# 1. 在你的每个节点上，遵循安装 Docker Engine 指南为你的 Linux 发行版安装 Docker

sudo apt-get remove docker-doc docker-compose docker-compose-v2 podman-docker  ; 

sudo apt-get update
sudo apt-get install ca-certificates curl gnupg
sudo install -m 0755 -d /etc/apt/keyrings
# 国内装docker用清华的源
curl -fsSL https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

# Add the repository to Apt sources:
# 国内装docker用清华的源
echo \

  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

sudo mkdir -p /etc/docker

# 2. 按照源代码仓库中的说明安装 cri-dockerd
# 对于 cri-dockerd，默认情况下，CRI 套接字是 /run/cri-dockerd.sock
git clone https://github.com/Mirantis/cri-dockerd.git
cd cri-dockerd
make cri-dockerd


#1. 安装cri-dockerd
sudo dpkg -i cri-dockerd_0.3.7.3-0.ubuntu-jammy_amd64.deb
#2. 调整启动参数
sudo sed -i -e 's#ExecStart=.*#ExecStart=/usr/bin/cri-dockerd --container-runtime-endpoint --network-plugin=cni --pod-infra-container-image=registry.aliyuncs.com/google_containers/pause:3.7#g' /lib/systemd/system/cri-docker.service

#3. 设置开机自启动和查看cri-docker状态
sudo systemctl daemon-reload
sudo systemctl enable cri-docker

sudo systemctl status cri-docker
