I made a CLI game to learn Kubernetes by fixing broken clusters (50 levels, runs locally on kind)

Hey ,


I built this thing called K8sQuest because I was tired of paying for cloud sandboxes and wanted to practice debugging broken clusters.


## What it is


It's basically a game that intentionally breaks things in your local kind cluster and makes you fix them. 50 levels total, going from "why is this pod crashing" to "here's 9 broken things in a production scenario, good luck."


Runs entirely on Docker Desktop with kind. No cloud costs.


## How it works


1. Run ./play.sh - game starts, breaks something in k8s
2. Open another terminal and debug with kubectl
3. Fix it however you want
4. Run validate in the game to check
5. Get a debrief explaining what was wrong and why


The game Has hints, progress tracking, and step-by-step guides if you get stuck.


## What you'll debug


- World 1: CrashLoopBackOff, ImagePullBackOff, pending pods, labels, ports
- World 2: Deployments, HPA, liveness/readiness probes, rollbacks
- World 3: Services, DNS, Ingress, NetworkPolicies
- World 4: PVs, PVCs, StatefulSets, ConfigMaps, Secrets
- World 5: RBAC, SecurityContext, node scheduling, resource quotas


Level 50 is intentionally chaotic - multiple failures at once.


## Install


    git clone https://github.com/Aryan4266/k8squest.git
cd k8squest
./install.sh
./play.sh



Needs: Docker Desktop, kubectl, kind, python3


## Why I made this


Reading docs didn't really stick for me. I learn better when things are broken and I have to figure out why. This simulates the actual debugging you do in prod, but locally and with hints.


Also has safety guards so you can't accidentally nuke your whole cluster (learned that the hard way).


Feedback welcome. If it helps you learn, cool. If you find bugs or have ideas for more levels, let me know.

Docker's hardened images, just Bitnami panic marketing or useful?

Our team's been burned by vendor rug pulls before. Docker drops these hardened images right after Bitnami licensing drama. Feels suspicious.

Limited to Alpine/Debian only, CVE scanning still inconsistent between tools, and suppressed vulns worry me.

Anyone moving prod workloads to these? What's your take?

How do you integrate identity verification into CI/CD without slowing pipelines?

Hey folks, DevOps teams always need identity verification that plugs straight into pipelines without blocking deployments or creating security gaps since most solutions either slow everything down or leave staging environments exposed and we're looking for clean API handoffs delivering reliable signals at real scale.

Does anyone know of what works seamlessly for CI/CD flows?

I got tired of the GitHub runner scare, so I moved my CI/CD to a self-hosted Gitea runner.

With the recent uncertainty around GitHub runner pricing and data privacy, I finally moved my personal projects to a self-hosted Gitea instance running on Docker.

The biggest finding: Gitea Actions is compatible with existing GitHub Actions .yaml files. I didn't have to rewrite my pipelines; I just spun up a local runner container, pointed it to my Gitea instance, and the existing noscripts worked immediately.

It’s now running on my home server (Portainer) with $0 cost, zero cold-starts, and total data privacy.

Full walkthrough of the docker-compose setup and runner registration:https://youtu.be/-tCRlfaOMjM

Is anyone else running Gitea Actions for actual production workloads yet? Curious how it scales.

How do u know a CloudFormation CHANGE won’t break something subtle?

You change one resource.
The stack deploys successfully.
Nothing errors.

But something downstream breaks.

How do you catch that before deploy?
Or do you just accept the risk?

Curious how people think about this in practice.

Does anyone here use rapidapi? Having issues making a payment

I'm trying to add my card to purchase a subnoscription yet my card keeps declining. So then I decide to use klarna as a loan payback option and it gets declined. Then I use affirm for loan payback and the loan was charged but the payment was blocked by rapidapi. The only possible conclusion why this happened is I was making api calls from my laptop while using hotspot so I don't know if rapidapi considered this a proxy and decided to block me from making payments?

I built a browser extension for managing multiple AWS accounts

I wanted to share this browser extension I built a few days ago. I built it to solve my own problem while working with different clients’ AWS environments. My password manager was not very helpful, as it struggled to keep credentials organized in one place and quickly became messy.

So I decided to build a solution for myself, and I thought I would share it here in case others are dealing with a similar issue.

The extension is very simple and does the following:

Stores AWS accounts with nicknames and color coding
Displays a colored banner in the AWS console to identify the current account
Supports one click account switching
Provides keyboard shortcuts (Cmd or Ctrl + Shift + 1 to 5) for frequently used accounts
Allows importing accounts from CSV or `~/.aws/config`
Groups accounts by project or client

I have currently published it on the Firefox Store:
https://addons.mozilla.org/en-US/firefox/addon/aws-omniconsole/

The source code is also available on GitHub:

Is it just me or are some KodKloud course materials AI-generated?

Been using KodeKloud for a while now — love the hands-on labs and sandbox environments, they're genuinely useful for practical learning.

But I've started noticing some of the written course content has all the hallmarks of AI-generated text:

Forced analogies every other paragraph ("think of it like a VIP list...")
Formulaic transitions ("First things first," "Next up," "Time for a test run")
Repeated phrases/typos that suggest no human reviewed it ("violations and violations," "real-world world scenario")
Generic safety disclaimers at the end

Combined with other production issues I've noticed — choppy video edits, inconsistent audio quality, pixelated graphics, cropped screenshots cutting off text — it feels like they're prioritizing quantity over quality.

Anyone else noticing this? For what we pay, I'd expect better QA on the content. The practical stuff is solid but the courseware itself feels rushed.

EDIT: Typo in the noscript, oops, KodeKloud.

