Are there any DevOps or Infrastructure-type jobs where you work on boats?

Weird Q. But any need for these roles on oil rigs or cruise ships or anything similar? I had a random thought that it might be a fun alternative / break out of normal society for a while. But no idea if there is any demand for these kind of jobs in those environments. Presumably basic IT support, but not sure what else.

Looking for devops role ; need suggestion

Hi there everyone.

I’m a student currently doing a bachelor in here USA and looking for devops role.

Primarily I did devops for 1 year maintaining full stack apps, automated build using GitHub ci cd and reproducible servers with nixos. I’m proficient with rust, python and basic web development but I’m sure I can learn anything quick if there’s any new tech part to learn.

My current financial situation is going really tough right now. if there’s anyone who’s got job or have any opportunities. Please help me out.


Appreciate it 🙏

Interview Mess - DevOps

I'm giving interviews these days and I've good understanding of DevOps tools and technologies. But whenever I go into the interviews, interviewers start asking troubleshooting questions and other issue and I've not faced this issue so I'm not sure how to answer these questions. And gets rejected. I know I'm not expert in all these but none of them consider basic understanding of the same.. getting rejected day by day... 😕
What should I do..? There is so much to learn.

Monitoring setup with Grafana Alloy and Mimir

Hello everyone, currently I'm working in startup and we just have one cluster that we would like to have logging and monitoring setup. This is first time Im setting up logging and monitoring and I am not able understand if I will need Prometheus or not as Alloy can directly write to the Mimir. Is there any benefit we get if Alloy sends data to Prometheus and Prometheus writes to Mimir?

Seeking Some Words of Wisdom

Hi all,

I’m currently working as a Platform Engineer at a large multinational company, but my journey here has been anything but straightforward. I started my career 11 years ago as a .NET developer. After a few years, I began feeling stagnant and found myself drawn to the world of cloud technologies. Driven by this passion, I started teaching myself everything I could from online tutorials and guides, determined to gain the necessary skills in platform engineering.

About 3-4 years ago, I took the leap and fully transitioned into the Platform Engineering space, and, I’m happy with that decision.
However, I’m constantly reminded of just how fast the world of DevOps evolves—especially with the rise of GenAI, MLOps, and other emerging technologies. It’s exciting, but also overwhelming at times.

No matter how much I learn or how many projects I work on, I can’t shake the feeling that it’s never enough. I struggle with the question of whether I’m truly “qualified” to call myself a Platform Engineer. I don’t hold any formal Kubernetes or cloud certifications, but I’ve gained hands-on experience working with these technologies. Still, the lingering doubt remains—how much is enough?

I find myself feeling uncertain about areas like networking and Linux, especially since I transitioned from a purely Windows-focused background. This sense of not knowing enough sometimes makes me question my place in this field.

I’m hoping to hear from others who may have faced similar feelings or have advice on how to navigate these challenges. How do you balance continuous learning with feeling confident in what you already know? How do you define “enough” in a field that never stops changing?

Automate Deployment config changes?

There is something I have always been wondering about how to best solve this. The problem:

Deployments in Kubernetes cluster based on helm and ArgoCD. Now most things can be automated quite easily with this setup but what always seems to become troublesome in bigger projects are changes to configmaps and secrets especially staging these when they are environment specific.

Current setup:

Developers try to document all required changes and set values in a secret store that is referenced. This however still requires a lot of effort before deployments to change some environment variables in helm charts and secret references etc.

Is there a setup to fully automate this easily? We have a ton of different staging environments >25...


Edit: All generic environment variables and configmaps get baked into the helm base charts/images already

Seeking Career Progression Advice

Hey everyone,

I'm looking for some guidance on my career progression and would really appreciate your insights.

I started off as a DevOps engineer focused on containers, cicd, automation scripts, etc. Over time, my career led me more towards AWS, and I ended up obtaining several AWS certifications (8). This compounded my interest and skills in AWS, and I guess you could say I'm a cloud engineer now. I still support applications through cicd and containerizing, etc, but that's not the highlight of my skills.

Lately, I've been feeling like I've been stuck in the same role or rut for too long. I considered moving towards DevSecOps or application security, but that seems to be along the same track I started off in (containers and pipelines).

I'm curious about what career progression paths I can explore now. Given my background, what roles or areas might be a good fit? Has anyone else been in a similar situation and made a transition that revitalized their career?

Thanks in advance for sharing your thoughts

How to authenticate paid software?

Context:
I have a freemiun app, most features relies on a local LAN server, except for a proxy server and in app features for the admin of said server.

What I've been thinking..

Method 1
- Being online most of the time to ensure the user is using a valid key, but this creates a conflict with the core of the app (minimal use of the network)

Method 2
- Ship the app with a public key to validate the user key, this key has encrypted data of the user and expiration date, this is stored on the client's device. Upon key expiration it's invalidated and removed from the device. The user has to pay again. (This one only relies on the network once per key activation)

What other methods can you think of for this context?

