I recently earned the CKA certification and have been studying Kubernetes seriously, but my current workplace uses Nomad and Consul instead. Our environment is relatively small and also includes non-containerized workflows, so Kubernetes has not been necessary.
I'm interested in platform or SRE roles that request two to three years of production Kubernetes experience. I'm confident I can build and operate realistic Kubernetes environments outside of work, and I've completed a couple of substantial capstone projects. What I lack are real production stories involving incidents, migrations, outages, scaling problems, and similar operational challenges.
How quickly can experienced Kubernetes engineers recognize when a candidate is exaggerating their production background? Would it be better to be transparent about my experience, and can a CKA, serious hands-on projects, and Nomad/Consul experience still make me competitive for roles that prefer production Kubernetes experience?

It’s not worth inventing production stories. Strong interviewers usually ask detailed follow-up questions about incidents, trade-offs, debugging steps, and operational decisions. Someone with real experience can keep going deeper, while exaggerated claims tend to fall apart quickly. Even if you get hired, you may immediately be assigned work that assumes the experience you claimed to have.
Create a realistic project that gives you concrete operational experience to discuss. For example, migrate a small Docker Compose application to Kubernetes and work through networking, secrets, persistent volumes, node affinity, upgrades, monitoring, backups, and failure recovery. It won’t be the same as running a large company’s platform, but it gives you genuine examples instead of made-up stories.
Be honest about what you’ve done and frame it well. Your CKA, Kubernetes projects, and experience operating Nomad and Consul show that you understand orchestration and platform concerns. Explain clearly that your Kubernetes work has been personal or project-based rather than production work, and emphasize the operational skills that transfer between systems.
A certificate is a useful starting point, but it doesn’t cover the full range of problems found in a business environment. Build something, operate it over time, deliberately break it, and document how you diagnose and recover from issues. That practical evidence will be more credible than claiming experience you don’t have.
