cli VS kubernetes

GitHub CLI - GitHub on the command line. Great for creating PRs, etc.

This package is widely used for powerful CLI builds, it is used for example for Kubernetes CLI and GitHub CLI, in addition to offering some cool features such as automatic completion of shell, automatic recognition of flags (the tags) , and you can use -h or -help for example, among other facilities.

This Docker image is designed to support implementing Github Actions with Python. As of version 4.0.0., it starts with the official python docker image as the base which is a Debian OS. It specifically uses python:3-slim to keep the image size down for faster loading of Github Actions that use pyaction. On top of the base, we've installed curl gpg, git, and the GitHub CLI. We added curl and gpg because they are needed to install the GitHub CLI, and they may come in handy anyway (especially curl) when implementing a GitHub Action.

You might be interested in GitHub's cli tool, which is open source, if you want to access GitHub without running their proprietary JS code.

(Context: I'm pretty thick into Nix, and have been for about four years. Most of this post is focussed on the NixOS desktop experience, so DevOps nerds, ymmv.)

Unpopular opinion: Nix is not that hard.

What's "hard" from a nix-promotion strategy is motivating people to understand why they would want the benefits it offers. Mostly because Nix, especially with home-manager, dramatically worsens UX for several day-to-day tasks, simply by violating the Law of Least Surprise every couple of hours in normal use.

I want a fully idempotent, version-locked, rewindable user environment, with a version-controlled central config, because I have half a dozen devices that, for reasons, I need to keep perfectly interchangeable with one another. Most users do not want this, for the simple fact that mutating their configs and differentiating them locally on specific machines is not a bug, but a feature.

Even more than that, it's an expectation that most software developers share as well.

Case in point: I filed a bug against the GitHub CLI last week. If any org has the scope and motivation to build software that's compatible with NixOS, an OS most of whose users are developers, it should be GitHub, which is, at least notionally, all about developers, developers, developers. A change in GH required a config format migration, which was sensibly done by opening the config .yml and rewriting it.

Of course, this breaks NixOS not just in practice but in principle. NixOS/home-manager makes config files read-only. Surprise! https://github.com/cli/cli/issues/8462

The response from GitHub was basically, "yeah, we knew this was going to happen, we mentioned it to the packagers at NixOS, but we did it anyway, because it was still the best way to proceed for us." (And they weren't wrong.)

Now, once a month is an annoyance, but I run into these problems daily. I can't imagine any sane person -- which I am not -- would persist with using it.

Why do I keep using NixOS, then? Because I am terribly and disproprotionately annoyed by small changes in my user experience, which I find disruptive to my workflow and hence threaten my success. For me, forbidding apps from mutating the config files I established for them is a selling point. Being able to version-control an idempotent declarative config for all of them at once is heaven.

Unless you're like me, you'll hate NixOS. But some were meant for Nix.

Because

To use a proper dynamic auth for ghcr.io you can create a "credential helper" and then it is supported by flux, see here: https://fluxcd.io/flux/cheatsheets/oci-artifacts/#authentication Unfortunately the "official" credential helper for ghcr.io doesn't exist. I use this simple script as a helper: https://gist.github.com/pkit/a98411d21ecc9293066f4579088187d1 Which requires gh cli to be installed.

Two CLI tools I install right away are the GitHub CLI (via brew) and the Netlify CLI (via npm).

Recently, I’ve spent some time playing around with Kubernetes (K8s). Having never used it before, I gave it my humble first try. I used it as part of a project where I wanted to use self host some tools on a VPS and write some server code for some life automations and potentially a blog in the future. You can find the Github Repo for the project at the time of writing for it here.

Kubernetes - An open-source system for automating deployment, scaling, and management of containerized applications. Kubernetes Documentation - Official documentation.

A manufacturing company might leverage a combination of Kafka for real-time data streaming, Kubernetes for container orchestration, and dbt for data transformations. They could use Dataplex for unified data management and security across domains. This technology stack would enable the Production Data team to monitor and analyze production metrics in real-time, the Supply Chain Data team to manage and optimize logistics and inventory, and the Quality Control Data team to ensure product compliance and quality. By investing in these tools, the company can effectively support the decentralized data management and governance principles of Data Mesh.

The best method to counter these problems is CloudNativePG operator, this operator manages PostgreSQL workloads on any supported Kubernetes cluster.

Stacklok was founded in 2023 by Craig McLuckie (co-creator of Kubernetes) and Luke Hinds (creator of the OpenSSF project Sigstore), with the goal of helping developers produce and consume open source software more safely.

Kubernetes, an open-source platform for automating the deployment, scaling, and operation of application containers, has become a fundamental tool for modern software development. Here are some of the top Kubernetes commands every developer should know, along with comments explaining their usage:

Orchestration with Kubernetes is simple to set up, but there are some challenges to managing resource usage in a cost effective way.

Said audience member here. "The Kubernetes project" includes a bit more than just https://github.com/kubernetes/kubernetes, but yes that's accurate.

Here's our GCP spend for the past month: https://imgur.com/a/VVJTSKx. Note that does not include a separate AWS cluster that we are migrating jobs too.

A large chunk of this comes from the nature of distributed tests. We need to reproduce the environment, spin up compute, etc. We do have a large problem with flaky tests on the project as well. Whether that's timeouts, memory/cpu consumption creep over time, loads of other things. We talk about how one day we'd like to get to the granulairty of being able to go to a SIG and say, "this flaky test of yours is costing the project $x in retries. Please dedicate some resources to fix it".

How we distribute the artifacts is a whole different conversation. The container world is unique in that voluntary mirrors are not as possible as with linux packages and other binaries.
