# CRI-O安裝
1. 設置 CRI-O 存儲庫：

# 設定 OS 和 VERSION 變數
OS="xUbuntu_20.04"
VERSION="1.23"

# 將 libcontainers 穩定版儲存庫添加到 APT 來源
echo "deb [signed-by=/usr/share/keyrings/libcontainers-archive-keyring.gpg] https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/$OS/ /" | sudo tee /etc/apt/sources.list.d/devel:kubic:libcontainers:stable.list

# 將 CRI-O 穩定版儲存庫添加到 APT 來源
echo "deb [signed-by=/usr/share/keyrings/libcontainers-crio-archive-keyring.gpg] https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable:/cri-o:/$VERSION/$OS/ /" | sudo tee /etc/apt/sources.list.d/devel:kubic:libcontainers:stable:cri-o:$VERSION.list

# 創建用於存儲 GPG 金鑰環的目錄
sudo mkdir -p /usr/share/keyrings

# 下載並添加 CRI-O 儲存庫的 GPG 金鑰
curl -L https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable:/cri-o:/$VERSION/$OS/Release.key | sudo gpg --dearmor -o /usr/share/keyrings/libcontainers-crio-archive-keyring.gpg

# 下載並添加 libcontainers 儲存庫的 GPG 金鑰
curl -L https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/Release.key | sudo gpg --dearmor -o /usr/share/keyrings/libcontainers-archive-keyring.gpg

2. 安裝 CRI-O

# 更新 APT 包索引
sudo apt-get update

# 安裝 cri-o 和 cri-o-runc 套件("-y" 選項表示自動回答 "yes" 到所有提示，使安裝過程自動進行)
sudo apt-get install -y cri-o cri-o-runc

3. 啟用 CRI-O：

# 重新加載 systemd 管理器配置
sudo systemctl daemon-reload

# 啟用並立即啟動 CRI-O 服務(enable:設定 CRI-O 服務為開機自動啟動,--now:現在就立即啟動)
sudo systemctl enable crio --now

4. 配置 CRI-O

# 創建 CRI-O 配置目錄(-p:如果連父資料夾都沒有的話也一併創建)
sudo mkdir -p /etc/crio/crio.conf.d

# 使用 nano 編輯器創建並編輯 NVIDIA 相關的 CRI-O 配置文件
sudo nano /etc/crio/crio.conf.d/99-nvidia.conf

寫入：

[crio]
  [crio.runtime]
     # 預設運行的容器為nvidia
    default_runtime = "nvidia"

    [crio.runtime.runtimes]
      [crio.runtime.runtimes.nvidia]
        # 指定 NVIDIA 容器運行時的路徑
        runtime_path = "/usr/bin/nvidia-container-runtime"
        # 指定運行時類型為 OCI (Open Container Initiative)
        runtime_type = "oci"

重啟

sudo systemctl restart crio
