Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

I use podman because it's more secure. I'm willing to put in the extra effort so that all my services aren't running as root. If it turns out a vulnerability is discovered in lemmy tomorrow that allows people to access my server through my lemmy container, the attacker will only have access to a dummy account that hosts my containers. Yes, they could stop all my containers, but they can't delete the volumes or any other data on my server.
Don't let perfection be the enemy of good. Security is not all or nothing. Reducing the attack surface is still important.
Can you elaborate on running docker daemon as rootless? It's my understanding that you can add your account to a group to access the docker daemon rootless, but the containers are still running as root, as the daemon itself raises the access to root.
No. The daemon can run without root, as such the containers don't have root. My docker install doesn't have root access. None of my stacks / containers need any root access tbh. I don't have any troubles with deplyong stuff.

I never said I was relying on it alone. Not sure why you think that.
That's a great link. Thank you for sharing. It's good that docker supports this functionality now.
I think you're interpreting too much. Security is about layers and making it harder for attackers, and that's exactly what using a non-root user does.
In that scenario, the attacker needs to find and exploit another vulnerability to gain root access, which takes time - time which the attacker might not be willing to spend and time which you can use to respond.
Funny how you claim to know so much about security but can't even seem to comprehend my comment. I know root shell exploits exist, that's why I wrote that it takes additional time to get root access, not that it's impossible. And that's still a security improvement because it's an additional hurdle for the adversary.
the person you are replying to either lacks comprehension or maybe just wants to be argumentative and doesn't want to comprehend.
Once again, you're going off on an unrelated tangent. If you don't want to listen, I can't help you. We're done here.
