【Kubeedge小白安装教程】Centos7.9+K8Sv1.22.17(kubeadm)+Kubeedgev1.13.1部署教程详解(NodePort)----亲测过

其实这两个问题都是因为还没有安装网络插件导致的，kubernetes支持众多的网络插件，详情可参考这里： https://kubernetes.io/docs/concepts/cluster-administration/addons/如果出现sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-ip6tables: No Such fi

安装过程中所有资料获取地址

第一：部署kubernetes1.22版本

这里部署k8s版本为1.22或者1.23版本。这里参考kubeedge支持的程度，选择1.22版本，后续会支持更高的k8s版本。

主机名	ip地址	节点类型	系统版本
k8s-master	192.168.0.61	master、etcd、worker	centos7.9
edge-01	192.168.0.232		centos7.9

环境准备

准备工作需要在所有节点上操作，包含的过程如下：

配置主机名
添加/etc/hosts
清空防火墙
设置yum源
配置时间同步
关闭swap
配置内核参数
加载ip_vs内核模块
安装Containerd
安装kubelet、kubectl、kubeadm

配置主机名

hostnamectl set-hostname k8s-master  &&  bash
hostnamectl set-hostname edge-01  &&  bash

添加/etc/hosts

cat >>  /etc/hosts  << EOF
192.168.0.61 k8s-master
192.168.0.232 edge-01
EOF

清空防火墙

#关闭防火墙：
systemctl stop firewalld
systemctl disable firewalld
#关闭selinux：
sed -i 's/enforcing/disabled/' /etc/selinux/config # 永久
setenforce 0 # 临时
#关闭swap：
swapoff -a # 临时
sed -i 's/.*swap.*/#&/' /etc/fstab # 永久

设置yum源

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
wget -O /etc/yum.repos.d/epel.repo https://mirrors.aliyun.com/repo/epel-7.repo

配置时间同步

yum install -y chrony -y 
cat > /etc/chrony.conf << EOF
server ntp.aliyun.com iburst
stratumweight 0
driftfile /var/lib/chrony/drift
rtcsync
makestep 10 3
bindcmdaddress 127.0.0.1
bindcmdaddress ::1
keyfile /etc/chrony.keys
commandkey 1
generatecommandkey
logchange 0.5
logdir /var/log/chrony
EOF

systemctl enable --now chronyd 
chronyc sources

配置内核参数

cat > /etc/modprobe.d/k8s.conf <<EOF
#!/bin/bash
#modprobe -- br_netfilter
modprobe -- ip_vs
modprobe -- ip_vs_rr
modprobe -- ip_vs_wrr
modprobe -- ip_vs_sh
modprobe -- nf_conntrack_ipv4
EOF

chmod 755 /etc/modprobe.d/k8s.conf && \
bash /etc/modprobe.d/k8s.conf && \
lsmod | grep -E "ip_vs|nf_conntrack_ipv4"

这些内核模块主要用于后续将kube-proxy的代理模式从iptables切换至ipvs

在linux kernel 4.19版本已经将nf_conntrack_ipv4 更新为 nf_conntrack，如果在加载内核时出现如下报错：modprobe: FATAL: Module nf_conntrack_ipv4 not found.，则将nf_conntrack_ipv4 改为nf_conntrack即可

加载ip_vs内核模块

cat > /etc/sysctl.conf << EOF
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-arptables = 1
net.ipv4.ip_forward=1
net.ipv4.ip_forward_use_pmtu = 0
EOF

sysctl --system
sysctl -a|grep "ip_forward"

如果出现sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-ip6tables: No Such file or directory这样的错误，可以忽略

bridge-nf 使 netfilter 可以对 Linux 网桥上的 IPv4/ARP/IPv6 包过滤。比如，设置net.bridge.bridge-nf-call-iptables=1后，二层的网桥在转发包时也会被 iptables的 FORWARD 规则所过滤。常用的选项包括：

net.bridge.bridge-nf-call-arptables：是否在 arptables 的 FORWARD 中过滤网桥的 ARP 包
net.bridge.bridge-nf-call-ip6tables：是否在 ip6tables 链中过滤 IPv6 包
net.bridge.bridge-nf-call-iptables：是否在 iptables 链中过滤 IPv4 包
net.bridge.bridge-nf-filter-vlan-tagged：是否在 iptables/arptables 中过滤打了 vlan 标签的包。
fs.may_detach_mounts：centos7.4引入的新内核参数，用于在容器场景防止挂载点泄露

安装Docker

# 安装docker
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo
yum makecache fast
yum -y install docker-ce-20.10.0-3.el7   #这里指定版本

