二进制文件方式部署k8s(3)

Containerd安装

Containerd被大量用于k8s作为其容器运行时，它是一个行业标准的容器运行时，也是一个轻量级、高性能的守护进程，负责管理容器的完整生命周期

启动服务并设置开机启动

所有节点执行

bash 复制代码

systemctl daemon-reload
systemctl enable --now containerd
systemctl restart containerd

配置crictl客户端连接的运行时位置

所有节点执行

解压crictl

bash 复制代码

tar xf crictl-v*-linux-amd64.tar.gz -C /usr/bin/

生成配置文件

bash 复制代码

cat > /etc/crictl.yaml <<EOF
runtime-endpoint: unix:///run/containerd/containerd.sock
image-endpoint: unix:///run/containerd/containerd.sock
timeout: 10
debug: false
EOF

测试

bash 复制代码

systemctl restart  containerd

bash 复制代码

crictl info
systemctl status containerd

应该会出现crictl配置信息以及containerd服务正常运行的信息
