It took me 20 years

I finally got a job building infrastructure as code. AWS Code Pipeline + Terraform, with a promise to also get hands on with Azure and their devops/pipeline products. I have a chronic health condition that really slowed me down. Miraculously, I found a way to manage it better and my health has started improving. My wife is a rock, she stayed by my side. Today was a good day, and for the first time in a very long time I can see a kind of light at the end of the tunnel, or at least, some sunshine. Some good days ahead, decent health, a decent income, a future while I still have some life left in me to make good use of it.

Onwards

Edit: now that I think about it, I first picked up Linux RedHat 4, that's RHL not RHEL, I paid for an actual CD. I think that was in the late 1990s 1996-1998 so I guess I could say really I started down this path over a quarter of a century ago

Need some roasting on my resume

Hey I am really stuck at this point in my career, need some serious advices, also FYI my actual experience as a DevOps engineer would be 8 months as the rest of the months went in as a trainee. This was my first job as a fresher and I feel like i may lack in the development experience. the current company doesn't have that great pf a devops culture, a few project here and there come that have some decent tasks for me, recently they've started to focus a lot on making projects for aws market place so maybe I'll get some more work to do, but overall not at all satisfied with my growth here,so need some honest suggestions.

Best networking architecture for production Kubernetes cluster? (NAT vs direct, HA design)

I'm designing my first production K8s cluster using Kubespray, and I'm unsure about the networking architecture. I'm thinking of 3 masters and 2+ workers, but should I use NAT or direct exposure? Would an HA proxy that's only in the public network but shares a private network with the cluster be a good approach? What's your production network topology?

Any guidance, diagrams, or resources would be greatly appreciated!

Stateful workloads in K8s production: Longhorn vs external solutions?

I'm planning a production Kubernetes cluster and deciding whether to run stateful applications on it. I'm considering Longhorn for storage, but I'm not sure if keeping databases inside vs outside the cluster is better for production.

For those using Longhorn in production: how's your experience? Any gotchas or configuration advice? And in general, what's your approach to stateful workloads in production Kubernetes?

K8s capacity planning tools & methods for new production cluster?

I'm about to deploy a production Kubernetes cluster using Kubespray and I'm trying to figure out how to properly size it. Are there any standard tools or calculators to estimate required resources?

How do you approach node sizing when workload details aren't fully known yet? Any rules of thumb for CPU/memory/storage ratios? Would love to hear about your capacity planning experiences and mistakes to avoid.

GitHub Actions Development

A lot of my work lately has been around developing better workflows for my team. This involves creating new or improving our existing GitHub Actions. The development process can be such a pain. The actions require so much context that testing locally feels like more work than it’s worth so I end up doing a bunch of pr → merge → observe → adjust cycles to get it into a working state. Anyone have any pointers for making this process more efficient?

Why no building blocks for ci/cd?

Heya

Somehow everywhere I have worked, so far with github, gitlab, jenkins, bitbucket and azure, the main bits in a ci/cd pipeline were:

- (merge requests were luckily mostly painless)
- check out one or more git repositories
- build artifact
- run tests
- push artifact to some registry
- tag git commit for releases
- push artifact to some environment

and every time I see hundreds or thousands of lines of shell, groovy, javascript, python, powershell etc, all home grown, to achieve the same goals again and again.

What am I missing?

Is My Kubernetes Self-Healing & Security Project a Good Fit for a Computer Engineering Graduation Project?

Hey r/devops & r/kubernetes,

I'm a computer engineering student working on my graduation project (PFE), and I’d love to get some feedback on whether my project idea is solid and valuable.

Project Idea:

I’m building a self-healing Kubernetes infrastructure with enhanced security and observability, optimized for a telecom environment (Tunisie Telecom). The goal is to create a fully open-source solution that integrates:

✅ Self-Healing: Using Horizontal Pod Autoscaler (HPA), Node Problem Detector, and potentially a custom self-healing script based on logs.
✅ Security Enhancements: Open Policy Agent (OPA) for policy enforcement, Falco for runtime security monitoring, and Kubernetes RBAC & Network Policies.
✅ Advanced Observability: Prometheus + Grafana for monitoring, plus Fluentd or Loki for logging.
✅ Automation & Resilience: Possibly implementing a Kubernetes Operator or a CI/CD pipeline for auto-recovery.

