Help Needed to go from Docker-Compose to fly.toml

Hi, I’m trying to deploy a prototype of an app I have working locally.
It’s made up of a docker-compose.yml file I’ll post the contents of in a moment; but it’s basically an instance of InfluxDB, Telegraf, and Grafana.

I know that Fly.io requires a fly.toml to configure my app but I don’t know how to translate my docker-compose.yml file to its equivalent fly.toml configuration.

I understand that each of my services should likely be its own app, running separately; but as I mentioned, this is just going to be a small prototype to play with. It’s nothing I plan to release and sell in this state.

I’ve read through similar-sounding topics in these forums and read through the documentation but still could not figure out how to go about this. I would appreciate any help or guidance. Thank you!

Does this help? Using Containers with Flyctl

I’ll give it a read and try it later this evening when I get home. Thank you for sharing.
