title: Connect with existing MySQL database (OVH) from Cloud Functions
body: <p>I have an existing database hosted by OVH and managed by PhpMyAdmin.
  On the other side, I also have a Firebase project where I use several Cloud Functions.</p>
  <p>I would like write, in my existing OVH database, datas from my Firestore collections (thanks to Cloud Functions).</p>
  <p>Is there a way to connect my Cloud Functions to an existing database ?</p>
  <p>I did read than is possible to connect Cloud Functions to MySQL database with Cloud SQL but it seems only for new database created from Cloud Platform, which is not my usecase as my database is already created and hosted by OVH.</p>
  <p>Thank you for your help!</p>
