This is my collection of .yml files for docker.
These containers are running on my raspberry Pi 4 (2GB Version), Raspberry Pi OS 64bit.
Docker is installed like usual and docker swarm is enabled: docker swarm init
To use it yourself, clone the repository, cd inside it and run e.g.
docker stack deploy -c XXX.yml YYY
Where XXX.yml is the file/container you want to run and YYY is the name docker assigns to it. For me XXX=YYY (I name the containers like the files)