Artifactory nginx replacement

I am hosting Artifactory on EKS with nginx ingress controller for url rewrite. Since nginx ingress controller will be retired, what to use instead? First though is to use ALB because it now supports url rewrite. Any other options?

Please let me know your opinions and experience.

Thank you.

Stuck on the Java 8 / Spring Boot 2 upgrade. Do you need a "Map" or a "Driver"?

We are currently debating how to handle a massive legacy migration (Java/Spring) that has been postponing for years. The team is paralyzed because nobody knows the blast radius or the exact effort involved.

We are trying to validate what would actually unblock teams in this situation.

The Hypothetical Solution:
Imagine a "Risk Intelligence Service" where you grant read-access to the repo, and you get back a comprehensive Upgrade Strategy Report.
It identifies exactly what breaks, where the test gaps are, and provides a step-by-step migration plan (e.g., "Fix these 3 libs first, then upgrade module X").

My question to Engineering Managers / Tech Leads:
If you had budget ($3k-$10k range) to solve this headache, which option would you actually buy?
- Option A (The Map): "Just give us the deep-dive analysis and the plan. We have the devs, we just need to know exactly what to do so we don't waste weeks on research."
- Option B (The Driver): "I don't want a report. I want you to come in, do the grunt work (refactoring/upgrading), and hand me a clean PR."
- Option C (Status Quo): "We wouldn't pay for either. We just accept the pain and do it manually in-house."

Trying to figure out if the bottleneck is knowledge (risk assessment) or capacity (doing the work).

The cognitive overhead of cloud infra choices feels under-discussed


Curious how people here think about this from an ops perspective.

We started on AWS (like most teams), and functionally it does everything we need. That said, once you move past basic usage, the combination of IAM complexity, cost attribution, and compliance-related questions adds a non-trivial amount of cognitive overhead. For context, our requirements are fairly standard: VMs, networking, backups, and some basic automation,,, nothing particularly exotic.

Because we’re EU-focused, I’ve been benchmarking a few non-hyperscaler setups in parallel, mostly as a sanity check to understand tradeoffs rather than as a migration plan. One of the environments I tested was a Swiss-based IaaS (Xelon), primarily to look at API completeness, snapshot semantics, and what day-2 operations actually feel like compared to AWS.

The experience was mixed in predictable ways: fewer abstractions and less surface area, but also a smaller ecosystem and less polish overall. It did, however, make it easier to reason about certain operational behaviors.

Idk what the “right” long-term answer is, but I’m interested in how others approach this in practice: Do you default to hyperscalers until scale demands otherwise, or do you intentionally optimize for simplicity earlier on?

How did you get into DevOps and what actually mattered early on?

I’m learning DevOps right now and trying to be smart about where I spend my time.

For people already working in DevOps:

- What actually helped you get your first role?

- What did you stress about early on that didn’t really matter later?

- When did you personally feel “ready” for a job versus just learning tools?

One thing I keep thinking about is commands. I understand concepts pretty well, but I don’t always remember exact syntax. In real work, do you mostly rely on memory, or is it normal to lean on docs, old noscripts, and Google as long as you understand what you’re doing?
I’m more interested in real experiences than generic advice. Would love to hear how it was for you.

Reflections on DevOps over the past year

This is more of a thinking-out-loud post than a hot take.

Looking back over the past year, I can’t shake the feeling that DevOps has gotten both more powerful and more fragile at the same time.

We have better tooling than ever:
- managed services everywhere
- more automation
- more abstraction
- AI creeping into workflows
- dashboards, alerts, pipelines for everything

And yet… a lot of the incidents I’ve seen still come down to the same old things.

Misconfigurations (still rampant at my company).
Shared failure domains that nobody realized were shared.
Deployments that technically “worked” but took the system down anyway (thinking of the AWS one specifically)
Observability that only told us what happened after users noticed.

It feels like we keep adding layers on top of systems without always revisiting the fundamentals underneath them.

I’ve been part of incidents where:
- redundancy existed on paper, but not in reality
- CI/CD pipelines became a bigger risk than the code changes themselves (felt this personally since our team took control of the cloud pipelines at my company)
- costs exploded quietly until someone finally asked “why is this so expensive?”
- security issues weren’t exotic attacks — just permissions that were too broad

None of this is new. But it feels more frequent, or at least more visible.

I’m genuinely curious how others see it:
- Do you feel like the DevOps role is shifting?
- Are we actually solving different problems now, or just re-solving the same ones with new tools?
- Has the push toward speed and abstraction made things easier… or just harder to reason about?

Not looking for definitive answers — just interested in how others experienced this past year.

How do you track your LLM/API costs per user?

Building a SaaS with multiple LLMs (OpenAI, Anthropic, Mistral) + various APIs (Supabase, etc).

My problem: I have zero visibility on costs.

* How much does each user cost me?
* Which feature burns the most tokens?
* When should I rate-limit a user?

Right now I'm basically flying blind until the invoice hits.

Tried looking at Helicone/LangFuse but not sure I want a proxy sitting between me and my LLM calls.

How do you guys handle this? Any simple solutions?

I have been working on a self-hosted GitHub Actions runner orchestrator

Hey folks,

I have been working on CIHub, an open-source project that lets you run self-hosted GitHub Actions runner on your own metal servers using firecracker. Each job runs in its own isolated VM for better security.

It integrates directly with standard GitHub Actions workflows allowing you to specify runner resources (e.g. adding label runs-on: cihub-2cpu-4gb-amd64) and includes a server + agent setup for scaling across machines.

The project is still early and under active development, and I'd really appreciate any feedback or ideas !
