Hi@akhtar,
Before starting Podman service, you have to know something. In case of docker when you launch an container it goes to your docker engine service and from there it connects to your host kernal. So if your docker engine corrupts than all the containers shut down. So to avoid this Podman comes into the place. Podman doesn't have any service. When you launch one container, it connects to your kernal directly. So it is faster that docker as well.
So, you don't have to start Podman service. You have to install this software and use it.
Hope this will help you.
