安装常用工具

安装vim、net-tools、bash-completion、wget常用的工具软件。

# yum install vim net-tools bash-completion  wget -y 
# source  /etc/profile.d/bash_completion.sh
# echo 'set paste'  >> ~/.vimrc

二、安装配置containerd

该章节的所有操作所有节点上均要执行。

安装containerd

# yum install containerd.io-1.6.14 cri-tools -y
# crictl config runtime-endpoint unix:///var/run/containerd/containerd.sock
# systemctl restart containerd ; systemctl enable containerd

设置containerd镜像加速

containerd 运行时配置加速：在[plugins.”io.containerd.grpc.v1.cri”.registry.mirrors]行下添加内容：[plugins.”io.containerd.grpc.v1.cri”.registry.mirrors.”docker.io”] 换行再添加 endpoint = [“https://frz7i079.mirror.aliyuncs.com”]。蓝色字体及为需要添加的内容。

# containerd config default > /etc/containerd/config.toml
# vim /etc/containerd/config.toml
      [plugins."io.containerd.grpc.v1.cri".registry.mirrors]
      [plugins."io.containerd.grpc.v1.cri".registry.mirrors."docker.io"]
        endpoint = ["https://sdmy9bft.mirror.aliyuncs.com"]

设置cgroup驱动及sandbox_image地址

在/etc/containerd/config.toml文件修改runc.options选项SystemdCgroup = true。设置sandbox_image镜像下载地址为阿里云的地址。

# sed   -i    's/SystemdCgroup.*/SystemdCgroup\ =\ true/g' /etc/containerd/config.toml 
# sed   -i    's#sandbox_image.*#sandbox_image\ =\ \"registry.aliyuncs.com/google_containers/pause:3.7\"#g'   /etc/containerd/config.toml
# systemctl restart containerd

三、安装容器工具

该章节的所有操作所有节点上均要执行。

安装cni插件

在网址：https://github.com/containernetworking/plugins/releases/ 中下载软件包。

# wget https://github.com/containernetworking/plugins/releases/download/v1.1.1/cni-plugins-linux-amd64-v1.1.1.tgz
# mkdir -p /opt/cni/bin/  
# tar -zxf   cni-plugins-linux-amd64-v1.1.1.tgz  -C  /opt/cni/bin/

安装nerdctl工具

nerdctl工具是操作containerd的客户端，可以实现操作containerd和docker一样命令集操作。

在网址：https://github.com/containerd/nerdctl/releases 中下载软件包只需下载精简包即可（不带full字样的）。

# wget https://github.com/containerd/nerdctl/releases/download/v1.1.0/nerdctl-1.1.0-linux-amd64.tar.gz
