[v3,4/6] ci: refactor docker runner script

Commit Message

Đoàn Trần Công Danh April 2, 2020, 1:04 p.m. UTC

We will support alpine check in docker later in this series.

While we're at it, tell people to run as root in podman,
if podman is used as drop-in replacement for docker,
because podman will map host-user to container's root,
therefore, mapping their permission.
