Install CNI plugins (required for most pod network):
```bash
CNI_VERSION="v0.8.2"
mkdir -p /opt/cni/bin
curl -L "https://github.com/containernetworking/plugins/releases/download/${CNI_VERSION}/cni-plugins-linux-amd64-${CNI_VERSION}.tgz" | tar -C /opt/cni/bin -xz
sudo mkdir -p /opt/cni/bin
curl -L "https://github.com/containernetworking/plugins/releases/download/${CNI_VERSION}/cni-plugins-linux-amd64-${CNI_VERSION}.tgz" | sudo tar -C /opt/cni/bin -xz
```
Define the directory to download command files
```bash
DOWNLOAD_DIR=/usr/local/bin
sudo mkdir -p $DOWNLOAD_DIR
```
Install crictl (required for kubeadm / Kubelet Container Runtime Interface (CRI))
```bash
CRICTL_VERSION="v1.17.0"
mkdir -p /opt/bin
curl -L "https://github.com/kubernetes-sigs/cri-tools/releases/download/${CRICTL_VERSION}/crictl-${CRICTL_VERSION}-linux-amd64.tar.gz" | tar -C /opt/bin -xz
curl -L "https://github.com/kubernetes-sigs/cri-tools/releases/download/${CRICTL_VERSION}/crictl-${CRICTL_VERSION}-linux-amd64.tar.gz" | sudo tar -C $DOWNLOAD_DIR -xz
```
Install `kubeadm`, `kubelet`, `kubectl` and add a `kubelet` systemd service:
```bash

mkdir -p /opt/bin
cd /opt/bin
curl -L --remote-name-all https://storage.googleapis.com/kubernetes-release/release/${RELEASE}/bin/linux/amd64/{kubeadm,kubelet,kubectl}
chmod +x {kubeadm,kubelet,kubectl}
cd $DOWNLOAD_DIR
sudo curl -L --remote-name-all https://storage.googleapis.com/kubernetes-release/release/${RELEASE}/bin/linux/amd64/{kubeadm,kubelet,kubectl}
sudo chmod +x {kubeadm,kubelet,kubectl}
RELEASE_VERSION="v0.2.7"
