I'm trying to figure out how to deploy Docker Compose applications on AWS, using the Karakeep project (an open-source bookmark database) as an example. I found the project's Docker Compose file and I'm curious about the steps and best practices for transitioning from a local Docker Compose setup to AWS container orchestration services. Any tips or tools I should be aware of?

You might want to check out Komposer. It can convert your Docker Compose yaml files to Kubernetes yaml, which would then allow you to use EKS. It's a handy tool for transitioning to the AWS ecosystem if you're looking to dive into Kubernetes.
ECS is a good option for running your images and you could use EFS for persistent storage. You can also utilize service discovery (CloudMap) to manage service hostnames. Essentially, you should break down your Docker Compose structure and map those components to their respective AWS services. Just remember, AWS doesn't have a straightforward way to run Docker Compose unless you resort to using an EC2 instance with Docker installed. The recommended path is to rebuild the orchestration with ECS or EKS, and consider using Fargate to simplify management. It does take a bit of setup to make the containers accessible to each other, though.
That sounds like a good plan! I had a similar experience. It seems like using EKS is a bit more involved, but at the end of the day, converting Docker Compose into ECS or EKS setup is the way to go.
