Is your feature request related to a problem? Please describe.
Docker container engine runs as a daemon service for container management. There is a possibility that developers might use daemonless services like podman .

Describe the solution you'd like
We need to add support for podman as Backend for Dunner. We can implement these functionalities

• Dunner automatically chooses available Backend
• give an option for user to choose one.

@apoorvam @agentmilindu thoughts?

@kmehant I havent personally used daemonless services. But I think it would be a good addition for Dunner. But we need to analyse on how it can be integrated and consequences.
Is there a golang sdk for it? Do many users use this approach with Docker?

On a side note, We had an idea of making dunner as daemon and accessing it using API. But its not yet implemented.

As far as I know, there is no dedicated Go SDK for podman, yet it has to be handled through its command-line interface. Moreover, there is an API for podman which we can use through varlink interface and use it with Go lang further.
Look through this doc and go client example for podman.

This looks awesome.

I have an idea of writing Tekton configuration to use dunner for CI/CD pipelines in a Kubernetes cluster.
