KodeKloud exam lend


Hi, I'm a student currently preparing for the Certified Kubernetes Administrator exam, but I can't afford a KodeKloud subscription to access their mock exam series. I was wondering if anyone would be willing to lend me their KodeKloud account for a short time so I can practice with the mock exams and gauge my readiness. Your help would really mean a lot to me! Thanks in advance!

DevOps panic

I'm in my mid-twenties and work as a Junior SysAdmin/Technical Lead for a support team that specializes in niche Microsoft technologies. I started in the IT world less than three years ago and have been job-hopping every year for new challenges. I've taken a couple of courses, but that's it—no bachelor's degree or anything. I haven't even created a Kubernetes lab or opened up the interface.

Recently, I entered the interview process for a DevOps position at my company (a large firm that works with different clients around the world). At first, I didn't think my application would even be considered, but then, on Monday, out of the blue, I had a phone screening. The interviewer liked me, and that same night, he told me I’d have a more technical interview the next day.

I studied that night and the morning before the interview, but it was a lot to process in such a short time: Kubernetes, Git, methodologies, Docker, etc. Honestly, I thought I was going to show up and get humbled by my lack of experience (If any) in DevOps.

When Tuesday arrived, I was a bundle of nerves, not wanting to make a fool of myself. Somehow, I passed the interview, and they want another technical interview on Wednesday or Friday at most. They provided me with some topics to study for the client screening, and that's it.

Now, fear sets in as they told me there would be no peers to ask for help, no documentation, and no training or ramp-up. I would be on my own, and I need to create SOPs, manuals, guides, processes, and document everything to "pave the way for future peers."

One friend who works at a DevSecOps team told me that this is a really great opportunity, and he thinks i'll make it (Though he warned me that it will be a really difficult, soul crushing and just plain hard process until i get a grip on everything)

I'm really scared. What if I mess up and can't make the cut on my own? At the same time, I think this situation could force me to learn and move forward, but I'm just really fucking scared. But, who the fuck with no bachelors, less than three years of experience, and some cookie cutter certs would get a chance like this?

I want this, its a great chance to get a better life and a job I think i'll love, but im just scared of failure.

Any tips on how to study for the interview? This will be the hardest one. Sorry for the long text, its been crazy at least for me.

VSCode with cfn-lint and cfnnag on Windows

Can anyone give me a fairly decent step-by-step for installing cfn-lint and cfn\nag for use on Windows with VSCode and applicable extensions?


I found what appeared to be straight forward steps for using WSL to install both via Ubuntu, however the steps were outdated and did not work (from what I gather is due to recent Ubuntu security updates). From there I found numerous workarounds to get each to install, however then neither seemed to properly function with the appropriate extensions via Code.


At this point, given all the various things I had to attempt, I simply removed everything (VSCode extensions, installed packages, Ubuntu, and even WSL itself) and am starting fresh with hopes of getting something working fairly easily.


TIA for any advice you can provide. Appreciated.

How should I approach logging when loading testing?

I'm working on setting up a locust+prometheus+grafana stack for a client. Up until this moment I only wrote unit tests so I dealt with failed requests on a singular, manual basis. Thus I am unaccustomed to the scale of handling the potential failure of thousands and tens of thousands of requests. (i'm a fullstack dev repurposed into a devops).

I'd appreciate if you could answer a couple questions

1. How should I catch a failed request? Right now I am making event hooks in locust and logging the response body when debugging why a certain request fails. I have a feeling this isn't scaleable, yet I lack a clear path in thinking about a better solution.
2. Should I even try to "catch" or "debug" failed requests? I feel I am approaching load-testing from a bias of project development (i.e. print statements or unit tests) and maybe need some tweak in how I think about debugging when doing load testing and telemetry.
3. Should I persist in any shape or form the result of locust runs, or is it better delegated to a prometheus exporter which scrapes locust?
4. What should be the "shelf life" of the load tesing outputs (i.e. logs, performance data, failed request CSVs etc)? Should everything I produce live forever?
5. After I get a tool/service working with my clients environment, when do I begin autiomation? Devops has many tedious tasks (which is why almost everything is automated) but I want to avoid spending time on overengineering too soon.

How do you guys use PowerShell remoting ?

I have been working with PowerShell for more than 10 years. When it became open sourced and cross platform, I started to manage linux (and at home my macOs ) with PowerShell.

I was wondering how the devops community is using PowerShell remoting for remote management of machines.

If so, I think it can be interesting to discuss how and for what type of machines (and how many?) this is done. To keep things clear and short, maybe each can include the following data:

\- How many servers
\- Which type of machine (Windows / Linux / MacOs?)
\- Which protocol is used (OpenSSH / WinRM over HTTPS etc..)


\-----------

I'll go first:

\- Servers: 3000
\- Mostly Windows
\- WinRM over HTTP at first, then over HTTPS.

Details:

I have been managing mostly Windows machines (around 3000) with raw Powershell remoting. We went and got a licence of Ansible Tower, and this migrated on that platform for our configuration management system.

