title: How to pass parameter as a file in AWS CloudFormation deploy?
body: <p>I was trying to update the existing CloudFormation stack with the below command.</p>
  <pre class="lang-sh prettyprint-override"><code>aws cloudformation deploy
  </code></pre>
  <p>there is no option to pass parameter <strong>file</strong> with <strong>deploy</strong> option. we tried to pass parameter file with --parameter-overrides but it's giving the below error.</p>
  <blockquote>
  <p>value passed to --parameter-overrides must be of format Key=Value</p>
  </blockquote>
  <p>the command we try to execute is</p>
  <pre class="lang-sh prettyprint-override"><code>aws cloudformation deploy --template-file sg.yml --stack-name Common-SG --parameter-overrides ip.json --no-execute-changeset
  </code></pre>
  <p>is there any way to pass the parameters in file with <strong>aws cloudformation deploy</strong></p>
