ufw-docker VS podman

I am running ubuntu server 22.04 LTS and have fail2ban running on the host. This works great, no issues and IPs get banned for the rules I have in place. I am using UFW and have updated my after.rules for docker based on the recommendations here.

I use this without problems for Long time, https://github.com/chaifeng/ufw-docker

A solution is known and formed detailed here: https://github.com/chaifeng/ufw-docker

In any case, maybe try to compare the blocked port ranges with the ports you are using. Did you see this https://github.com/chaifeng/ufw-docker

https://github.com/chaifeng/ufw-docker For example.

ufw is nice, when you are on public networks. And very nice if you are playing with SSH-Server, Docker,.. on your notebook. Couse you write coding, I want to add this, if you use docker.

You can use use this for a more manual approach: https://github.com/chaifeng/ufw-docker

Sorry that's about the extent of my docker network knowledge. One other thing you can check though - are you running ufw on the host? If so you can try updating the config with ufw-docker.

Hi! I'm also new to the homelab category, but I have a bit of experience. I'm currently running Ubuntu 22.04, and the only problem what I had is docker containers not working with ufw. (Fix can be found here: https://github.com/chaifeng/ufw-docker) I've been running my stuff in Docker containers, and it worked pretty well for me. So if you are also new to this, I'd definetly recommend Ubuntu for its simplicity. (Also tons of already great tutorials on how to do literally anything)

Podman

Even though we will focus on Docker for this article, I wanted to mention that there are more container creation and management tools such as Podman, Rkt, and so on.

By using containerization, the application will always have the same configuration that is used in the development environment and production environment. There is no more "It works on my machine". Some examples of containerization technologies are Docker and Podman.

Podman Documentation. Podman is a daemonless container engine for developing, managing, and running OCI Containers on your Linux System.

AFAIK podman either already supports pods in quadlet container files, or will in the near future. https://github.com/containers/podman/pull/20762

Podman as a devcontainers engine doesn't currently work if you use devcontainer features [1] or (and this sounds like you're issue) if you use WSL2.

I haven't submitted the WSL2 issue to the Podman team yet. If you get to it before I do, can you like it here?

You can also use their Oracle Linux Docker images with the database preinstalled using either Podman or Docker. Just make absolutely sure you are downloading something you are licensed to use, because it seems really easy to accidentally infringe copyright via this method.

It's an open source project. https://github.com/containers/podman and https://podman.io - go there, get engaged, see what's going on and most important become part of the community and contribute!
