title: How to specify image platform in gitlab-ci.yml
body: <p>I am trying to build CI pipeline which does build for particular image. In the CI file however, I could not find a way to specify image platform.</p>
  <pre><code>stages:
    - build
    - deploy
  
  build_j:
    image: customServer/debian/jessy
  </code></pre>
  <p>I checked <a href="https://docs.gitlab.com/ee/ci/docker/using_docker_images.html" rel="nofollow noreferrer">Docker Images doc</a> and <a href="https://docs.gitlab.com/ee/user/packages/container_registry/#container-registry-examples-with-gitlab-cicd" rel="nofollow noreferrer">this</a> but could not find any example. Alternative way perhaps is to pull image explicitly and run commands using script.</p>
  <pre><code>docker pull debian:jessy -platform i386
  </code></pre>
