deploy with docker-compose.yaml

Not currently, unfortunately.

One approach is to make separate apps and then get them to communicate using the encrypted, private network (using .internal hostnames) …

What is an instance and how do I create multiple instances?

Would you mind sharing your docker-compose file here? In Fly world, you’ll need to create one app per compose entry and then make sure they know each others’ internal hostnames (like <app>.internal). You’ll also need to manually create volumes if your compose app relies on disks.

… or you would run multiple processes within one app. Then you would need an additional process in that app to keep them all running. For example using supervisor. This page has some more details about that multi-process approach:
