What's the next certification to goal?

I obtain the KCNA certification two weeks ago and i think CKA is the next certification to goal. It's natural course the CKA certification and i have pratical experience for one year and half with kubernets. Althought no provide the cluster, just delivery the applications by argocd and gilab. It's the better choice CKA exam? Or it's better investing in some cloud certification? I mean, not about the knowledge but the profile improvement, it's better choice Kuberstraount follow or some cloud provider like AWS to goal?
I have solid background like as sysadmin and obserbability, but still not considered myself a specialist.

What’s your go-to tool for monitoring Kubernetes clusters?

I’m managing a small Kubernetes cluster and struggling to get good visibility into resource usage and pod health. I’ve been using Prometheus with Grafana, but the setup feels clunky for my needs. What tools do you use for monitoring your K8s clusters, and what makes them stand out?

Winscp using ADSSHlogin extension

is there anyone who tried to use Winscp to connect to a linux VM using the ADSSHlogin extension?

I can use correctly the ssh command with the following commands:

set /p ipAddress="Enter IP of VM you're connecting to: "

call az login --use-device-code

call az ssh config --ip %ipAddress% --file %userprofile%\\.ssh\\sshconfig

call az ssh vm --ip %ipAddress%


but then I try to use the private key generated to use winscp wihtout any success

My journey in building a GNU/Linux aarch64 (ARM) system

In these times of rapid technological change, I feel the need to go back to the roots... That’s why I started this project — partly as a personal exercise to refresh my fundamentals, but also to create a solid foundation for the upcoming DevOps & SRE Academies I’ll be organizing in the next few months at my work place. Here are some notes from my journey of building a GNU/Linux aarch64 (ARM) system: https://devopstribe.it/2025/08/18/my-journey-in-building-a-gnu-linux-aarch64-arm-system/

how much do you trust AI with deployment?

what the title says.

i feel that deploying nowadays feels either too magical (but locked into a certain rigid framework) or too manually to the point where you're better off just going straight to a cloud provider.

As these tools start developing their own alternatives, I'm curious on how other engineers feel about AI doing deployment for them. Would you ever trust an AI tool to actually deploy an app or infrastructure end to end? If not, why? When would AI be good enough to trust it like that?


cheers!

Pivoting back to cloud-native development and DevOps

Hey everyone,

I’m looking for some insight and maybe a bit of guidance. I have \~5 years of experience in software development, most of it in cloud-native development (mostly with Azure). I have a couple of AWS certs (Solutions Architect and Developer Associate) and used to work in a role where I was pretty deep into the cloud stack—containerized workloads, IaC, CI/CD pipelines, microservices, etc.

Earlier this year, I made a career move into embedded systems for better pay and what I thought would be an interesting change of pace but I’ve found I really don’t enjoy the work. It’s very far removed from what I liked about building and deploying in the cloud—things feel much slower, less flexible, and I miss working with modern DevOps tools and practices.

Long-term, I’m aiming to become a solutions architect, ideally on the cloud side. I’m trying to figure out the best way to pivot back into that world.

A few questions for anyone who’s been in or adjacent to this path:

1. What’s the current and near-future outlook for cloud-native development and DevOps roles?
2. Is there still strong demand for people with cloud experience and certs?
3. Any advice on how to make myself more marketable again for cloud or DevOps roles?
4. Would aiming directly for a junior/pre-solution architect position be realistic, or should I try to get back in as a cloud engineer/developer first?

Appreciate any thoughts or experiences you can share.

I got offered a dev ops role over help desk. Should I take it even though I can fail?

I’m more of a jr sysadmin. Went to school for computer science. Have programmed little since graduating few years back. The majority of my work revolves around help desk, and I’m looking to break away from that once and for all.

For two months I asked the security department if I can work with them on some tasks because I want more things to put on my resume and learn.

Well they know I want to get out of help desk related tasks so they offered me a role where my main responsibility would be using puppet to do configuration management on the servers. I was apart of the puppet training. I would also be doing other security related tasks.

