+### Creating a local cluster
+```shell
+denis@denisserv:~$ kind create cluster --name kind-cluster
+Creating cluster "kind-cluster" ...
+ ✓ Ensuring node image (kindest/node:v1.32.0) ������
+ ✓ Preparing nodes ������
+ ✓ Writing configuration ������
+ ✓ Starting control-plane
+ ✓ Installing CNI ������
+ ✓ Installing StorageClass ������
+Set kubectl context to "kind-kind-cluster"
+You can now use your cluster with:
+
+kubectl cluster-info --context kind-kind-cluster
+
+Not sure what to do next? ������  Check out https://kind.sigs.k8s.io/docs/user/quick-start/
+```
+### Check if the cluster is running
+```shell

+CoreDNS is running at https://127.0.0.1:44065/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
+
+To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

+* Используется драйвер docker на основе конфига пользователя
+
+X The requested memory allocation of 1967MiB does not leave room for system overhead (total system memory: 1967MiB). You may face stability issues.
+* Предложение: Start minikube with less memory allocated: 'minikube start --memory=1967mb'
+
+* Using Docker driver with root privileges
+* Starting "minikube" primary control-plane node in "minikube" cluster
+* Pulling base image v0.0.46 ...
+* Скачивается Kubernetes v1.32.0 ...
+    > preloaded-images-k8s-v18-v1...:  333.57 MiB / 333.57 MiB  100.00% 1.97 Mi

+* Creating docker container (CPUs=2, Memory=1967MB) ...
+* Подготавливается Kubernetes v1.32.0 на Docker 27.4.1 ...
+  - Generating certificates and keys ...
+  - Booting up control plane ...
+  - Configuring RBAC rules ...
+* Configuring bridge CNI (Container Networking Interface) ...
+* Компоненты Kubernetes проверяются ...
+  - Используется образ gcr.io/k8s-minikube/storage-provisioner:v5
+* Включенные дополнения: storage-provisioner, default-storageclass
+* Готово! kubectl настроен для использования кластера "minikube" и "default" пространства имён по умолчанию
