Unfortunately, you cannot (easily) deploy containers to App Engine Flex this way.

At its simplest, App Engine Flex is a service that combines a load-balancer, an auto-scaler and your docker image. Your image when run as a container is expected to provide an HTTP/S endpoint on port 8080.

There are 2 ways that App Engine could support your deployment but it does neither:

  • It bundles a WordPress app image and a MySQL image into a single "pod" and exposes WordPress' HTTP port on :8080. This isn't what you want because then each WordPress instance has its own MySQL instance.

  • It separates the WordPress app into one service and the MySQL app into another service. This is closer to what you want as you could then scale the WordPress instances independently of the MySQL instances. However, databases are the definitive stateful app and you don't want to run these as App Engine services.

The second case suggests some alternative approaches for you to consider:

  1. Deploy your WordPress app to App Engine but use Google Cloud SQL service link.
  2. If you don't want to use Cloud SQL, you could run your MySQL database on Compute Engine link.
  3. You may wish to consider Kubernetes Engine. This would permit both the approaches outlined above and there are tools that help you migrate from docker-compose files to Kubernetes configurations link.

Since you're familiar with App Engine, I recommend you consider using option #1 above (Cloud SQL)