I don’t do much programming, but should I accept this role? Can I learn most of it on the job? To tell you the truth I don’t want to be on the operations side of things much anymore. I really regret not doing programming outside of school.

Basically should I take this opportunity? I don’t think my pay is adjusting but I much rather do this role, it’s just I’m starting from not much experience. But I feel like I’ll be a lot more motivated to learn and better myself outside of work because I have a clear path.

How to make a dead project alive?

I'm a DevOps engineer working for a US based telecommunication company. We've been using CISCO as our vpn provider for years now. Apparently, it looks like CISCO is having licensing problems and we cannot go ahead with it for the long run. Before I joined, the previous engineering manager suggested that we should use Nordlayer as a replacement for everything we do with CISCO. He made a plan, convinced everyone that it'll work and suddenly he left the company. Now in the DevOps team it's only me and newly joined manager. Other people at company mentioned that previous manager had all the poc setup in our AWS, but as I checked it's not.

Basically what we want to do is make a connection between our DC to AWS via Nordlayer!

There's no documentation on how this thing worked previously, but management tells us that it needs to be up. We contacted Nordlayer support and they also do not have any documentation since it was a poc setup. So we're kinda stuck and the heat's on me because I'm responsible for AWS and previous setup was present in AWS. So I'm really not sure what needs to be done!
Thought of posting this here because I'm sure everyone must've gone through this situation once in there career to finish what's been dead for years. Help me out.

Docker Setup for App with Frontend + 2 Backends + Certbot

Hi there,

I want to have a "simple-to-maintain" setup for having the following setup:

* Certbot
* Nginx (as reverse proxy sending traffic to backend & frontend)
* Two backends
* Frontend (Angular app)

For now I would do the following:

Certbot on the host without docker. To me it seems that having it inside docker-compose is too much of a hassle. The setup will be standalone so there will not be any other services requiring is to be in an isolated environment.

Nginx: To me it seems that it does not offer much benefits to put it into docker?

Backends: dockerized apps Inside a docker-compose

Frontend: How would you serve it? Would you rather put it on the host (since nginx is on the host already) or dockerize it (if so how?)?

What's your take on the setup?

Best Course+Certification for Devops

I am a currently pursuing BTech CSE and learning cybersecurity.

1. Want to know if DevSecOps is a viable field to get into in the future.
2. I will definitely need to learn Devops whether i choose to get into devsecops or not. Can someone please suggest some certification that i can aim for, preferably with a course accompanying it.
3. Which Platform do you think i should learn as a cloud platform(AWS/Azure) and Container Tools(Docker/Kubernetes), as i believe they both go hand in hand(correct me if i am wrong).

Is my plan valid

So I am actively learning DevOps related skills such as tools methodologies, hands on practice labs all by myself. I don't really have any job experience. Though I am currently doing a devops internship.
Which has almost 1.5 months remaining to complete. After that internship I work remotely as a freelance data scientist where my friend gets all the projects for putting food in the table so I am working almost 16 hrs daily.

This routeen is very taxing on my health so.

My Plan
After finishing my internship I plan to keep doing the freelance work, and then keep learning DevOps related stuff by myself as I have a clear direction now. To cater the experience issue I plan to get certs.
The cloud practitioner
Solutions architect
And maybe the sys admin professional.
And I know I will not just preparing for the cert but actual practice first and cert exams at the end.

So what do you guys say.

Getting a relevant job at the place I am an intern at might be a possibility but it does not seem likely. Even if I do get a job there, they use old styles stuff on prem servers, windows servers vms. Somehow it is related too.

In short: this is a bad company pays less , minimal learning.

Thanks

Saving audit logs

Hi,
How can I best save audit logs for a company?
I tried using Grafana with BigQuery and GCS archive. The storage cost in GCS is cheap, but the retrieval fees from GCS are very high, and also BigQuery query costs add up.

Any advice on better approaches?

Anyone else hit a wall with CI/CD pipeline bottlenecks?

