title: Multiple commands in the same build step in Google Cloud Builder
body: <p>I want to run our automated backend test suite on Google Cloud Builder environment. However, naturally, I bumped into the need to install various dependencies and prerequisites within the Cloud Builder so that our final test runner (<code>php tests/run</code>) can run.</p>
  
  <p>Here's my current cloudbuild.yaml:</p>
  
  <pre><code>steps:
  
    - name: 'ubuntu'
      args: ['bash', './scripts/install-prerequisites.sh', '&amp;&amp;', 'composer install -n -q --prefer-dist', '&amp;&amp;', 'php init --overwrite=y', '&amp;&amp;', 'php tests/run']
  </code></pre>
  
  <p>At the moment, the chaining of multiple commands doesn't work. The only thing that's executed is the <code>bash ./scripts/install-prerequisites.sh</code> part. How do I get all of these commands get executed in order?</p>
