高可用Kubernetes集群实战(二)

安装containerd 容器运行时

[root@k8sm1 ~]# yum install -y containerd.io-1.6.6

生成containerd 配置文件

创建配置文件存储目录

[root@k8sm1 ~]# mkdir -p /etc/containerd

生成配置文件

[root@k8sm1 ~]# containerd config default > /etc/containerd/config.toml

修改配置文件

修改sandbox_image = "registry.aliyuncs.com/google_containers/pause:3.8"

SystemdCgroup = true

启动containerd 并设置自启

[root@k8sm1 ~]# systemctl enable containerd --now

配置containerd 加速

创建加速器配置文件

[root@k8sm1 ~]# mkdir -p /etc/containerd/certs.d/docker.io
[root@k8sm1 ~]# vim /etc/containerd/certs.d/docker.io/hosts.toml

[host."https://xxx.mirror.aliyuncs.com",host."https://registry.docker-cn.com"]
  capabilities = ["pull","push"]

[plugins."io.containerd.grpc.v1.cri".registry]
   config_path = "/etc/containerd/certs.d"

重启containerd

安装docker

[root@k8sm1 ~]# yum install -y docker-ce
[root@k8sm1 ~]# systemctl enable docker --now

配置docker 加速器

vim /etc/docker/daemon.json

安装k8s 基础软件包

[root@k8sm1~]# yum install -y kubelet-1.25.0 kubeadm-1.25.0 kubectl-1.25.0

配置kubelet 开机自启

[root@k8sm1 ~]# systemctl enable kubelet
Created symlink from /etc/systemd/system/multi-user.target.wants/kubelet.service to /usr/lib/systemd/system/kubelet.service.
[root@k8sm1 ~]#
