To install Docker on Debian as root:

  1) apt-get update
  2) apt-get install ca-certificates curl gnupg lsb-release
  3) curl -fsSL https://download.docker.com/linux/debian/gpg | gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
  4) echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian \
     $(lsb_release -cs) stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null
  5) apt-get update
  6) apt-get install docker-ce docker-ce-cli containerd.io

To enable Docker in an unprivileged LXC container:

  1) run: nano /etc/pve/local/lxc/<container id>.conf
  2) add "features:  keyctl=1,nesting=1" to the file
  3) save, exit
  3) reboot the container

To test Docker with NetData:

  docker run -d --name=netdata -p 19999:19999 -v netdataconfig:/etc/netdata -v netdatalib:/var/lib/netdata -v netdatacache:/var/cache/netdata -v /etc/passwd:/host/etc/passwd:ro -v /etc/group:/host/etc/group:ro -v /proc:/host/proc:ro -v /sys:/host/sys:ro -v /etc/os-release:/host/etc/os-release:ro --restart unless-stopped --cap-add SYS_PTRACE --security-opt apparmor=unconfined netdata/netdata

Hello!
Sorry, what is the goal for this?
On ProxMox I have created a standard VM with Ubuntu, installed docker and as per I can see it works fine! :-)
Also, the folder /etc/pve/local/lxc/ is empty on my ProxMox, if I am taking a look at the correct place....
Regards,

Sorry, what is the goal for this?

The goal is to create an LXC container which can run Docker containers. LXC containers share the host kernel, typically use less cpu/ram than virtual machines, and are preferred by some when running docker containers under Proxmox.

Also, the folder /etc/pve/local/lxc/ is empty on my ProxMox

This is simply because you haven't yet created any LXC containers.

Thanks for the clarification!
