**Note: The install was trying to modify the docker compose file (when podman is being used)


The following error was also seen in the 

#1: Jul 30 03:03:41xxxxxxxxxxxxx quadlet-generator[6704]: error loading "/etc/containers/systemd/cmp-appneta-01/cmp-appneta-01-sequencer.container", file contains line 25: “__PORTS__” which is not a key-value pair, group, or comment

Environment

RHEL 9
Podman 5.4

Cause

Existence of docker binaries caused the setup.sh and config.sh scripts to pick up docker as an engine. If found docker will take precedence over podman. In this case
  the podman-docker package was also installed causing the install to pickup docker as an engine.

Resolution

Remove the podman-docker package and reinstall or perform the workaround below.

Workaround: modify the setup.sh and config.sh scripts

setup.sh
config.sh


In BOTH files find the CONTAINER_ENGINES= line and remove docker



example

CONTAINER_ENGINES='podman'




Rerun the installation

./setup.sh install
