安装 crictl 工具和 cni 插件

一、手动安装 crictl 工具

https://github.com/kubernetes-sigs/cri-tools

建议手动下载 https://github.com/kubernetes-sigs/cri-tools/tags 。

VERSION="v1.29.0"

wget https://github.com/kubernetes-sigs/cri-tools/releases/download/$VERSION/crictl-$VERSION-linux-amd64.tar.gz
sudo tar zxvf crictl-$VERSION-linux-amd64.tar.gz -C /usr/local/bin
rm -f crictl-$VERSION-linux-amd64.tar.gz

wget https://github.com/kubernetes-sigs/cri-tools/releases/download/$VERSION/critest-$VERSION-linux-amd64.tar.gz
sudo tar zxvf critest-$VERSION-linux-amd64.tar.gz -C /usr/local/bin
rm -f critest-$VERSION-linux-amd64.tar.gz

增加软链接到 /usr/bin ，有些时候 /usr/local/bin 不在 $PATH 中，会报错。

ln -s /usr/local/bin/crictl /usr/bin/crictl
ln -s /usr/local/bin/critest /usr/bin/critest

创建配置文件 /etc/crictl.yaml

runtime-endpoint: unix:///run/containerd/containerd.sock

二、手动安装 cni 插件

https://github.com/containernetworking/plugins
https://minikube.sigs.k8s.io/docs/faq/#how-do-i-install-containernetworking-plugins-for-none-driver

建议手动下载。

CNI_PLUGIN_VERSION="v1.4.0"
CNI_PLUGIN_TAR="cni-plugins-linux-amd64-$CNI_PLUGIN_VERSION.tgz"
CNI_PLUGIN_INSTALL_DIR="/opt/cni/bin"

curl -LO "https://github.com/containernetworking/plugins/releases/download/$CNI_PLUGIN_VERSION/$CNI_PLUGIN_TAR"
sudo mkdir -p "$CNI_PLUGIN_INSTALL_DIR"
sudo tar -xf "$CNI_PLUGIN_TAR" -C "$CNI_PLUGIN_INSTALL_DIR"
rm "$CNI_PLUGIN_TAR"

三、yum 安装

https://developer.aliyun.com/mirror/kubernetes

cat <<EOF | tee /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes-new/core/stable/v1.28/rpm/
enabled=1
gpgcheck=1
gpgkey=https://mirrors.aliyun.com/kubernetes-new/core/stable/v1.28/rpm/repodata/repomd.xml.key
EOF
setenforce 0
yum install -y kubelet kubeadm kubectl
systemctl enable kubelet && systemctl start kubelet

这个步骤会安装 kubeadm、kubectl、kubelet、conntrack-tools、cri-tools、kubernetes-cni、libnetfilter_cthelper、libnetfilter_cttimeout、libnetfilter_queue、socat 包。
