本文轉載自查看原文 2021-02-10 15:07 480 K8S

1. 硬件要求

Master機器至少滿足2C4G，負載節點不做要求，最少是1C1G。

2. Centos安裝

1. 腳本安裝

PS:在安裝前請確保已經安裝了Docker,具體的DockerDokcer安裝

具體部署方法如下（在所有master和node節點部署）:

export REGISTRY_MIRROR=https://registry.cn-hangzhou.aliyuncs.com
curl -sSL https://kuboard.cn/install-script/v1.17.x/install_kubelet.sh | sh -s 1.17.2 #最后的版本改成自己需要的版本

該腳本內容如下，其Docker版本指定安裝19.03.8：

#!/bin/bash

# 在 master 節點和 worker 節點都要執行

# 安裝 docker
# 參考文檔如下

# 卸載舊版本

# 安裝kubelet、kubeadm、kubectl
# 將 ${1} 替換為 kubernetes 版本號，例如 1.17.2
yum install -y kubelet-${1} kubeadm-${1} kubectl-${1}

# 修改docker Cgroup Driver為systemd

# # 修改為 ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock --exec-opt native.cgroupdriver=systemd
# 如果不修改，在添加 worker 節點時可能會碰到如下錯誤

# 設置 docker 鏡像，提高 docker 鏡像下載速度和穩定性
# 如果您訪問 https://hub.docker.io 速度非常穩定，亦可以跳過這個步驟
curl -sSL https://kuboard.cn/install-script/set_mirror.sh | sh -s ${REGISTRY_MIRROR}

# 重啟 docker，並啟動 kubelet
systemctl daemon-reload
systemctl restart docker
systemctl enable kubelet && systemctl start kubelet

docker version

如果進行過前面的全部步驟，可以參考該腳本安裝剩余內容。

2. 初始化Master節點

# 只在 master 節點執行
# 替換 x.x.x.x 為 master 節點實際 IP（請使用內網 IP）
# export 命令只在當前 shell 會話中有效，開啟新的 shell 窗口后，如果要繼續安裝過程，請重新執行此處的 export 命令
export MASTER_IP=x.x.x.x
# 替換 apiserver.demo 為 您想要的 dnsName
export APISERVER_NAME=apiserver
# Kubernetes 容器組所在的網段，該網段安裝完成后，由 kubernetes 創建，事先並不存在於您的物理網絡中
export POD_SUBNET=10.100.0.1/16
echo "${MASTER_IP}    ${APISERVER_NAME}" >> /etc/hosts
curl -sSL https://kuboard.cn/install-script/v1.17.x/init_master.sh | sh -s 1.17.2 #最后的版本號修改成自己安裝的

具體腳本如下:

#!/bin/bash

# 只在 master 節點執行

# 腳本出錯時終止執行
set -e

if [ ${#POD_SUBNET} -eq 0 ] || [ ${#APISERVER_NAME} -eq 0 ]; then
  echo -e "\033[31;1m請確保您已經設置了環境變量 POD_SUBNET 和 APISERVER_NAME \033[0m"
  echo 當前POD_SUBNET=$POD_SUBNET
  echo 當前APISERVER_NAME=$APISERVER_NAME
  exit 1
fi


# 查看完整配置選項 https://godoc.org/k8s.io/kubernetes/cmd/kubeadm/app/apis/kubeadm/v1beta2
rm -f ./kubeadm-config.yaml
cat <<EOF > ./kubeadm-config.yaml
apiVersion: kubeadm.k8s.io/v1beta2
kind: ClusterConfiguration
kubernetesVersion: v${1}
imageRepository: registry.cn-hangzhou.aliyuncs.com/google_containers
controlPlaneEndpoint: "${APISERVER_NAME}:6443"
networking:
  serviceSubnet: "10.96.0.0/16"
  podSubnet: "${POD_SUBNET}"
  dnsDomain: "cluster.local"
EOF

