nestybox is an alternative runc instead of the default containerd which is more hardened, efficient and secure.  It even allows you to do a lot of things you normally couldn't without having privileged mode which is great for development and many other functions.

However, the only drawback is that you must not have any docker containers already, if so you have to back them up / delete them before proceeding.

Step 1.) Get the latest .deb / package:

wget https://downloads.nestybox.com/sysbox/releases/v0.6.7/sysbox-ce_0.6.7-0.linux_amd64.deb

sysbox github https://github.com/nestybox/sysbox

Step 2.) Install required packages

apt install rsync jq

Step 3.) Install package

dpkg -i sysbox-ce_0.6.7-0.linux_amd64.deb

Step 4.) How to use it:

docker run --runtime=sysbox-runc ubuntu:20.04
