Capability to select container driver

[corinz]

I am using Podman, and unable to issue faas-cli commands to build using the podman driver. Does faas-cli have the capability to select an alternative driver?

Expected Behaviour

faas-cli would work with podman by selecting the driver

Current Behaviour

faas-cli is hardcoded to work with docker

Why do you need this?

Some background to show the strategic selection here... There are several reasons Podman may be selected over Docker

• totally open source/license friendly
• flexibility when it comes to defining VMs
• near 1:1 interface with docker cli
• supported by popular distros like minikube, kind

Who is this for?

Asking this as a personal inquiry, feature request for the community. I am not on the adopters list.

Which Solution Do You Recommend?

A command line flag to specify the driver

Steps to Reproduce (for bugs)

n/a

Context

Some moving away from Docker as they find other tools more appropriate for the use case. Tools that are hard-coded to use Docker will find that they lose OSS consumer base.

AFAIK I was unable to find this feature in the docs...
