containerd安装教程

一、下载containerd安装包

wget https://github.com/containerd/containerd/releases/download/v1.4.3/cri-containerd-cni-1.4.3-linux-amd64.tar.gz

二、解压安装包

tar  -zxvf  cri-containerd-cni-1.4.3-linux-amd64.tar.gz

三、移除不需要的文件（以下都在解压包下操作）

rm -rf etc/cni/
rm -rf opt/

#启动
systemctl status containerd
systemctl enable containerd
systemctl restart containerd

四、生成默认的配置文件

containerd config  default > /etc/containerd/config.toml

修改配置文件：oom_score = -999
