CentOS7使用yum方式安装Containerd 

# 安装需要的软件包， yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖的
yum install -y yum-utils device-mapper-persistent-data lvm2
# 设置 yum 源
# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum install containerd -y

# 安装的版本是1.4.12

$ containerd config default > /etc/containerd/config.toml
$ systemctl restart containerd
$ systemctl status containerd

# 替换 containerd 默认的 sand_box 镜像，编辑 /etc/containerd/config.toml

sandbox_image = "registry.aliyuncs.com/google_containers/pause:3.2"

# 重启containerd
$ systemctl daemon-reload
$ systemctl restart containerd

安装的containerd.io.x86_64 0:1.4.13-3.1.el7版本默认配置文件内容

修改 containerd 配置文件

  • root 容器存储路径，修改成磁盘空间充足的路径
  • sandbox_image pause 镜像名称以及镜像tag（一定要可以拉取到 pause 镜像的，否则会导致集群初始化的时候 kubelet 重启失败）
  • bin_dir cni 插件存放路径，yum 安装的 containerd 默认存放在 /opt/cni/bin 目录下
