docker-compose

docker-compose version included in Raspbian 11 Bullseye is outdated, but will run most modern configurations if you add the following line to docker-compose.yaml file:

version: "3"

For some reason, having this property in a yaml file will raise a warning in newer versions of docker-compose.
