Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Swag reverse proxy, fail2ban not working
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.

Docker Overrules UFW
[2016]
A solution is known and formed detailed here: https://github.com/chaifeng/ufw-docker
- DHCP is not blocked by ufw/iptables

Docker networking seems to have completely broken, can't really explain it all in the title.
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

Security on ubuntu
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.

Gluetun/QBitTorrent Web UI issues
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.

What OS for NUC with Plex, Arrs, Home Assistant & Frigate
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)

Why Use Make
Hm yes now I remember that point about how the data is anonymous Python objects that you can pass around to functions.
Are there any open source examples? I looked around the github account, but I mostly remember this tool
https://github.com/stb-tester/apt2ostree
I'd be interested in seeing the Python config and Ninja output, to see how it works. Right now it looks to me like the dependencies are more implicit than explicit, e.g. with your copen example
---
The system I ended up with is more like Bazel, but it's not building containers, so it's a slightly different problem. But I'm interested in building containers incrementally without 'docker build'.
I like the apt lockfile idea definitely ... However I also have a bunch of other blobs and tarballs, that I might not want to check into git. I guess you just put those in OSTree?
Our config looks like this
https://github.com/oilshell/oil/blob/master/core/NINJA_subgr...
And all the code is in build/ninja* of the same repo

An ode to Flatpak (and Fedora Silverblue)

Docker containers usually still reachable even if bound to 127.0.0.1
With apt2ostree[1] we use lockfiles to allow us to version control the exact versions that were used to build a container. This makes updating the versions explicit and controlled, and building the containers functionally reproducible - albeit not byte-for-byte reproducible.

Any plans for an immutable Debian desktop?
If you have time to test things, you can try to use ostree to manage a Debian installation. This is what Silverblue uses. Their is already a tool to create APT-based ostree images.

Reproducible builds for Debian: a big step forward
On the subject of reproducible debian-based environments I wrote apt2ostree[1]. It applies the cargo/npm lockfile idea to debian rootfs images. From a list of packages we perform dependency resolution and generate a "lockfile" that contains the complete list of all packages, their versions and their SHAs. You can commit this lockfile to git.
You can then install Debian or Ubuntu into a chroot just based on this lockfile and end up with a functionally reproducible result. It won't be completely byte identical as your SSH keys, machine-id, etc. will be different between installations, but you'll always end up with the same packages and package versions installed for a given lockfile.
This has saved us on a few occasions where an apt upgrade had broken the workflow of some of our customers. We could see exactly which package versions changed in git history and roll-back the problematic package before working on fixing it properly. This is vastly better than the traditional `RUN apt-get install -y blah blah` you see in `Dockerfile`s.
IMO it's also more convenient than debootstrap as you don't need to worry about gpg keys, etc. when building the image. Dependency resolution and gpg key stuff is done at lockfile generation time, so the installation process can be much simpler. In theory it could be made such that only dpkg is required to do the install, rather than the whole of apt, but that's by-the-by.
apt2ostree itself is probably not interesting to most people as it depends on ostree and ninja but I think the lockfile concept as applied to debian repos could be of much broader interest.
