Unraid “supports” docker compose. You can install and use it but you won’t be able to utilize how unraid handles docker containers.
All that unraid does is make docker more accessible for the normal user. In the end the container template constructs a docker run command.
So you could use portainer to manage stacks through a webui or install compose and have to SSH into the unraid server all the time.
