I was thinking of trying this out and deploying to Fargate. This particular one appears to be officially maintained by the nodebb guys:
https://hub.docker.com/r/nodebb/docker
Using this tool below I can deploy easily, and I can also manage SSL certs and load balancing (which I think will negate the need for nginx):
https://somanymachines.com/fargate/
I think I would just need a mongo instance either in EC2 or as another container in Fargate, and then deploy the nodebb container. Thoughts? Am I missing something?
Has anyone tried using AWS DocumentDB in place of Mongo? It's supposed to be compatible.
