Best way to approach DevOps?

Pardon me if this question has already been asked.

I am looking to venture into the world of DevOps. I am quite a dedicated learner and I have a deep passion for the field and as such I should have no problem learning the same and putting it to practice. However, it is to my understanding that DevOps is not a Junior Role and as such I have decided to start learning System Administration then make my way up from there. My question is, is it feasible to focus entirely on System Administration courses for starters then learn the rest of DevOps content while carrying out sysadmin practices or I can just learn DevOps and still be knowledgeable enough to land a junior sysadmin role?

what's the point of devcontainers if it forces standardization?

I was under the impression that devcontaineres are a way to:

-> Specify a base image for everybody
-> If you use vscode, great, semaless layering. Else, add a few post-install scripts to drop waht you need into the project, great.

Then you have a base container with just only the needed build dependencies.

But like in practice, there's no such thing as "version controlled developer specific devcontainers", you have to centralize while not checking in core changes to the main repo.

My neovim setup might tick off, either somebody else's vim setup or someone who just wants vscode and nothing else (and I certainly don't want to pull in extra vscode stuff). Our project might not use python, but for my tooling I will get python anyways (neovim stuff). perfect use for devcontainers, I just install python post-install but committing that to the main repo? That... can easily get cluttered, if other people's devcontainer configs are there too.

Also, there are some user namespacing things (set uid gid etc) that might not belong in a build container but we'll worry about that later (also I think in practice you should have a separate deploy container, but we have not gotten to that level of automation yet, we have just started using build containers lol).

I guess, from more experienced developers, how do you deal with this issue where 5 different people have 5 different ide/dev workflows and you want minimal frictoin integrating with a devcontainer workflow?

Starting My Cloud Career — Which Certification Should I Pursue Next? Terraform, Kubernetes, or Azure Cloud Architect?

Hi everyone,

I'm at the beginning of my cloud career and looking for advice on which certification I should pursue next to boost my skills and job prospects. I have around 13 years of experience in telecom, networking, and IT fields, and a little hands-on cloud experience. I also have a solid foundation from my current certifications, which include:

* AWS Certified Solutions Architect – Associate
* Multiple Azure certifications (3x)
* Alibaba Cloud certifications (3x)
* Oracle Cloud Infrastructure Generative AI Professional
* CompTIA CySA+, Security+, PenTest+, Network Security Professional, Security Analytics
* CCNA
* ITIL Foundation

Given this background, I’m considering between:

1. Terraform Associate Certification (infrastructure as code)
2. Kubernetes Certification (container orchestration)
3. Azure Cloud Architect Certification
4. something else? please mention in comments

My goal is to solidify my cloud skills and eventually specialize in telecom cloud or cloud security.

For those experienced in the field, which certification would provide the best return on investment, credibility, and market demand? Also, is there a preferred order to take these certifications for someone starting out? Any insights or personal experience would be greatly appreciated!

Thanks in advance!

Kodecloud subscription vs Udemy course for Kubernetes, docker etc

I know there are a lot of courses available, even for free but I have not been able to self study or learn something since quite some time. I believe something like might help and I have heard they have good kubernetes resources. Kodecloud pro is very costly but it gives the benefit of playgrounds so I don't have to setup everything for which i often procrastinate.

So is kodeckoud pro worth it or should I stick to their udemy course?

Any good offline-first alternatives to Postman?

I’ve been hitting a wall with API clients lately. Most of them (Postman, Insomnia, etc.) really push cloud sync and accounts, but sometimes I just want a tool that works locally without sending data anywhere.

Things I’ve found so far:

Bruno → open source, collections saved as plain files. Works great with Git.

Hurl → totally scriptable, stores everything in text format.

Insomnium → fork of Insomnia before it went closed-source.

Apidog → supports offline debugging mode, which helps if you want something modern but not cloud-locked.


Do you think offline-first clients are underrated? Or is cloud sync just too convenient to give up?

Anyone solved ECS-to-Loki logging drop after EKS ASG scale-down

I’ve just deployed Loki to my EKS cluster and it’s working great overall.

I’m sending logs from a standalone ECS cluster to Loki via an NLB. The issue: in my DEV/QA environments, the EKS worker node ASGs scale down to 0 after hours and on weekends. The ECS tasks themselves keep running fine, but when the EKS nodes scale back up, those ECS tasks stop sending logs to Loki until I restart them.

Has anyone run into this before? Is there a way to fix it without restarting the ECS tasks?

AI/ML Learning path and Conferences

Hi all,

Im experienced devops engineer, as most of the people in this group. My current daily basics are cloud services, docker, kubernetes, CI/CD , automation and a bit etc.

Now DevOps folks are starting to join AI/ML projects and i see lot of work coming from DevOps teams: MCP, gpu sharding, schedule k8s data workloads, inference servers and more to come.

I wonder abouy the best learning path for DevOps to join the AI world ( i dont mean about creating AI tools for DevOps, i mean to get into the AI workd and collaborate with Data Teams).

Also conferences for us that will mean it,

On example is this i found in another reddit post: https://aws.plainenglish.io/ai-roadmap-for-devops-ce6e8f8a8d37

Question for CXOs & Leaders: How do you measure the business impact of DevOps?

I was talking with some tech leaders recently, and one theme kept coming up over and over again-DevOps is no longer just about automation and pipelines, it’s about driving business outcomes.

