title: How to run a specific job in gitlab CI
body: <p>We are facing a problem where we need to run one specific job in gitlab CI. We currently not know how to solve this problem. We have multitple jobs defined in our <code>.gitlab-ci.yml</code> but we only need to run a single job within our pipelines. How could we just run one job e.g. <code>job1</code> or <code>job2</code>? We can't use <code>tags</code> or <code>branches</code> as a software switch in our environment.</p>
  
  <h3>.gitlab-ci.yml:</h3>
  
  <pre><code>before_script:
    - docker info
  
  job1:
    script:
      - do something
  
  job2:
    script:
      - do something
  </code></pre>
