What's the average salary for a Kubernetes engineer?

Do you need a Kubernetes certification to apply for a job?

What technologies and cloud providers are often used with Kubernetes?

We analyzed 276 Kubernetes jobs from 2021 and found that:

- Prometheus is synonymous with monitoring. No one comes close.