We use WinRM over HTTPS, as our machines are not always in our main active directory. Ansible is quite cool, but for Windows Management it still uses classical WinRM, and actually works great.

Since I was evaluating OpenSSH as an alternative (since Powershell supports that now) I actually took A LOT of notes. regarding POwerShell in general. I kept having the quesiton: Is PowerShell remoting actually secure ? (And a LOT of people would say it is not - for some obscure reason...)

I have summarized my notes and answer most of the general questions (how to configure, how does it work, is it secure etc....) in the following video -> https://www.youtube.com/watch?v=sg\_9r0PHnnM

Image Extraction Issue with WMF Format on Linux - Need Help Converting to PNG for OCR

Hi, everyone. I’ve built an app that processes PPT uploads by extracting text and images from the slides. The app also performs OCR on the images and saves them. It works perfectly on my development environment (Windows), but I hit a snag when I try to run it on an AWS Ubuntu instance. The issue is that when images are extracted from the PPT on Linux, they are in WMF format, and the system can't seem to work with these for further preprocessing (like OCR). This doesn't happen on Windows. I need to convert the extracted WMF images into PNG format before preprocessing, but I haven’t found a solid solution to handle WMF files on Linux. Has anyone dealt with this issue before? Any libraries or tools that could help with WMF to PNG conversion on Linux would be greatly appreciated! I appreciate any help you can provide.

Asking for advice

I'm computer science student, the job market in my country is hiring DevOps interns all the time for end of year internships, and I'm trying to get this opportunity since I'm really interested in a DevOps carrer. Can any of the Tech leads here, member of recruitment who is actively hiring DevOps engineers give me some advices on what makes someone a good candidate when it comes to DevOps.

I studied really hard for the last two years and I have good knowledge of DevOps practices and concepts. I've had so much hands on experience on different conepts (GitOps IaC Cloud) and technologies like Jenkins GitLab ArgoCD Ansible Terraform, also some CLI tools using Go and Python, projects on AWS GCP, and had some software engineering internships where I got the picture of how softwares are built and delivered.

I am really interested on what are the key skills that makes difference also the project you'd like to see in the resume.

I am ready to hear you feedback, also if possible I can share my resume with you so you can roast it.

Thank you 🙏🏻

Need help with Google Oauth 2 for Argo Workflows DEX authentication using Argo CD Dex

I went through the documentation that argo provides for adding dex authentication using the dex server that argo cd has, it was a bit weird with many fields in the current values yaml file in the helm chart not matching position or even name. I got google's oauth2 working on argo cd with dex using the default config provided in the values file for the helm chart. The problem is when adding the same dex auth method to argo workflows isn't as simple as argo workflows requires a service account so I followed the documentation to map a service account to a group, this requires reinstalling argo workflows so I did that then instead asking me to choose an account I get

# Access blocked: authorisation errorAccess blocked: authorisation error

Some requested scopes were invalid. {valid=[openid\], invalid=[groups\]} Learn more about this errorIf you are a developer of invite automation, see error details.Error 400: invalid_scope

does anyone here know how to implement argo cd dex authentication on the argo server used by argo workflows?

I wrote a piece on the evolution in the field of automation we're witnessing nowadays. I will be humbled to get the feedback on it and discuss the topic with the devops community.

hey!

some time ago a thought struck me: what if I started writing about my experiences from a day-to-day work as a data engineer? I have a knack for automating stuff so I genuinely wanted to focus on this topic.

I enjoy discussing with fellow thinkers about the topics of automation, technology, and artificial intelligence. I hope that showcasing my thought process and point of view via a longer text will allow people that find this interesting to reach out to me and/or provide some feedback, ideally to discuss the subjects I stir.

I've been recently thinking a lot about the progress we're witnessing in the field of generative AI, especially in a broader context of evolving automation—it's not just gears and gadgets anymore. I'm persuaded we're stepping into the third era of automation: intelligence, after automating physical labor and calculation. It's an exciting, inevitable, and challenging journey.

the link below will take you to the piece I've prepared to organize how I think about the automation evolution and how to find my way in the changing world (no LLM participated in the writing process :) )

🔗 https://toolongautomated.substack.com/p/automation-unbound

I dive into the following topics:

👉 the three eras of automation: physical labor, calculation, and intelligence.

👉 automation in our daily lives: whether we like it or not, automation is everywhere.

👉 lessons from history: what the past teaches us about adapting to a world increasingly shaped by machines.

I'd be humbled to hear your feedback on the piece, and hope to have some discussion about the subjects:

1. are you afraid and/or skeptical about progressing automation and AI?
2. do you enjoy discussing this subject or are you rather reluctant to do that?
3. if an artifact (a.k.a. indirect intelligence) is created by what I call direct intelligence (human) and that artifact appears to be a synthetic being, then should we call this artifact direct intelligence?

database devops schema changes

how do you guys do database schema changes in your team
your devops owns it or devs

are your schema changes tracked using flyway/other tool first in dev db and then same moved to prod

in ours prod db is separate and sql file changes are applied manually and no schema change due to db team review process,approvals in prod.