Why This Project?

Self-healing Kubernetes is crucial for minimizing downtime.

Security is a major concern, especially in telecom environments.

Many DevOps teams struggle with observability, so integrating metrics/logs is valuable.

It’s a hands-on project with real-world applications.


My Questions:

1. Do you think this is a strong project for a computer engineering graduation project?


2. What improvements or additions would make it stand out even more?


3. Is there any recent open-source tool that I should consider integrating?



Would love to hear your thoughts—any feedback is greatly appreciated!

Any NZ devops here? 20+ years sysadmin/devops guy thinking of relocating from NL to NZ

Hey everyone,

As the title says. I'm a 20+ years of experience devops/sysadmin guy thinking of relocating my family from NL to NZ, we're both working in programming and we have a 2 year old daughter.

I've been working as a freelancer the past 4 years, but I'm not sure what the market would be there for freelancer devs.

Does anyone have any tips for people looking to relocate? I imagine the dev market is also down there as everywhere right now..

Which courses to take for CKA?

It seems certification questions are banned in the k8s subreddit. Sorry to the people who are annoyed by these questions.

For those who takes Mumshad Mannambeth courses for CKA recently, first of all would you recommend Kodecloud or Udemy?



For me the prices are kinda steep on Kodecloud, and I am afraid that I cant review the course in the future for reference after I pass the exam.

The different price tiers is pretty confusing as well, since i cant really tell if i get the necessary courses from the basic subscription.



From what i read the practical labs/ playground are also available on Udemy as well.



Lastly, does anyone know do i need to go through the "Kubernetes for the Absolute Beginners - Hands-on" before the CKA course? I already know docker.



Could you please share your experience and hopefully point me in the right direction?

DevOps as a fresher

I am currently in 6th semester of my computer science degree. I am interested to learn DevOps but some of the folks I know are saying it's not a fresher thing. Companies don't hire fresher's. I just wanted to know is this true because I have seen some people saying you can get in to DevOps roles as a fresher. If yes please let me know how.

What are the skills I need to learn and feel free to share any resources if you know.

Looking for beta testers for CTFreak, an IT task scheduler

Hi there!

I am the author of CTFreak, an IT task scheduler with mobile friendly UI dedicated to the concurrent and remote execution of Bash / Powershell / SQL scripts through SSH, (among other things)

I'm finalizing ansible integration for the next release, and I'm looking for a few beta testers that are willing to give some feedback (primarily on ansible integration, of course 😉).

Ansible integration will consist in providing a new type of task dedicated to the execution of an ansible playbook, with the idea of delegating to CTFreak the management of the inventory and the concurrent execution of the playbook on different nodes (which allows to generate a log file per node).

There are a few restrictions to bear in mind regarding the scope of integration:

- Windows nodes are not taken into account

- CTFreak must be installed manually on a Linux server

In exchange for detailed information on your use cases and feedback during the beta phase (which should last 2 to 3 weeks), I'm offering a one-year license on STARTUP Edition.

If any of you are interested, let me know by DM!

I don't know if I'm just way to inexperienced or it is really that complicated.
I need like 5 business days to create AWS infrastructure, Pipelines and change my code (env variables and appsettings) to run on one stages. And there is zero IaC.

I am a Lead Dev for a client project. I have 3 developers in my team.
We are creating a small app with postgreSQL, AWS S3 Bucket, AWS DynamoDB, Backend, Frontend.

But is is so damn much manual labor!

Requesting Resume review

Hello,
Hope you all are doing great! I’m looking for feedback on my resume before I start applying for roles. I’m unsure which role would be the best fit—while my work falls under the SRE umbrella in my organization, I feel it’s not core SRE.

I primarily work with Grafana, Prometheus, and other ad hoc tasks. I feel I lack technical depth and want to improve. Having been in the same company for six years, I’m now looking to grow and explore new opportunities.

I’d love any suggestions on improving my resume formatting, as well as advice on navigating career growth and life in general. Also, I’d really appreciate insights on what types of roles I should target.

Apologies for any mistakes in this post, and thanks a lot for your time!
