Do you have practical experience in configuring and managing Kubernetes as a system administrator?

Yes, I have experience configuring and managing Kubernetes as a system administrator. My responsibilities included:

• Deploying and configuring Kubernetes clusters (based on kubeadm, Rancher, or cloud providers).
• Managing cluster resources: setting up namespaces, quotas, limits.
• Configuring network policies and services (Ingress, LoadBalancer).
• Monitoring cluster health using Prometheus, Grafana.
• Updating cluster components and managing versions.
• Setting up RBAC for access control.
• Automating application deployment with Helm charts.

For example, to set up a cluster using kubeadm, the following commands were executed:

kubeadm init --pod-network-cidr=10.244.0.0/16
kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

Then, roles and access rights were configured, along with monitoring and logging.