Terraform Test or Terratest

We currently don't have any sort of unit tests for our modules and I was checking into both of these tools. They both have their pros and cons, but I wasn't sure what people thought about the pros and cons of each at this point. I picked up enough Go to play around with Terratest and I do like how easy it is to import a module and do basic things that I'd want to do. Of course the native Terraform testing framework uses HCL so that's a big plus, but I don't feel like there are many examples out there comparatively and that it would be harder to achieve certain tests not having the flexibility of a programming language like Go. Curious to hear what you think.

Suggestions on what to improve on in order to take bigger rolesband advance career.

I have been at my current place for 6 years and it's been a team of 3 managing a multimillion infrastructure spend. I came on to migrate us from on prem to azure and I had full control of what we use. I recruited another engineer I knew at my last job and we have run a really stable environment over the last few years with the third guy that was hired from within the company.

We use terraform, cinc, PowerShell, and jenkins to manage all infrastructure and automation. I am extremely strong in azure and PowerShell. I would say fairly strong in the other two, and I have a little experience with some other things..

We are a msft shop and everything is running on VMs but we've got some things in Linux and we're integrated in some azure services like azure files, redis, blob, and networking services like virtual wan.

We were moved to GCP after we got bought and its ok, but I'm getting bored. I like to do infrastructure architecture and environment build outs but its just maintaining a lot of it now.

Are there industry trends/new technologies that I should be learning about to further my career for other possible jobs? I was thinking learn some more on containerization but I'm not sure. I've done cloud infrastructure and automation for about 10 years now.

Any input is appreciated.

Memory waste and cold start

Drowning in config files and CloudWatch logs. Two issues I was thinking about sharing with you and gathering your thoughts:
1. Memory Waste: A study found 95% of serverless functions use <10% of allocated memory. How are you optimizing this in your CI/CD pipelines?
2. Cold Starts: Balancing performance vs. cost is tricky. What's your strategy for managing this, especially for low-traffic functions?

I'm curious:
* What tools or custom scripts are you using for serverless optimization?
* How are you handling observability and cost management for serverless in your DevOps workflows?
* For those at scale: Any tips on maintaining CI/CD speed and configuration management as your serverless footprint grows?

shared developer setup for macOS and windows

Hello,

recently we have finally been able to use MacBooks in our company, i.e. also for our customer projects.

Previously, development was done purely on Windows laptops and there was a setup with SEU-as-Code that created an isolated environment with IntelliJ, Git for Windows, VirtualBox for a Devbox and SQLPlus.

The environment was then assembled as required using configs, start and env scripts.

However, the whole setup is very old and should have been modernized a long time ago anyway, as SEU-as-code has not been developed further for years. Now they want a new setup and support for both operating systems

The current statement from our leads is that the costs for the modernization will increase by 50% if we want to support Mac and that they would like to use separate setups.

However, I find it hard to imagine that we are the first to run into this issue and that there is no practical solution, especially if the setup is developed from scratch and no technical debt has to be taken into account. Also, both leads were not fans of the Mac launch before, so I'm not sure if this is a purely objective opinion.

The question here in the round whether someone already has experience with this and perhaps has something like this in use in their own company.

Ideas, tools, anything would help, as I'm currently worried that our bosses might scupper the whole issue of Macs because of the statement.

Or does anyone know a better subreddit for the question if I'm wrong here, I haven't found one so I'm asking here in the hope it's OK.

Buildfarm on Kubernetes

Anyone running production-grade Bazel Buildfarm (I guess it's just Buildfarm now) setup using the official helm chart with Linux, Windows and macOS workers? Just curious about experience with it, especially autoscaling, CAS management, overall configuration etc.

I have a setup with all that, but without autoscaling (because when Linux workers scale down buildfarm still looks for what was in their CAS for some reason and builds fail when they don't find something that was cached - instead of just rebuilding it, for some reason). Windows workers performance is kinda dogshit, but that may be about our custom toolchains - or just Windows being Windows keeping that CPU usage under 40% pretty much always.

As we're on AWS / EKS, we're also thinking about moving CAS to S3. Anyone here had something like that?

Software Engineer Jobs Report 10/16: Every week I spend hours scraping the internet for recently posted software engineer jobs. I hand pick the best ones, put them in a list, and share them to help your job search. Here is this weeks spreadsheet. 260+ roles USA and aboard. Devops roles included.

Hey friends, every week I search the internet for software engineer jobs that have been recently posted on a company's career page. I collect the jobs, put them in a spreadsheet, and share them with anyone whose looking for their next role. All for free.

I hand pick the ones I know are good roles, with market salaries, and no glaring flags (ex: I generally only put roles with posted salary bands). Though its not easy to tell if the roles require leetcode or not. I want to figure out how to get the information in the future.

The data is sourced by my own web scraping bots, paid sources, free sources, VC sites, and the typical job board sites. I spend an ungodly amount on the web so you don't have too!

About me, I am a senior software engineer with a decade of work history, and ample job searching experience to know that its a long game and its a numbers game.

If there are other roles you'd like to see, let me know in the comments.
