Use the `healthcheck` directive and a sidecar container with a shared `network_mode` to monitor application health without modifying the main image.
Use the `depends_on` directive with a `service_healthy` condition to ensure dependent services only start after their dependencies are fully operational.
Set CPU and memory constraints using `deploy.resources.limits` and centralize these definitions with YAML anchors to avoid duplication.
Improve maintainability by moving common service definitions to a base file using `extends` and splitting a large stack into multiple files using `include`.
Use `profiles` to conditionally enable services for specific environments and use override files to apply different configurations like resource limits for production.
Use the `dyslint` tool to automatically check compose files for best practices, identify potential security issues, and apply automated fixes.
Use the `kompose` tool to automatically convert a Docker Compose application into Kubernetes manifests as a starting point for migrating to Kubernetes.