Last week, our team’s CI/CD pipeline started choking during a big release. We’re using Jenkins with a bunch of custom scripts, and it took hours to debug why our tests were hanging. Turned out, a misconfigured Docker image was clogging the build queue. We fixed it by pruning old images, but it’s clear our setup needs an overhaul. Have you dealt with pipeline bottlenecks like this? What changes or tools helped you streamline your CI/CD process?

Manage multiple Lambdas using container images

Hi r/devops. We have a few Lambda functions deployed using container images. All of them use the same Dockerfile but we have different CI processes for building and pushing images to ECR, and updating the Lambda separately using the commit tag. It seems quite painful to manage 10s of repos and building/updating images. Was wondering how this should be ideally handled. Do you guys use a single ECR repo and use an image from this repo to update/deploy all Lambda functions? Any additional info is appreciated.

Concerns about Renovate

I have been trying to get Renovate to run locally on my computer locally without providing a PAT(in dry-run mode) or onboarding my repository and its proving challenging. I know I'll have to provide a PAT to create a PR but its simply not working locally. Using the Renovate Github APP is easy as pie but I have concerns over security and them just using my private codebase to train the LLM or whatever.

Documentation, tutorials, and general conversation on how to run Renovate locally is very sparse and generally doesn't work. I've even given chatGPT a shot for a general explanation and error after error after error.


Has anyone here had luck working with Renovate in a CICD pipeline? Or locally?

Basic "enterprise ready" AWS setup review

Need some advice! I want to standardize the terraform setup for my startup. Requirement is to keep things in Terraform and avoid using paid platforms.

Here's what I've used in the past that worked well:

## AWS Setup

WAF for firewall (DDoS protection, rate limiting, known IP blocking etc)

ALB for load balancing

Cert Manager for domain resolving

EKS cluster + ec2s for services (autoscaling)

RDS Postgres

AWS Secrets Manager for env vars

Logs on Cloudwatch -> pipe stdout to Grafana or DataDog


## CI/CD
Github Action workflow for new code releases, upon merging to main:
1. Test, compile, create new Docker image with version tag
2. Push image to AWS ECR
3. Update helm charts values (release version)
4. Deploy with helm (redeploys the pods)


I liked this setup so far because it scales easily, relatively headache free (once you get it working) and is an easy sell when selling to large enterprises ("robust", data doesn't leave our systems, etc).

Considering Fargate instead (simpler/cheaper?), but I only have experience with EKS. Thoughts?

Gaming API latency: 100ms London, 200ms Malta, 700-1000ms NZ - tried everything, still slow

Running a g@ming app backend (ECS/ALB) in AWS eu-west-2. API latency is killing us for distant users:

\- London: 100ms

\- Malta: 200ms

\- New Zealand: 700-1000ms



Tried:

1. CloudFront - broke our authentication (modified requests somehow)

2. Global Accelerator - no SSL termination

3. Cloudflare + Argo - still 700ms+

4. Cloudflare → Global Accelerator → ALB - no improvement

Can't go multi-region due to compliance/data requirements.



Is 700ms+ just the physics of NZ→London distance? Or are we missing something obvious? How do other platforms handle this?

We seem to have an antagonistic relationship with our infra/devops team, and I'm not sure what to do

I've worked at many places but this is the first time I've encountered this. Basically we are a small company that is handling a very complex, very large cloud infrastructure. There's about 5 people on the devops team and I get the feeling that they are overworked and under constant stress. I feel this way because our interaction with their team are often either short and curt (ie we would ask a question and they would answer with yes or no and act annoyed if we ask for more details), or get heated with blame/responsibility shifting. They seem very eager/glad to get anything off their plate, basically the attitude is "your app broke this, pls fix asap, it's not our problem". There is like one guy on the team who is nice and patient and helpful but he seems to be the exception..everyone else is like "I'm too busy, file a ticket first and we'll get back to you."

I've actually made a similar post about this before about how hard it is to work with the devops team, but I think I understand what they are going through, I just don't know how to make things better. Their team manager is also not an easy guy to communicate with, he seems even busier and barely responds to any messages.