# kubeadm init
# 根據您服務器網速的情況，您需要等候 3 - 10 分鍾
kubeadm init --config=kubeadm-config.yaml --upload-certs

# 配置 kubectl
rm -rf /root/.kube/
mkdir /root/.kube/
cp -i /etc/kubernetes/admin.conf /root/.kube/config

# 安裝 calico 網絡插件
# 參考文檔 https://docs.projectcalico.org/v3.13/getting-started/kubernetes/self-managed-onprem/onpremises
echo "安裝calico-3.13.1"
rm -f calico-3.13.1.yaml
wget https://kuboard.cn/install-script/calico/calico-3.13.1.yaml
kubectl apply -f calico-3.13.1.yaml

校驗:

# 只在 master 節點執行

# 執行如下命令，等待 3-10 分鍾，直到所有的容器組處於 Running 狀態
watch kubectl get pod -n kube-system -o wide

# 查看 master 節點初始化結果
kubectl get nodes -o wide

3. 初始化node節點

# 只在 master 節點執行
kubeadm token create --print-join-command

上述命令所得2小時內有效。然后在所有node節點執行：

# 只在 worker 節點執行
# 替換 x.x.x.x 為 master 節點的內網 IP
export MASTER_IP=x.x.x.x
# 替換 apiserver.demo 為初始化 master 節點時所使用的 APISERVER_NAME
export APISERVER_NAME=apiserver
echo "${MASTER_IP}    ${APISERVER_NAME}" >> /etc/hosts

# 替換為 master 節點上 kubeadm token create 命令的輸出
kubeadm join apiserver:6443 --token uzggb6.xwsjwd7ij4ditssm     --discovery-token-ca-cert-hash sha256:bafcb44be3f2d1078e69db6ba05424eea35a12356164366deb8e230a9e834cfd

4. 問題

1. Kubelet沒有開放10255端口

修改配置並重啟kubelet：

cat /var/lib/kubelet/kubeadm-flags.env
KUBELET_KUBEADM_ARGS="--cgroup-driver=systemd --network-plugin=cni --pod-infra-container-image=registry.cn-hangzhou.aliyuncs.com/google_containers/pause:3.1 --read-only-port=10255"
systemctl restart kubelet

2. Master無法創建join命令

# kubeadm token create --print-join-command
failed to get join command: no CA certificates found in kubeconfig

去/etc/kubernetes/admin.conf拷一個

3. Ubuntu

1. 確保禁止掉swap分區

K8s的要求，在每個宿主機上執行

sudo swapoff -a

#修改/etc/fstab，注釋掉swap那行，持久化生效
sudo vi /etc/fstab

2. 確保時區和時間正確

每個宿主機上都要確保時區和時間是正確的。

如果時區不正確，請使用下面的命令來修改：

sudo timedatectl set-timezone Asia/Shanghai

#修改后，如果想使得系統日志的時間戳也立即生效，則：
sudo systemctl restart rsyslog

3. 確保每個機器不會自動suspend（待機/休眠）

因為是做服務器用途的嘛，之前在Ubuntu 18.04上是沒遇到過這個問題的，但是不知怎么回事，在Ubuntu 20.04上遇到了這個自動suspend的問題：

May  7 11:44:32 ai05 NetworkManager[838]: <info>  [1588823072.3956] manager: sleep: sleep requested (sleeping: no  enabled: yes)
May  7 11:44:32 ai05 gnome-shell[1603]: Screen lock is locked down, not locking
May  7 11:44:32 ai05 NetworkManager[838]: <info>  [1588823072.3974] manager: NetworkManager state is now ASLEEP
May  7 11:44:32 ai05 systemd[1]: Reached target Sleep.
May  7 11:44:32 ai05 systemd[1]: Starting Suspend...
May  7 11:44:32 ai05 systemd-sleep[27086]: Suspending system...
May  7 11:44:32 ai05 kernel: [ 2426.233326] PM: suspend entry (deep)
May  7 11:44:32 ai05 kernel: [ 2426.252253] Filesystems sync: 0.018 seconds

