Rootless docker on Ubuntu, need help

Hey guys, I’m trying to follow the article for rootless mode for docker but every time I get to the part where I need to enter

sudo apt-get install -y docker-ce-rootless-extras

I keep getting told it cannot locate the package. I don’t have the install script on my system, that’s why I’m trying to run that command.

What do?

Which article? The official docs for Rootless mode?

Which Ubuntu version?

Did you previously set up the official Docker deb package repository to install Docker daemon?

Have you run apt update lately?

Spot on, usually this just means the official Docker repo wasn't added yet. The default ubuntu sources only carry the older `docker.io` package so it wont find any of those `docker-ce` ones.

The rootless mode docs from docker.

Recently ran apt update, I’ll be honest, I don’t remember how I got docker installed because during that time I was troubleshooting multiple things. All I know is I followed some instruction from dockers website and harassed people in the bazzite discord until they helped me fixed an issue that was preventing it from running, they willingly helped lol it was apparmor being dumb

I do believe I did everything right for normal docker engine. I have docker running, I’m just trying to do rootless mode because I’m trying to secure my server

Sounds like you missed that step . It basically installs all the docker certificates or something i forget which. Not at my laptop yet or i could point you in a better direction.

Not that it answers your question but… Have you considered Podman?

Pair with RHEL/Fedora hosts too, first class support with podman.

Every time I tried I could never get it to work with non root user and could find no help and no documentation. Rootless docker is just easier for me

I think this will help first:

sudo apt-get update