# 生成docker配置文件
mkdir -p /etc/docker/
touch /etc/docker/daemon.json
cat > /etc/docker/daemon.json << EOF
{
 "registry-mirrors":["https://rsbud4vc.mirror.aliyuncs.com","https://registry.docker-cn.com","https://docker.mirrors.ustc.edu.cn","https://dockerhub.azk8s.cn","http://hub-mirror.c.163.com","http://qtid6917.mirror.aliyuncs.com", "https://rncxm540.mirror.aliyuncs.com"],
  "exec-opts": ["native.cgroupdriver=systemd"]
} 
EOF

# 启动docker
systemctl enable docker --now
systemctl start docker
systemctl status docker
docker --version

安装kubelet、kubectl、kubeadm

cat <<EOF > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
enabled=1
gpgcheck=0
repo_gpgcheck=0
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF

yum list kubeadm --showduplicates

yum install -y kubelet-1.22.17-0 kubeadm-1.22.17-0 kubectl-1.22.17-0
systemctl enable kubelet  # 注意: 在这里kubelet是无法正常启动的，只是确保其可以开机自启

部署master

部署master，只需要在master节点上配置，包含的过程如下：

生成kubeadm.yaml文件
编辑kubeadm.yaml文件
根据配置的kubeadm.yaml文件部署master

安装master节点：

kubeadm init --apiserver-advertise-address=192.168.0.61  --image-repository registry.aliyuncs.com/google_containers --kubernetes-version v1.22.17 --service-cidr=10.96.0.0/12  --pod-network-cidr=10.244.0.0/16

如果k8s集群出现问题，就重置再进行部署：

# 重置集群
kubeadm reset
# 停止kubelet
systemctl stop kubelet
# 删除已经部署的容器
crictl --runtime-endpoint unix:///var/run/containerd/containerd.sock ps -aq |xargs crictl --runtime-endpoint unix:///var/run/containerd/containerd.sock rm 
# 清理所有目录
rm -rf /etc/kubernetes /var/lib/kubelet /var/lib/etcd /var/lib/cni/

此时如下看到类似如下输出即代表master安装完成：

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 192.168.200.129:6443 --token abcdef.0123456789abcdef \
        --discovery-token-ca-cert-hash sha256:d3e83e7c3907dc42039bbf845022d1fa95bba9a4f5af018c17809e269ec6175d

配置访问集群：

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

配置网络

在master完成部署之后，发现两个问题：

master节点一直notready
coredns pod一直pending

其实这两个问题都是因为还没有安装网络插件导致的，kubernetes支持众多的网络插件，详情可参考这里： https://kubernetes.io/docs/concepts/cluster-administration/addons/

caclico网站为：https://docs.tigera.io/calico/latest/getting-started/kubernetes/

我们这里使用calico网络插件，安装如下：

curl https://raw.githubusercontent.com/projectcalico/calico/v3.26.0/manifests/calico.yaml -O
kubectl apply -f calico.yaml

查看节点状态：

[root@k8s-master ~]# kubectl get node
NAME         STATUS   ROLES                  AGE   VERSION
k8s-master   Ready    control-plane,master   15m   v1.22.17

检查master组件是否正常：

[root@k8s-master ~]# kubectl get pods -n kube-system
NAME                                      READY   STATUS    RESTARTS   AGE

kube-controller-manager-k8s-master        1/1     Running   1          16m
kube-proxy-hdwsw                          1/1     Running   0          16m
kube-scheduler-k8s-master                 1/1     Running   1          16m

让master节点成为worker节点

这里因为资源不足的原因，使用master单节点。去除master污点，让master成为工作节点。

#查看污点
[root@k8s-master ~]# kubectl describe node k8s-master |grep Taint
Taints:             node-role.kubernetes.io/master:NoSchedule
#去除污点
[root@k8s-master ~]# kubectl taint node k8s-master node-role.kubernetes.io/master-
#检查
[root@k8s-master ~]# kubectl describe node k8s-master |grep Taint
Taints:             <none>

#在kubernetes群集中创建Nginx
kubectl create deployment nginx --image=nginx 
kubectl expose deployment nginx --port=80 --type=NodePort
kubectl scale deployment  nginx --replicas=2  #pod副本的数量增加到10个
kubectl get pod,svc -o wide

