If you would like to use Docker as a non-root user, you should now consider
adding your user to the “docker” group with something like:

sudo usermod -aG docker vyos

Remember that you will have to log out and back in for this to take effect!

WARNING: Adding a user to the “docker” group will grant the ability to run
containers which can be used to obtain root privileges on the
docker host.
Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
for more information.

Welcome to the Vyos forums.

Vyos isn’t a standard Debian system. It’s highly customised and has a different filesystem to allow the in place image upgrades.

There has been mention of getting docker or some form of containerisation working under Vyos, I’m not sure how much (if any) progress has been made on it.

But what you’re seeing isn’t surprising - you’re not really on a standard Debian system.
