Have you set up and configured a Kubernetes cluster in your practice?

Yes, in practice I have installed and configured a Kubernetes cluster. The process usually includes the following steps:

1. Infrastructure preparation — allocating virtual or physical servers.
2. Installing cluster components: kube-apiserver, kube-controller-manager, kube-scheduler on master nodes and kubelet, kube-proxy on worker nodes.
3. Configuring the cluster network using CNI plugins (e.g., Calico, Flannel).
4. Setting up storage and load balancers.
5. Deploying applications via YAML manifests, Helm charts, or operators.

It is important to ensure cluster security, configure RBAC, TLS certificates, and monitoring. Automation tools like kubeadm, kops, or managed services (GKE, EKS) are often used.
