<p>Is there a maximum number of namespaces supported by a Kubernetes cluster? My team is designing a system to run user workloads via K8s and we are considering using one namespace per user to offer logical segmentation in the cluster, but we don't want to hit a ceiling with the number of users who can use our service.</p>

<p>We are using Amazon's EKS managed Kubernetes service and Kubernetes v1.11.</p>

<p>This is quite difficult to answer which has dependency on a lot of factors, Here are some facts which were created on the <strong>k8s 1.7 cluster</strong> <a href="https://github.com/kubernetes/community/blob/master/sig-scalability/configs-and-limits/thresholds.md#kubernetes-thresholds" rel="noreferrer">kubernetes-theresholds</a> the Number of namespaces (ns) are 10000 with few assumtions </p>
