[QGIS-Developer] [RHEL][QGIS Server] Installation questions and advices

[João Gaspar]

Dear Alessandro and Rizky,
sorry for my delay in the answer. Many thanks for sharing your feedback.

After your feedback, I found that are implementing as well an alternative
for docker-compose compatible with podman.

https://github.com/containers/podman-compose

So I think is good news as well.

Once again thank you for your time.

Best regards,
João Gaspar
