k8s: v1.26.4;calico: 3.25.1
以虛擬機器器VMWare為例。
使用EFI 非預設BIOS啟動。如果不使用EFI,那麼後續安裝引導時也使用非EFI。
Controller-Panel節點(master)

CPU設定:2Core
記憶體設定:2GB
磁碟:20GB
網路卡設定:網路卡1(ens33)為自定義NAT
Worker節點

使用GUID分割區表,分2個區:
1)EFI System(EF00),Last sector: +500M (500MB)
2)Linux filesystem(8300) ,Last sector:<回車>(為剩餘容量)
gdisk /dev/sda
mkfs.vfat -F32 /dev/sda1 # ESP分割區 掛載 /boot
mkfs.ext4 /dev/sda2 # LFS分割區 掛載 /
mount /dev/sda2 /mnt # 掛載root分割區
mkdir /mnt/boot # 建立 /boot 目錄
mount /dev/sda2 /mnt/boot # 掛載boot分割區
lsblk # 檢視分割區掛載情況
vim /etc/pacman.d/mirrorlist # 在頂部新增如下映象伺服器

# 安裝系統
pacstrap /mnt base base-devel
genfstab -U /mnt > /mnt/etc/fstab # 生成分割區掛載表
編輯 fstab
vim /mnt/etc/fstab
# SSD的追加options 「discard,noatime」
編輯 /mnt/etc/pacman.conf檔案,加入下面的內容:
