hey, where did we configured, which services to be rum on which instances??

Great video.. but I wonder if your networks (frontend, backend) are overlays? Or it's only working on one machine only. Because all you did was making Dockerfiles and push them. We never saw how it really works. Would be more simple if it was only docker-compose file without Dockerfile. Ex: Nginx, postgresql, traefik, authelia (authentik), django, redis, heimdall, socket-proxy... etc... I think the biggest problem with swarm, is communication between machines. How to share the same networks for databases or reverse proxies. How to share secrets or environment variables. Why should we use replicas. What are "services". Why do we push images and where do we push it? Should we create a registry container? Can consul be a good thing?

Is there any reasons why you moving postgres to a seperate linode?

For a recommendation, databases should be in different servers from applications. But for a tight budget, setup application and database on the same server.

Databases are different beasts than applications because require different replication, loadbalancing and snapshotting strategies based on master-replica relations. These operations are not easy to manage that's why most of the time architects just delegate those tasks to dedicated database entities like those linodes he chose.
