title: Gitlab-runner in docker - How to run as non root
body: <p>I am trying to automate ios build and deployment using fastlane and gitlab ci. My gitlab-runner installed in a docker container. Since runner in docker container runs as root (sudo), pod install gets failed as it does not allow to execute as root user. Anyone faced similar problem? I have tried searching in stackoverflow without success.</p>
  <pre><code>$ bundle exec pod install
   bundler: failed to load command: pod (/builds/root/fastlaneexample/vendor/bundle/ruby/2.7.0/bin/pod) CLAide::Help: [!] You cannot run CocoaPods as root.
  </code></pre>
