overlayfs-podman-ubuntu

Shell scripts to set up Podman container runtine, crun, and OverlayFS in Ubuntu. Podman containers run faster and safer when powered by overlayfs and crun.

These scripts are intended to set up rootless Podman (most popular way to use it) and run in a fresh Ubuntu environment. Ubuntu >= 20.04 is required due to cgroup v2 support.

Environment setup

chmod +x set-up-system.sh set-up-current-user.sh

Set up crun, fuse-overlayfs, and podman

sudo ./set-up-system.sh

./set-up-current-user.sh

Expected results
