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.

Show HN: Bocker-compose, the missing layer to Docker-compose
A (joke?) one-liner I came up with while thinking about solutions to centralized container management across multiple SSH hosts. Shame on me.
The name is inspired by bocker [0], albeit this doesn't re-implement docker-compose in bash, I found it to be fitting enough.
I'd love to see someone come up with a smarter and/or shorter way to do this.

Barco: Linux Containers from Scratch in C
When I did a talk about docker I also wanted to show a bit of what it does under the hood without going through all the layers and without too much details. This ~120 lines of shell script is really good in providing just an intro into what's needed for containers: https://github.com/p8952/bocker/blob/master/bocker

Latest Zen Kernel......
i tried it and like the concnpt, but until it can be launched via a systemd userspace service (without previously manually booting it) among other problems i will keep using docker (or bocker)

The Staff Engineer's Path – Book Review
> But you couldn't reimplement podman in a few hundred lines of code.
You don't even need a few hundred: https://github.com/p8952/bocker
And then there's 'dokku' which IIRC, started as a bash version of Heroku.
> Not all ideas have the same quality.
They really do. I've heard all kinds of things in my career, but almost none I would want to dedicate a portion of my life building. Not because they are bad ideas or won't work, but because of the person with the idea or it just didn't interest me. Those people went on to be moderately successful (like hundreds of millions worth) but I'm glad I wasn't on that ride.

“Implement DNS in a Weekend”
Bocker is in this same category...docker clone in bash that's helpful in seeing what's really happening underneath with nsenter, namespaces, network bridging, cgroups, etc.

Ask HN: What is the best source to learn Docker in 2023?
Docker implemented in around 100 lines of bash: https://github.com/p8952/bocker
This is the most mindblowing example for enterprise security teams that think Docker is a new threat on a single tenant Linux host.
No, buddies, all this stuff is already there. If you were fine with your visibility before*, you're still fine. Go find a real problem while we play with our developer dopamine.
* NARRATOR: They shouldn't have been.

Containers are chroot with a Marketing Budget
Bocker[1] does a reasonably good job of showing the value of Docker was mostly in Docker hub.
[1] https://github.com/p8952/bocker
There is a cool project I've seen called "bocker" (https://github.com/p8952/bocker) which is something of a proof of concept of implementing Docker with bash, which speaks a bit to how Docker is indeed in many ways an amalgam of lower level primitives (such as chroot as you mentioned). Pretty neat!

Ask HN: Are there any open source forks of nomad smd consul?
Opinionated meaning it picks, install, patches your CNI/Ingress/Load Balancer/DNS Server/Metrics Server/Monitoring Setup.
k3s is probably most well known as it ships with bunch of preinstall software: https://github.com/k3s-io/k3s so you can just start throwing yaml files at cluster and handling workloads. It's what I use for my homelab.
Paid things I've heard of include OpenStack and SideroLabs. Haven't used personally by SRE coworkers say good things about them.

Linux fu: getting started with systemd
For self-hosting I've found https://k3s.io to be really good from the SUSE people. Works on basically any Linux distro and makes self-hosting k8s not miserable.

Nix is a better Docker image builder than Docker's image builder
Yes it’s going to depend on which k8s distribution you’re using. We have work in-progress for k3s to natively support nix-snapshotter: https://github.com/k3s-io/k3s/pull/9319
For other distributions, nix-snapshotter works with official containerd releases so it’s just a matter of toml configuration and a systemd unit for nix-snapshotter.
We run Kubernetes outside of NixOS, but yes the NixOS modules provided by the nix-snapshotter certainly make it simple.

K3s Traefik Ingress - configured for your homelab!
I recently purchased a used Lenovo M900 Think Centre (i7 with 32GB RAM) from eBay to expand my mini-homelab, which was just a single Synology DS218+ plugged into my ISP's router (yuck!). Since I've been spending a big chunk of time at work playing around with Kubernetes, I figured that I'd put my skills to the test and run a k3s node on the new server. While I was familiar with k3s before starting this project, I'd never actually run it before, opting for tools like kind (and minikube before that) to run small test clusters for my local development work.

Building a no-code Helm UI with Windmill - Part 1
I’ve created a local cluster with K3S and installing Windmill could not be simpler with just one chart to configure, which already has sane defaults to get started. For this demo we will also configure workers to passthrough environment variables to our scripts so that they have access to the Kubernetes API server for later.

Highly scalable Minecraft cluster
You should be familiar with Kubernetes and have set up a Kubernetes cluster. I recommend k3s.
What are some alternatives?
whalebrew - Homebrew, but with Docker images
k0s - k0s - The Zero Friction Kubernetes
s6-overlay - s6 overlay for containers (includes execline, s6-linux-utils & a custom init)
kubespray - Deploy a Production Ready Kubernetes Cluster
garden - Automation for Kubernetes development and testing. Spin up production-like environments for development, testing, and CI on demand. Use the same configuration and workflows at every step of the process. Speed up your builds and test runs via shared result caching
Nomad - Nomad is an easy-to-use, flexible, and performant workload orchestrator that can deploy a mix of microservice, batch, containerized, and non-containerized applications. Nomad is easy to operate and scale and has native Consul and Vault integrations.
distroless - 🥑 Language focused docker images, minus the operating system.
microk8s - MicroK8s is a small, fast, single-package Kubernetes for datacenters and the edge.
dockerfiles - Various Dockerfiles I use on the desktop and on servers.
Docker Compose - Define and run multi-container applications with Docker
cloc - cloc counts blank lines, comment lines, and physical lines of source code in many programming languages.
