All options I can think of for git deployment

git_options.pp

node testnode {
    git::repository { "repo":
        # default values
        server_user => "root",
        owner_user  => "root",
        owner_group => "root",
        target_dir  => "repo",
        githost     => "githost",
        gituser     => $server_user,
        target_dir  => $name,

        # repository to clone
        repository  => "${gituser}@${githost}:/repo/${name}.git",

        # revision to check out, pick one or none, default values depends
        # on deploy_mode:
        #   deploy_mode 'development', checks out latest default branch on
        #     first clone, does no updates afterwards
        #   deploy_mode 'production', checks out latest release-# tag for
        #     each run
        branch      => "master",
        revision    => "6f32f21e",
        tag         => "release-3",

        # possible values, 'development', 'production'
        # default is assumed to be 'development', but can also be overridden
        # by setting $git_deployment_mode before calling the resource
        deploy_mode => "development",

        # required values
        export_dir  => "/path/to/export/directory",
    }
}
