containerd部署

1.下载

• Github https://github.com/containerd/containerd/releases/download/v1.6.6/cri-containerd-cni-1.6.6-linux-amd64.tar.gz

2.配置

• 1.在/usr/local/下创建containerd文件夹，将解压后的usr/local文件夹下的bin、sbin复制到/usr/local/containerd文件夹下，然后配置环境变量，配置完毕后执行source /etc/profile，执行runc --help和containerd --help测试，如有输出证明配置成功。

export CONTAINERD_HOME=/usr/local/containerd
export PATH=$CONTAINERD_HOME/bin:$CONTAINERD_HOME/sbin:$PATH

• 2.创建/etc/containerd文件夹，修改配置文件，执行containerd config default > /etc/containerd/config.toml，修改SystemdCgroup = true，添加镜像源https://5r6sntk6.mirror.aliyuncs.com。

• 3.将etc/systemd/system文件夹下的containerd.service复制到/usr/lib/systemd/system/文件夹下，修改ExecStart=/usr/local/containerd/bin/containerd，保存后退出。

• 4.启动服务

systemctl daemon-reload

systemctl enable containerd

systemctl start containerd
