title: How to create a merge request at the end of a successful pipeline in Gitlab?
body: <p>I'm very new to gitlab and gitlab CI and I have put a pipeline in place that is successfully completing.
  My master and development branches are protected so a merge request is required so that another dev in the group can review the code and comment before merging.
  I was wondering if it is possible to generate this merge request at the end of this pipeline. Is there a setting for this in the gitlab repository or do I have to create a script to achieve this?

  Just before posting this I came across <a href="https://docs.gitlab.com/ee/api/merge_requests.html#create-mr" rel="noreferrer">this section of the gitlab docs</a> <br/>
  I'm using gitlab-runner 11.0.0 on ubuntu 18.04</p>
