title: Use az webapp deployment source to deploy code from git but when the app is in a git repository subfolder
body: <p>I'm trying to deploy code from my gitlab CI runner to Azure.  I'm using the <code>az webapp deployment</code> to do the job:</p>
  <pre class="lang-sh prettyprint-override"><code>az webapp deployment source config --branch master --manual-integration --name [myWebApp] --repo-url [git url] --app-working-dir [folder] --resource-group [myResourceGroup]
  
  </code></pre>
  <p>But there is a problem, the default working directory is the git 's root folder. My application is inside a child folder from root. I check the <a href="https://docs.azure.cn/zh-cn/cli/webapp/deployment/source?view=azure-cli-latest" rel="nofollow noreferrer">command configuration</a> and I saw <code>--app-working-dir</code> which does what I want, again, but only works if <code>--cd-project-url</code> is set (I don't need and I'm not using  VSTS). Also, there is no example available of using this config. I'm looking to have a command set similar to what I used when deploying via azure cloud shell: <code>cd &lt;app-folder&gt;; az webapp up --sku B1 --name &lt;app-name&gt;</code>. There is a way to do the deploy in a simpler form?</p>
