Works like a charm on a Fedora + podman compose !! I had to tweak the ollama-service a tiny bit with Philippe Charrière's help:

services:
  # https://cheshirecat.ai/local-models-with-ollama/
  ollama-service:
    container_name: ollama_pi_local
    user: root
    image: ollama/ollama:0.1.27
    volumes:
      - ollama-data:/root/.ollama
    ports:
      - 11434:11434
volumes:
  ollama-data:
