Cannot run opentelemetry-demo using podman-compose

[konstantinblaesi]

Describe the bug
The opentelemetry-demo suggests docker compose and running it via podman-compose fails

To Reproduce
For steps see
https://opentelemetry.io/docs/demo/docker-deployment/#get-and-run-the-demo

Expected behavior
Demo starts

Actual behavior
Demo never starts

• complains about unknown cache_from in docker-compose.yml
• then fails because variables from .env are not visible when podman-compose builds services using their Dockerfiles

$ podman-compose version
podman-compose version 1.5.0
podman version 5.8.1

Environment:

• OS: Fedora 43
