer to import projects into their proper locations. Each project and its parent namespaces are meaningfully named.

However, the directory structure of projects in hashed storage do not contain this information. This is beneficial for a variety of reasons, especially improved performance and data integrity. See Repository Storage Types for more details.

The repositories that are importable depends on the version of GitLab.

GitLab 10.3 or earlier

Importing bare repositories from hashed storage is unsupported.

GitLab 10.4 and later

To support importing bare repositories from hashed storage, GitLab 10.4 and later stores the full project path with each repository, in a special section of the Git repository's configuration file. This section is formatted as follows:

[gitlab]
  fullpath = gitlab-org/gitlab

However, existing repositories were not migrated to include this path.

Bare repositories are importable if the following events occurred to the repository in GitLab 10.4 and later:

  • Created
  • Migrated to hashed storage
  • Renamed
  • Transferred to another namespace
  • Ancestor renamed
  • Ancestor transferred to another namespace

Bare repositories are not importable by GitLab 10.4 to GitLab 11.6, if all the following are true about the repository:

  • It was created in GitLab 10.3 or earlier.
  • It was not renamed, transferred, or migrated to hashed storage in GitLab 10.4 to GitLab 11.6.
  • Its ancestor namespaces were not renamed or transferred in GitLab 10.4 to GitLab 11.6.

In GitLab 11.6 and later, all bare repositories are importable.

To manually migrate repositories yourself (for GitLab 10.4 to GitLab 11.6), you can use the Rails console to do so. In a Rails console session, run the following to migrate a project:

project = Project.find_by_full_path('gitlab-org/gitlab')
project.set_full_path

In a Rails console session, run the following to migrate all of a namespace's projects (this may take a while if there are thousands of projects in a namespace):

namespace = Namespace.find_by_full_path('gitlab-org')
namespace.send(:write_projects_repository_config)

Push Git LFS objects

The import task doesn't import Git LFS objects. You must manually push the LFS objects to the newly created GitLab repository using the following command:

git lfs push --all