Some key challenges I keep hearing from CXOs:

* How do you show ROI of DevOps investments to the board?
* How do you balance speed, security, and cost while scaling?
* What metrics actually prove DevOps success in business terms?

👉 I’d love to hear from the community - how are you addressing these challenges in your organizations?

To make this conversation more interactive, we have also created a dedicated WhatsApp group where CXOs, managers, and practitioners exchange ideas, share case studies, and discuss leadership-focused DevOps problems.

If you're interested, DM me for the invite link (this group is for knowledge sharing only, not spam).

Looking forward to your feedback here too! 🚀

18x cost blow-up from retry storm + malformed JSON

We just ate $400 in 48 hours from a silent bug.
One request that should’ve cost $0.43 ballooned to $7.81 because a recursive JSON object turned into a 3.2MB payload and got shoved straight into the LLM as “context.”

Monitoring didn’t help — HTTP 200s everywhere, token usage looked high but plausible, cost alerts lagged by 6+ hours, and we had no payload size checks.

Fixes that actually worked:

100KB hard limit at API boundary
Per-request cost tracking with a $3 circuit breaker
Schema validation in CI to catch circular refs
Dedupe script (jq … | awk '$1 > 2')

Results: 91% fewer duplicate requests, and caught 2 more cost bombs (\~$300) before they hit the bill.

Anyone else validating payloads before they hit expensive APIs?

Can I install a cloud like environment in a laptop?

We develop enterprise applications, in azure cloud. But basically the services we use are db, web server, some functions and the service bus. The users and the workload are ridiculous, like in the range of hundred of users, nor even thousands.

The thing is that we deploy everything to cloud, for every environments. Some applications have 5/10 environments for dev only. Multiply by 10 or so integrated applications.

All based on terraform and kubernetes
Wouldn't be possible to setup few local PCs and deploy there? With docker or openshift?

Would it make sense moneywise, including the effort to maintain that? At least for development?

I Created an Open-source Container Security Scanning Dashboard

Good afternoon r/devops

I built [Harbor Guard](https://github.com/HarborGuard/HarborGuard), an open source tool for scanning Docker images. It brings several scanners into one web interface, so you don’t have to manage them all separately.

* Runs scans with these tools:
* Trivy
* Grype
* Syft
* Dockle
* OSV Scanner
* Dive
* Shows results in a single dashboard
* Stores scan history for comparison
* Provides REST API endpoints for automation

# Features

* Vulnerabilities grouped by severity
* Scan history and comparisons over time
* Layer by layer image analysis
* Export reports in JSON or ZIP
* Real time progress tracking



Looking for feedback on what features would make this most useful in real workflows.

* GitHub: [https://github.com/HarborGuard/HarborGuard](https://github.com/HarborGuard/HarborGuard)
* Demo: [https://demo.harborguard.co](https://demo.harborguard.co)

Why do people prefer managed/freemium platforms instead of just setting up open-source tools?

In my freelance career I always leaned toward open-source or free options because of budget limitations. I avoided freemium platforms from the start. During my early analysis I came to the conclusion that:

* Once you start with them (like Firebase, Firestore, Supabase, AWS Amplify, Netlify, Vercel, etc.), you get pulled into their ecosystem
* Switching providers/tools later becomes almost impossible.
* Billing grows exponentially once you scale, and by then it’s too late to pull out.

So I’ve always thought it’s safer to just set things up myself with open-source stacks. I have some notes I prepared years ago, after purchasing a server, it’s just simple steps I follow as a template: securing it, creating users, setting up firewall rules, installing the tools I need (load balancers, databases, Node, Java, etc.). I still use those same notes even now, with only rare updates.

My doubt is:

* Is the reason people still pick those managed/freemium platforms simply because they don’t know how to set things up themselves?
* Or is it more about convenience and speed?
* Or maybe businesses just accept the lock-in cost as part of the trade-off?
* Is there some hidden advantage I’m missing here from a DevOps perspective?

Would love to hear real experiences from people who’ve been down this path.

Anyone else have generally good experiences with AI tools?

When it comes to AI tools like Cursor, Copilot, Gemini, etc., it seems like it's nothing but an endless litany of opinions on how much they suck and how little they help.

Which is wild, because that's the exact opposite of my experience. I've been doing DevOps / SRE work for over a decade now and Cursor has massively sped up the amount of quality code I write. Especially when it uses your local repo for context.

The agentic self-prompting feature where it goes and asks the next logical question and works on it has been a huge time saver compared to writing a prompt, getting an answer, copy-pasting it, then repeating.

Sure, it has pitfalls, and it doesn't always get things right, but 90% of the time, it's very close to what I need and only needs some slight tweaks.

I use it primarily to write Python, Typescript and HCL, and it's done pretty well with each of those.

Anyone else out there finding AI tools more useful than not?

Learning DevOps

Hello, I am currently learning DevOps(self learning). I have deployed Gitea and Jenkins and right now, Jenkins pushes docker containers to my Gitea registry and they show up under packages. Is that good practice to leave it this way or do I need to have a separate server for containers?

I tried talking to ChatGPT and the outcome was with a well speced server it is acceptable. But I want to hear from people that actually do this on a daily. Your guidance will be highly appreciated.

How do you guys approach documentation?

Struggling with keeping docs updated and actually useful. Been trying different approaches and curious what's working for others.
