Kubernetes 使用 containerd 做为 CRI

基础

disable docker

$ systemctl disable docker
1

enable containerd

$ systemctl enable containerd
1

初始化 containerd 配置

$ containerd config default > /etc/containerd/config.toml
1

修改 sandbox 镜像,最终设置成这样 sandbox_image = “registry.aliyuncs.com/google_containers/pause:3.6”

$ vi /etc/containerd/config.toml
1

启动 containerd

$ systemctl restart containerd
1

kubeadm 配置

生成 kubeadm 配置文件

$ kubeadm config print init-defaults > kubeadm.conf
1

修改 kubeadm 配置文件

criSocket: /run/containerd/containerd.sock

imageRepository: registry.aliyuncs.com/google_containers
kind: ClusterConfiguration
kubernetesVersion: 1.23.6
podSubnet: 10.244.0.0/16

kubeadm 安装

$ kubeadm init --config kubeadm.conf

crictl warning

WARN[0000] runtime connect using default endpoints: [unix:///var/run/dockershim.sock unix:///run/containerd/containerd.sock unix:///run/crio/crio.sock]. As the default settings are now deprecated, you should set the endpoint instead.

修改 /etc/crictl.yaml

runtime-endpoint: unix:///run/containerd/containerd.sock
image-endpoint: unix:///run/containerd/containerd.sock
timeout: 10
debug: false

join

join 时 可以加 参数

kubeadm join 1.2.3.215:6443 --token yzgtl1.7e1jmn5iqduytvym --discovery-token-ca-cert-hash sha256:45f2e5e339ea45125dd17ac15b16ef32a9c96e0c1f573cdb7c51e092fb265fe5 --cri-socket="unix:///var/run/containerd/containerd.sock"
