Ubuntu server22.04 ，kubernetes（k8s）1.24.0，congtainerd 1.6.4安装笔记

Posted 2022-05-16 寂静的星空

闲来无事写个新版本的安装记录

ip规划

角色	IP
master1	192.168.0.221
node1	192.168.0.222
node2	192.168.0.223
node3	192.168.0.224
k8s-node-01	192.168.0.245

时间同步

apt-get install ntpdate -y

ntpdate time.windows.com

允许 iptables 检查桥接流量

cat <<EOF | sudo tee /etc/modules-load.d/k8s.conf

br_netfilter

EOF

cat <<EOF | sudo tee /etc/sysctl.d/k8s.conf

net.bridge.bridge-nf-call-ip6tables = 1

net.bridge.bridge-nf-call-iptables = 1

EOF

sudo sysctl --system

Ubuntu 18.04 下关闭 swap 的操作

关闭swap

swapoff -a # 临时

sed -ri s/.*swap.*/#&/ /etc/fstab # 永久

安装 Docker

也可以参考其它过程安装

apt-get install docker.io

如果需要配置为开机启动，可执行以下命令

systemcd enable docker

systemcd start docker

配置docker加速器

mkdir -p /etc/docker

tee /etc/docker/daemon.json <<-EOF

"registry-mirrors": ["https://1e60esib.mirror.aliyuncs.com"],

"exec-opts": ["native.cgroupdriver=systemd"],

"log-driver": "json-file",

"log-opts":

"max-size": "100m"

EOF

systemctl daemon-reload

systemctl restart docker

安装docker-ce ,containerd.io

1 安装

削除旧的版本

$ sudo apt-get remove docker docker-engine docker.io containerd runc

$sudo apt-get update

安装相关支持

sudo apt-get install \\

apt-transport-https \\

ca-certificates \\

curl \\

gnupg \\

lsb-release

添加证书

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

$ echo \\

"deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \\

$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

安装

$ sudo apt-get update

$ sudo apt-get install containerd.io docker-ce docker-ce-cli

配置containerd

生成containerd默认配置文件

mkdir -p /etc/containerd

containerd config default | sudo tee /etc/containerd/config.toml

修改配置文件

sed -i s/SystemdCgroup = false/SystemdCgroup = true/ /etc/containerd/config.toml && \\

grep SystemdCgroup -B 11 /etc/containerd/config.toml

老版本要手动追加这个参数SystemdCgroup = true

显示内容

[plugins."io.containerd.grpc.v1.cri".containerd.runtimes.runc.options]

BinaryName = ""

CriuImagePath = ""

CriuPath = ""

CriuWorkPath = ""

IoGid = 0

IoUid = 0

NoNewKeyring = false

NoPivotRoot = false

Root = ""

ShimCgroup = ""

SystemdCgroup = true

配置容器镜像加速器

sed -i s#endpoint = ""#endpoint = "https://xx4bwyg2.mirror.aliyuncs.com"#g /etc/containerd/config.toml && \\

grep endpoint -B 5 /etc/containerd/config.toml

sed -i s#sandbox_image = "k8s.gcr.io/pause:*"#sandbox_image = "registry.aliyuncs.com/google_containers/pause:3.6"#g /etc/containerd/config.toml && \\

grep sandbox_image /etc/containerd/config.toml

重启服务器加载配置

systemctl daemon-reload

systemctl restart containerd.service

安装 K8S

安装 K8S软件包

更新 apt 包索引并安装使用 Kubernetes apt 仓库所需要的包：

sudo apt-get update

sudo apt-get install -y apt-transport-https ca-certificates curl

下载 Google Cloud 公开签名秘钥：

sudo curl -fsSLo /usr/share/keyrings/kubernetes-archive-keyring.gpg https://packages.cloud.google.com/apt/doc/apt-key.gpg

添加 Kubernetes apt 仓库：

echo "deb [signed-by=/usr/share/keyrings/kubernetes-archive-keyring.gpg] https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list

阿里云源安装可以忽略上边的

apt-get update && apt-get install -y apt-transport-https

curl https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | apt-key add -

cat <<EOF >/etc/apt/sources.list.d/kubernetes.list

deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main

EOF

更新 apt 包索引，安装 kubelet、kubeadm 和 kubectl，并锁定其版本：

apt-get update

sudo apt-get install -y kubelet kubeadm kubectl

sudo apt-mark hold kubelet kubeadm kubectl

部署Kubernetes Master

6.1 创建kubeadm配置文件

导出默认初始化配置

kubeadm config print init-defaults > kubeadm-config.yaml

vi kubeadm-config.yaml
