Thank you podman! Well, I saw a rather dramatic increase on disk usage when running podman rootless. Looked like podman did a full container image copy for each docker file step instead of properly stacking incremental changes. Didn't investigate why. Therefore my "docker" looks like this: kraxel@sirius ~# cat bin/docker #!/bin/sh proxy=3D"https_proxy,http_proxy,ftp_proxy,no_proxy" exec /usr/bin/sudo --preserve-env=3D"${proxy}" /usr/bin/podman "$@" So, yes, podman can run our docker tests just fine, but the rootless mode has some hickups still. cheers, Gerd
