部署环境准备

  1. 关闭swap分区：swapoff -a
  2. 关闭selinux： setenforce 0
  3. 检查内核模块 
    modprobe overlay
modprobe br_netfilter

  4. 设置k8s内核配置选项 

    cat <<EOF | sudo tee /etc/sysctl.d/99-kubernetes-cri.conf
net.bridge.bridge-nf-call-iptables  = 1
net.bridge.bridge-nf-call-ip6tables = 1
net.ipv4.ip_forward                 = 1
EOF
    执行sysctl -p /etc/sysctl.d/99-kubernetes-cri.conf 使其生效

  5. 关闭防火墙 

    systemctl stop firewalld

  6. 修改hosts文件

机器ip lab1
  1. 修改hostname 
    hostname lab1

安装runc

wget https://github.com/Loongson-Cloud-Community/runc/releases/download/v1.1.12/runc-seccomp-1.1.12-abi2.0-bin.tar.gz
tar -xf runc-seccomp-1.1.12-abi2.0-bin.tar.gz
mv runc-seccomp-1.1.12-abi2.0-bin/runc-static /usr/local/bin/runc

安装containerd

  1. 下载安装containerd二进制 

    wget https://github.com/Loongson-Cloud-Community/containerd/releases/download/v1.7.13/containerd-1.7.13-static-abi2.0-bin.tar.gz
tar -xf containerd-1.7.13-static-abi2.0-bin.tar.gz
mv containerd-1.7.13-static-abi2.0-bin/* /usr/local/bin/

  2. 生成containerd默认配置文件 

    mkdir -p /etc/containerd
containerd config default > /etc/containerd/config.toml

  3. 修改 /etc/containerd/config.toml， 将systemd 作为容器的cgroup driver:

 [plugins."io.containerd.grpc.v1.cri".containerd.runtimes.runc]
   ...
   [plugins."io.containerd.grpc.v1.cri".containerd.runtimes.runc.options]
     SystemdCgroup = true
  1. 修改 /etc/containerd/config.toml， 指定的pause容器部分:
[plugins."io.containerd.grpc.v1.cri"]
  sandbox_image = "lcr.loongnix.cn/kubernetes/pause:3.9"
  1. 为了通过 systemd 启动 containerd ，请还需要从 https://raw.githubusercontent.com/containerd/containerd/main/containerd.service 下载 containerd.service 单元文件，并将其放置在 /etc/systemd/system/containerd.service 中
wget https://raw.githubusercontent.com/containerd/containerd/main/containerd.service
mv containerd.service /etc/systemd/system/containerd.service
  1. 启动containerd
systemctl daemon-reload
systemctl start containerd

k8s安装

mkdir -p /tmp/rpms
cd /tmp/rpms

配置crictl

 ## 配置runtime-endpoint
 crictl config runtime-endpoint unix:///run/containerd/containerd.sock
 ## 配置image-endpoint
 crictl config image-endpoint unix:///run/containerd/containerd.sock

创建k8s集群

kubeadm init \
--image-repository lcr.loongnix.cn/kubernetes \
--kubernetes-version v1.29.0 \
--cri-socket=/run/containerd/containerd.sock \
--pod-network-cidr=10.244.0.0/16 -v=5

出现类似如下日志，代表启动成功

Your Kubernetes control-plane has initialized successfully!

To start using your cluster, you need to run the following as a regular user:

  mkdir -p $HOME/.kube
  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
  sudo chown $(id -u):$(id -g) $HOME/.kube/config

Alternatively, if you are the root user, you can run:

  export KUBECONFIG=/etc/kubernetes/admin.conf

You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
  https://kubernetes.io/docs/concepts/cluster-administration/addons/

Then you can join any number of worker nodes by running the following on each as root:

kubeadm join 10.130.0.193:6443 --token dpl4ij.njlpwjg3bzg8up0k \
    --discovery-token-ca-cert-hash sha256:7990c6a4850f6c4e1f1a45855e76fb0852e8113f63ff0b8ddfa252f3da2d5d10
