容器运行时 Docker 部署

Docker安装

所有worker节点

mkdir k8s-worker/docker  -p  && cd k8s-worker

wget -O docker/docker-ce.repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

修改 Docker 配置文件

cat > daemon.json << "EOF"
{
  "exec-opts": ["native.cgroupdriver=systemd"]
}
EOF

cri-dockerd 安装

wget -O docker/cri-dockerd-0.3.4-3.el7.x86_64.rpm https://github.com/Mirantis/cri-dockerd/releases/download/v0.3.4/cri-dockerd-0.3.4-3.el7.x86_64.rpm
