Need help on deploying to Flexi environment

[ankit...@gmail.com]

 Hello ,

   I have several Go docker containers which are REST APIs running on a single compute engine VM. I would like to migrate to App Engine how do i go about designing my solution. I have mysql DB also so I would like to use Cloud SQL.

As far as App Engine Flexi is concerned my understanding is that there are multiple ways to deploy 

 1) Build your own docker container

  2) gcloud app deploy

  

 How do i start ? Any help appreciated thanks in advance

Regards
