Configure mirroring on an existing project to sync with a remote repository.

## Synopsis

Configure repository mirroring for an existing GitLab project.

The GitLab project must already exist. This command configures mirroring
on existing projects but does not create new projects.

Mirror types:

- Pull mirror: Syncs changes from an external repository to your GitLab project. The external repository is the source of truth. Use pull mirrors to sync from GitHub, Bitbucket, or other GitLab instances.
- Push mirror: Syncs changes from your GitLab project to an external repository. Your GitLab project is the source of truth. Use push mirrors to sync to GitHub, Bitbucket, or other GitLab instances.

Authentication:

- For pull mirrors from private repositories, embed credentials in the URL: `https://username:token@gitlab.example.com/org/repo`
- For push mirrors to private repositories, configure credentials in the GitLab UI or use SSH URLs with deploy keys.

```plaintext
glab repo mirror [<id | url | path>] [flags]
```

## Examples

```console
# Create a project, then configure pull mirroring
glab repo create mygroup/myproject --public
glab repo mirror mygroup/myproject --direction=pull --url="https://gitlab.example.com/org/repo"

# Configure pull mirroring from a private repository
glab repo mirror mygroup/myproject --direction=pull --url="https://username:token@gitlab.example.com/org/private-repo"

# Configure pull mirroring for protected branches only
glab repo mirror mygroup/myproject --direction=pull --url="https://gitlab.example.com/org/repo" --protected-branches-only

# Configure push mirroring to another GitLab instance
glab repo mirror mygroup/myproject --direction=push --url="https://gitlab-backup.example.com/backup/myproject"

# Configure push mirroring and allow divergent refs
glab repo mirror mygroup/myproject --direction=push --url="https://gitlab-backup.example.com/backup/repo" --allow-divergence
```
