Protip: if you want to use Podman (or Podman Desktop) with Docker Compose compatibility, you'll have a better time installing podman-compose [1] and setting up your env like so:

  alias docker=podman
  
  # If you want to still use Docker Compose
  # export PODMAN_COMPOSE_PROVIDER=docker-compose
  
  # On macOS: `brew install podman-compose`
  export PODMAN_COMPOSE_PROVIDER=podman-compose
  export PODMAN_COMPOSE_WARNING_LOGS=false

Most of my initial issues transitioning to Podman were actually just Docker (and Docker Desktop) issues.

Quadlets are great and Podman has a tool called podlet [2] for converting Docker Compose files to Quadlets.

I prefer using a tool like kompose [3] to turn my Docker Compose files into Kubernetes manifests. Then I can use Podman's Kubernetes integration (with some tweaks for port forwarding [4]) to replace Docker Compose altogether!
