1、配置containerd
#安装containerd yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo yum -y install containerd #生成默认配置 containerd config default > /etc/containerd/config.toml #替换默认pause镜像 sed -i 's/k8s.gcr.io/pause:3.2/registry.baidubce.com/k8s.gcr.io/pause:3.2/g' /etc/containerd/config.toml #修改默认Cgroup驱动 sed -i 's/SystemdCgroup = false/SystemdCgroup = true/g' /etc/containerd/config.toml #启动containerd systemctl enable containerd.service systemctl restart containerd.service
2、修改kubelet相关启动参数
cp /etc/sysconfig/kubelet /etc/sysconfig/kubelet.backup echo "KUBELET_EXTRA_ARGS=--container-runtime=remote --container-runtime-endpoint=unix:///run/containerd/containerd.sock --cgroup-driver=systemd" >/etc/sysconfig/kubelet systemctl restart kubelet
3、关闭docker服务(按需关闭)
systemctl stop docker.socket systemctl disable docker.socket
4、配置containerd 连接socket
cat >/etc/crictl.yaml<
