title: How can I change a setting in appsettings.json after auto-deploy?
body: <p>I have an ASP.NET Core application going on an have setup Github auto-deploy on it. But since it's an open repo I obviously don't want to upload my correct configuration file.</p>
  
  <p>What I'd like to do is to replace some strings in the appsettings.json after a github auto deploy.</p>
  
  <pre><code>"AppSettings": {
      "Token": "my super duper secret token"
  }
  </code></pre>
  
  <p>How can I change <code>my super duper secret token</code> to my real token after a github deploy on Azure?</p>
