   2. Select a branch from the Branch drop-down list.

   3. Add an object path file in the Object Path text field.

      A sample is as shown in the following figure.

      

   4. Click Save.

Pushing Commits to GitLab

After you link notebooks with a GitLab repository, you can start using the notebook to push commits to the GitLab directly from a notebook associated with a running cluster.

Before you push the commits, ensure that the following requirements are met:

• The GitLab profile token must have write permissions for the repository to push commits.

• The associated cluster must be running.

Steps

1. Click Manage notebook versions that is on the top-right of the notebook. It expands and provides the version details.

2. Click the Push icon to commit. A dialog opens to push commits. The following figure shows the version details and the Push to GitLab dialog.

   

3. Add a commit message and click Save to push the commit to the GitLab repository. You can use the option force commit to force push over the old commit (irrespective of any conflict).

Note

2. Link the cloned notebook to the same GitLab repo branch and path as the original notebook.

3. Checkout the latest version of the cloned notebook.

4. Manually port changes from the original notebook to the cloned notebook.
