Установку будем производить на Rocky Linux 8

систему будем разворачивать на 3 ноды

node1 192.168.30.32 master node2 192.168.20.33 node3 192.168.30.34

Добавим репозиторий(на всех нодах)

dnf config-manager –add-repo=https://download.docker.com/linux/centos/docker-ce.repo

dnf install containerd

dnf install docker-ce –nobest -y

systemctl start docker

Change docker to use systemd cgroup driver.

echo '{

"exec-opts": ["native.cgroupdriver=systemd"]

}' > /etc/docker/daemon.json

systemctl enable kubelet

systemctl start kubelet

На master node

kubeadm config images pull

kubeadm init –pod-network-cidr 192.168.0.0/16

если не работает закомментить в vim /etc/containerd/config.toml запрещенные плагины т перезапустить systemctl restart containerd

Рабочий репозиторий

проблема с tc

dnf install -y iproute-tc

проблема с kubectl get nodes

mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

You can bootstrap a cluster as follows:

1. Initializes cluster master node:

   kubeadm init –apiserver-advertise-address $(hostname -i) –pod-network-cidr 10.5.0.0/16

2. Initialize cluster networking:

   kubectl apply -f https://raw.githubusercontent.com/cloudnativelabs/kube-router/master/daemonset/kubeadm-kuberouter.yaml

3. (Optional) Create an nginx deployment:

   kubectl apply -f https://raw.githubusercontent.com/kubernetes/website/master/content/en/examples/application/nginx-app.yaml
