1) Installing Containerd Packages

sudo dpkg -i containerd_deb/*.deb

#containerd module settings
sudo mkdir -p /etc/containerd
sudo containerd config default | sudo tee /etc/containerd/config.toml
sudo sed -i 's/SystemdCgroup = false/SystemdCgroup = true/g' /etc/containerd/config.toml

#starting containerd module
sudo systemctl restart containerd
sudo systemctl enable containerd
sudo systemctl status containerd

2) Installing Kubernetes Packages

sudo tee /etc/modules-load.d/k8s.conf <<EOF
overlay

sudo sysctl --system

sudo dpkg -i kube_deb/*.deb

systemctl enable --now kubelet.service
#Kubernetes installation check and startup
kubectl version --client && kubeadm version

3) Loading Kubernetes Images

sudo ctr --namespace k8s.io images import kube_images/kube-apiserver:v1.31.7.tar
sudo ctr --namespace k8s.io images import kube_images/kube-controller-manager:v1.31.7.tar
sudo ctr --namespace k8s.io images import kube_images/kube-scheduler:v1.31.7.tar
sudo ctr --namespace k8s.io images import kube_images/kube-proxy:v1.31.7.tar
sudo ctr --namespace k8s.io images import kube_images/pause:3.10.tar

sudo ctr --namespace k8s.io images import kube_images/coredns:v1.8.6.tar
sudo ctr --namespace k8s.io images import kube_images/flannel-cni-plugin-v1.6.2.tar
sudo ctr --namespace k8s.io images import kube_images/flannel-v0.26.4.tar

4) Kubeadm Init

sudo kubeadm init --pod-network-cidr="10.244.0.0/16" --control-plane-endpoint="<MASTER_SERVER_IP_ADDRESS>" --upload-certs --kubernetes-version=v1.31.7

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

To include worker node in cluster:

You can run the following command on master node to get the command to include in cluster as output and run it on nodes you will add as worker.

kubeadm token create --print-join-command

5) Creating Flannel

kubectl apply -f flannel_yaml/kube-flannel.yml

6) Loading Apinizer Images

sudo tar xvf apinizerImages.tar
cd apinizerImages

sudo ctr --namespace k8s.io images import manager_<APINIZER_VERSION>.tar apinizercloud/manager:<APINIZER_VERSION>
sudo ctr --namespace k8s.io images import worker_<APINIZER_VERSION>.tar apinizercloud/worker:<APINIZER_VERSION>
sudo ctr --namespace k8s.io images import cache_<APINIZER_VERSION>.tar apinizercloud/cache:<APINIZER_VERSION>
sudo ctr --namespace k8s.io images import integration_<APINIZER_VERSION>.tar apinizercloud/integration:<APINIZER_VERSION>
sudo ctr --namespace k8s.io images import portal_<APINIZER_VERSION>.tar apinizercloud/portal:<APINIZER_VERSION>

7) Installing MongoDB

sudo dpkg -i mongo_deb/*.deb

MongoDB configurations after installation are the same as the sections in MongoDB Installation on Ubuntu Operating System document.

8) Elasticsearch Installation

sudo mkdir /opt/elasticsearch
# Move the file inside the offline installation folders.
sudo mv elasticsearch/elasticsearch-7.9.2-linux-x86_64.tar.gz /opt/elasticsearch/
cd /opt/elasticsearch
sudo tar -xzf elasticsearch-7.9.2-linux-x86_64.tar.gz

After moving the installation file from its directory to /opt/elasticsearch/ folder, apply the steps on Elasticsearch Installation on Ubuntu Operating System page.
