Debian12 安裝kubernetes1.28

YueQAQ發表於2024-06-22

Prerequisites

  • Minimal Installed Debian 12 /11
  • 2 CPU / vCPU
  • 2 GB RAM
  • 20 GB free disk space
  • Sudo User with Admin rights
  • Stable Internet Connectivity
  • Ensure that each node can communicate with the others via a reliable network connection.

1. 設定hostname和hosts檔案

 sudo hostnamectl set-hostname "master"      // Run on master node
 sudo hostnamectl set-hostname "node1"    // Run on 1st worker node
 sudo hostnamectl set-hostname "ndoe2"    // Run on 2nd worker node

/etc/hosts 配置

10.0.8.2 master
10.0.0.6 node1
10.0.8.15 node2

2. 關閉所有節點的swap

目的：1. 平滑執行 2. 讓記憶體洩漏的容器快速死亡

sudo swapoff -a
sudo sed -i  '/ swap / s/^\(.*\)$/#\1/g' /etc/fstab

debian 非root下可能沒有設定/usr/sbin 的環境變數，導致無法執行一些命令，設定下即可。

3. 新增防火牆規則

4. 安裝Container

安裝前所有節點設定核心引數

$ cat <<EOF | sudo tee /etc/modules-load.d/containerd.conf 
overlay 
br_netfilter
EOF
$ sudo modprobe overlay 
$ sudo modprobe br_netfilter
$ cat <<EOF | sudo tee /etc/sysctl.d/99-kubernetes-k8s.conf
net.bridge.bridge-nf-call-iptables = 1
net.ipv4.ip_forward = 1 
net.bridge.bridge-nf-call-ip6tables = 1 
EOF

執行 sudo sysctl --system 使得引數修改生效

安裝Container

sudo apt update
sudo apt -y install containerd

在所有節點生成匯入預設配置

containerd config default | sudo tee /etc/containerd/config.toml >/dev/null 2>&1

使用SystemdCgroup配置，將 ‘SystemdCgroup = false’ 修改為 ‘SystemdCgroup = true‘

sudo vi /etc/containerd/config.toml

重啟服務使配置生效

sudo systemctl restart containerd
sudo systemctl enable containerd
  1. 新增kubernetes源
echo "deb [signed-by=/etc/apt/keyrings/kubernetes-apt-keyring.gpg] https://pkgs.k8s.io/core:/stable:/v1.28/deb/ /" | sudo tee /etc/apt/sources.list.d/kubernetes.list
` curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.28/deb/Release.key | sudo gpg --dearmor -o /etc/apt/keyrings/kubernetes-apt-keyring.gpg`
