Adapt `local_check_linux()` to run with docker alternative like `podman` ?

[cderv]

I tried podman which is an alternative for docker, and from doc it was supposed to be a 1-1 equivalent mainly , meaning something that run with docker runs with podman

https://developers.redhat.com/blog/2019/02/21/podman-and-buildah-for-docker-users

I did a quick test:

• I add this in rhub-linux.sh (by modifying my local install of rhub)

  docker() {
  /usr/bin/podman "$@"
  }

• then I ran rhub::local_check_linux(image = "rhub/debian-gcc-devel")

Everything worked as expected, (except running manually the image at the end because it seems that podman does not use name but only id).

Anyway, having a way to configure a docker alternative would be great to benefit from this feature of running local checks in container.

Just throwing the idea for this, either for support or just a switch that could allow advanced at your own risk usage.

This issue is about the previous R-hub system, it does not apply to the new system, so I am closing it now. Please see https://r-hub.github.io/rhub/ for the new system, R-hub v2.
