Support for podman

[hans-lammda]

Ubuntu supports a CLI emulation of docker apt install podman-docker

There is some minor issues with missing directories that must be fixed

Build-directory product/build

The alpine repository is cloned, and cached. The default dir is /tmp/alpine. The following dirs must be created.

mkdir -p /tmp/alpine/src mkdir -p /tmp/alpine/checkout mkdir -p /tmp/alpine/cache