第二：部署kubeedge

部署cloudcore

获取keadm工具

wget https://github.com/kubeedge/kubeedge/releases/download/v1.13.1/keadm-v1.13.1-linux-amd64.tar.gz #下载
tar -zxvf keadm-v1.13.1-linux-amd64.tar.gz #解压
cp keadm-v1.13.1-linux-amd64/keadm/keadm /usr/local/bin/  #移动keadm
keadm version  #测试

cloudcore部署

[root@k8s-master ~]# keadm init --advertise-address=192.168.0.61 --set iptablesManager.mode="external" --profile version=v1.13.1
#192.168.0.61为master的IP

修改cloudcore的svc类型为NodePort


#修改yaml文件
kubectl edit svc cloudcore -n kubeedge
  type: NodePort  #这个需要修改
  
  
  [root@k8s-master ~]# kubectl get svc -n kubeedge  #这里暴露的端口尤其是10000的对外端口有用

[root@k8s-master ~]#

因为边缘计算的硬件条件都不好，这里我们需要打上标签，让一些应用不扩展到edge节点上去

kubectl get daemonset -n kube-system |grep -v NAME |awk '{print $1}' | xargs -n 1 kubectl patch daemonset -n kube-system --type='json' -p='[{"op": "replace","path": "/spec/template/spec/affinity","value":{"nodeAffinity":{"requiredDuringSchedulingIgnoredDuringExecution":{"nodeSelectorTerms":[{"matchExpressions":[{"key":"node-role.kubernetes.io/edge","operator":"DoesNotExist"}]}]}}}}]'

kubectl get daemonset -n metallb-system |grep -v NAME |awk '{print $1}' | xargs -n 1 kubectl patch daemonset -n metallb-system --type='json' -p='[{"op": "replace","path": "/spec/template/spec/affinity","value":{"nodeAffinity":{"requiredDuringSchedulingIgnoredDuringExecution":{"nodeSelectorTerms":[{"matchExpressions":[{"key":"node-role.kubernetes.io/edge","operator":"DoesNotExist"}]}]}}}}]'

但凡是daemonset的都不可以去占用edge节点的硬件资源

部署metrics-server

#[root@k8s-master ~]# 
wget https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml
kubectl apply -f components.yaml
kubectl get pods -n kube-system

因为没有证书的缘故，metrics-server一只呈现这样的状态
修改yaml文件，让metrics-server不需要识别证书

kubectl patch deploy metrics-server -n kube-system --type='json' -p='[{"op":"add","path":"/spec/template/spec/containers/0/args/-","value":"--kubelet-insecure-tls"}]'

metrics-server正常运行

第三：部署edgecore

获取keadm工具

wget https://github.com/kubeedge/kubeedge/releases/download/v1.13.1/keadm-v1.13.1-linux-amd64.tar.gz #下载
tar -zxvf keadm-v1.13.1-linux-amd64.tar.gz #解压
cp keadm-v1.13.1-linux-amd64/keadm/keadm /usr/local/bin/  #复制keadm
keadm version  #测试

安装docker-ce

cat > /etc/docker/daemon.json << EOF
{
  "exec-opts": ["native.cgroupdriver=cgroupfs"],
  "registry-mirrors": ["https://rsbud4vc.mirror.aliyuncs.com","https://registry.docker-cn.com","https://docker.mirrors.ustc.edu.cn","https://dockerhub.azk8s.cn","http://hub-mirror.c.163.com","http://qtid6917.mirror.aliyuncs.com", "https://rncxm540.mirror.aliyuncs.com"]
}
EOF

# 启动docker
systemctl enable docker --now
systemctl start docker
systemctl status docker
docker --version

这里注意：cgroupdriver=cgroupfs。修改为systemd则会出现两者之间不一致的问题

部署edgecore

在master节点上获取token

[root@k8s-master ~]# keadm gettoken

1.13版本默认使用containerd，如果需要使用docker，runtimetype和remote runtime endpoint都要在keadm join时指定

如果都不可以，edgecore加入不进k8s集群，使用这个网站

检查是否安装成功

在edgecore节点上运行容器

第四：启用 kubectl logs 功能

在master节点上运行

启用Kubectl logs/exec/attach等能力 | KubeEdge

[root@k8s-master ~]# iptables -t nat -A OUTPUT -p tcp --dport 10350 -j DNAT --to 192.168.0.61:10003   #这个IP要注意
[root@k8s-master ~]# iptables -t nat -A OUTPUT -p tcp --dport 10351 -j DNAT --to 192.168.0.61:10003   #这个IP要注意

[root@edge-01 ~]# vim /etc/kubeedge/config/edgecore.yaml  #修改edgeStream下的enable: true为这个

  edgeStream:
    enable: true   #只修改这个
