I've gone through several interviews, and most of the roles have required production Kubernetes experience. None of my previous employers used Kubernetes, although I understand the core concepts and have deployed workloads on AKS as a personal learning project. What's the best way to close this experience gap? Should I describe my personal work differently, pursue a certification, target broader DevOps roles, or simply keep applying without claiming commercial production experience?

Try running a small service as a serious side project rather than just following a tutorial. For example, deploy an application or game server for real users, automate releases, monitor it, respond to failures, and record the decisions you made. It doesn’t need enterprise scale to be valuable. You can truthfully describe it as operating a Kubernetes-hosted service in your own environment while making it clear that it wasn’t company production infrastructure.
You may also be targeting roles that are too specialized for your current background. Consider broader DevOps, platform, or cloud infrastructure positions where Kubernetes is one part of the job instead of the entire focus. Highlight related experience with Linux, containers, networking, CI/CD, and observability tools. Many teams can teach their workflows, but you’ll have a better chance if you’re honest about what you know and can explain exactly what you’ve built.
Don’t claim production experience if you haven’t had it professionally. A technical interviewer can usually uncover that quickly by asking about incidents such as debugging CrashLoopBackOff errors, handling node drains, rolling back failed deployments, managing alerts, or controlling cloud costs. Instead, turn your AKS project into something substantial and easy to review: use GitOps with Argo CD, add monitoring, logging, tracing, resource requests and limits, deployment rollbacks, and document the tradeoffs and failures you encountered. A public repository and a short write-up can demonstrate much more than an unverified resume claim.
Certifications can help get your application noticed, especially the KCNA or KCSA as entry-level options, followed by the CKA or CKS if you want a deeper credential. They won’t replace hands-on experience, but they can validate that you understand Kubernetes and give you a structured way to fill knowledge gaps. Be clear that your cluster work was personal or self-directed rather than commercial production experience.
Be straightforward in interviews: say that you haven’t managed Kubernetes commercially yet, then walk through your AKS project and a specific problem you solved. Employers asking for production experience are often trying to find people who have dealt with systems breaking, not merely people who recognize Kubernetes terminology. Honest, detailed examples usually make a stronger impression than an inflated resume line.
The important distinction is being able to explain what you actually operated and what limitations it had. A small cluster won’t teach you everything about high availability or large-scale traffic, but it can still show that you’ve dealt with real deployments, failures, upgrades, and maintenance.