解決這個問題沒有標准答案，可以在BIOS里設置？在kernel啟動參數設置？在Gnome圖形界面上設置？在網卡相關的命令上設置？Gemfield使用的下面的命令，姑且是起作用了：

sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target

4. 設置iptables可以看到bridged traffic

先確認Linux內核加載了br_netfilter模塊：

lsmod | grep br_netfilter

確保sysctl配置中net.bridge.bridge-nf-call-iptables的值設置為了1。

在Ubuntu 20.04 Server上，這個值就是1。如果你的系統上不一致，使用下面的命令來修改：

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

5. 設置rp_filter的值

每個宿主機上執行。

因為Gemfield的K8s集群即將部署的是calico網絡插件，而calico需要這個內核參數是0或者1，但是Ubuntu20.04上默認是2，這樣就會導致calico插件報下面的錯誤（這是個fatal級別的error）：

int_dataplane.go 1035: Kernel's RPF check is set to 'loose'.  \
This would allow endpoints to spoof their IP address.  \
Calico requires net.ipv4.conf.all.rp_filter to be set to 0 or 1. \
If you require loose RPF and you are not concerned about spoofing, \
this check can be disabled by setting the IgnoreLooseRPF configuration parameter to 'true'.

使用下面的命令來修改這個參數的值：

#修改/etc/sysctl.d/10-network-security.conf
sudo vi /etc/sysctl.d/10-network-security.conf

#將下面兩個參數的值從2修改為1
#net.ipv4.conf.default.rp_filter=1
#net.ipv4.conf.all.rp_filter=1

#然后使之生效
sudo sysctl --system

6. 安裝Docker

Dokcer安裝

7. 開始安裝K8s master

以下的操作只在master宿主機上執行，適合中國大陸地區使用（因為棄用谷歌的源和repo，轉而使用阿里雲的鏡像）：

1. 安裝kubeadm kubeadm kubectl

sudo apt-get update && sudo apt-get install -y ca-certificates curl software-properties-common apt-transport-https curl
curl -s https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | sudo apt-key add -

sudo tee /etc/apt/sources.list.d/kubernetes.list <<EOF 
deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main
EOF

sudo apt-get update
sudo apt-get install -y kubelet kubeadm kubectl
sudo apt-mark hold kubelet kubeadm kubectl

2. 初始化master

注意，這里使用了阿里雲的鏡像，然后使用了非默認的CIDR（一定要和宿主機的局域網的CIDR不一樣！勿謂言之不預也！）

sudo kubeadm init --pod-network-cidr 172.16.0.0/16 \
    --image-repository registry.cn-hangzhou.aliyuncs.com/google_containers

上面的命令執行成功后，會輸出一條和kubeadm join相關的命令，后面加入worker node的時候要使用。另外，給自己的非sudo的常規身份拷貝一個token，這樣就可以執行kubectl命令了：

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

3. 安裝calico插件

k apply -f https://kuboard.cn/install-script/calico/calico-3.13.1.yaml

4. 安裝K8s worker節點

kubeadm token create --print-join-command # 在master節點上執行該命令
kubeadm join xxx.xxx.x.xx:6443 --token jejfa8.ucmaee76674pz6iv \
        --discovery-token-ca-cert-hash sha256:05a3870ed36fece1df131f7597b2c04f331c2f97034fe15f7ca2a2999253a776

執行的前提是在負載節點上要先安裝 kebeadm和kubelet,安裝前還請確認下版本，比如說kubelet的版本和k8s的版本要契合,比如在master上安裝的k8s的版本是1.19那么最好你在負載節點安裝的kubelet也是1.19

選擇對應的版本安裝，如我的master的k8s是1.19.0版本的，那么我在負載節點安裝執行

apt install kubeadm=1.19.0-00
apt install kubelet=1.19.0-00

安裝完成之后在負載節點上執行上面kubeadm token create --print-join-command的結果

kubeadm join xxx.xxx.x.xx:6443 --token jejfa8.ucmaee76674pz6iv \
        --discovery-token-ca-cert-hash sha256:05a3870ed36fece1df131f7597b2c04f331c2f97034fe15f7ca2a2999253a776

4. 驗證

在k8s master節點上執行kubectl get no查看結果

$ k get no
NAME         STATUS   ROLES    AGE     VERSION
didi-cloud   Ready    <none>   2d15h   v1.19.7
k8s-master   Ready    master   3d1h    v1.19.7

如若看到負載節點的狀態已是Ready，說明節點加入成功。
